Description of Equipment
Bulletin 1352 Drive Systems can be designed in several configurations,
depending on the application requirements. Three common system
arrangements are shown in Figure 1-1. The reference section is shown below
each unit. In the basic configuration (1A) which is most common, a diode
bridge in a Line Converter Unit (LCU) provides a constant DC bus voltage for
the Drive Inverters (INU). In addition to the LCU, a Contactor Unit (CTU) 1s
required to isolate the bridge from the input line. A Capacitor Bank Unit
(CBU) is also required to filter the pulsating DC bus voltage from the LCU. A
disconnect device and fuses are provided for isolation of the INU units from
the DC bus voltage. The disconnect also allows maintenance to be performed
on the inverter without shutting down the complete line.
Occasionally, power is fed back to the DC bus from the load through the INU.
This power is capable of being used by other inverter units connected to the
same bus. Unfortunately, some systems cannot always use all of the
regenerated power that is available, such as when a complete line is being
stopped by means of regenerative braking. When this occurs, a method of
dealing with the unused regenerated energy must be provided.
The Bulletin 1352 AC Drive, employs two alternative methods of handling
this excess regenerated power. The first method (Figure 1B) utilizes a
braking chopper and controlled resistors to dissipate the excess energy. This
is generally employed when the regenerated energy exists infrequently in
comparison to the running time of the system. If excess regenerated energy is
available more often or even on a continuous basis, a Line Generating Unit
(LGU) shown in Figure 1C would be used. This unit provides the capability of
regenerating the power back to the AC supply line. The LGU is capable of
controlling the power factor of the regenerated power such that the power
factor is lagging, unity or even leading, similar to the operation of a
synchronous generator. The LGU is also capable of automatic restart after
either a brief power loss or a dip in the supply line voltage. Each of these types
of common DC bus systems is further explained in this manual.
Section 2 details the installation and startup of the Drive System. Section 3
explains the function of the various modules used in a common DC bus system
except for the LGU which is discussed in Section 4. Section 5 provides
assistance in troubleshooting the Drive System with particular emphasis on
the Line Generating Unit and preventive maintenance requirements. Section
6 consists of the reference documents for all units discussed in this manual.
IMPORTANT: In order to minimize the size of this manual it is assumed
that the reader has previous knowledge of the Bulletin 1352 Inverter as a
stand-alone drive and the manner in which parameters are used. The
Bulletin 1352 - 5.0 Installation and Maintenance Manual should be
reviewed prior to working with this System Manual.

Introduction
1352- AC Drive and its associated machinery should plan or
implement the installation, start up and subsequent maintenance
of the Drive. Failure to comply may result in personal injury
and/or equipment damage.
A WARNING: Only qualified personnel familiar with the Bulletin
The Drive is designed to provide circuit protection not only to circuits
connected to it but also to the integral circuits. Therefore, circuit protection
parameters must not be altered. Failure to observe this instruction may
compromise the effectiveness and invalidate any warantees.
Recognized safety regulations must be observed in the installation, start-up
and maintenance procedures. Refer to NFPA 70E, Electrical Safety
Requirement for Employee Workplaces, for installation safety requirements
and general requirements for electrical installation.
Operation - The operation of the Drive should be the responsibility of
personnel familiar with its basic functions. The operator should be informed
of the significance of the Numeric Displays on the Control Panel. In case of a
panel alarm indication, possibly followed by tripping, the operator must be
able to decide whether the Drive should be removed from operation or whether
it should be restarted after resetting the alarm.
Maintenance Work - All maintenance of the Drive must be performed by a-
experienced electrician, familiar with both the drive and solid state
electronics.

bypass mode. The following must be followed:
1) With all power off, disconnect the power cables between the
drive and its output contactor. This provides against voltage
feedback by potentially welded contacts.
2) Take careful note of all power cables and control wiring which
may be live when the Bypass Mode is in operation.

the input cables should be reconnected in the appropriate pattern.
DO NOT make correction by adjusting leads at the motor or output
of the inverter.
A CAUTION: To avoid damage to equipment, motor rotation should
Since all semiconductors exhibit leakage current, the circuits of the Drive
should be regarded as live. Do Not touch any components until the Drive
has been isolated from the supply voltage(s) by disconnects or isolating
switches and it has been verified that there are no voltages present.
. The large capacitors in the Intermediate DC Circuit together with their
resistor discharge circuits are designed to discharge to less than 50V DC

be assumed to be functioning properly. Always measure this voltage prior
to performing any work on the equipment to ensure proper results.

and engineered discharge circuit incorporated in the Drive should
never be modified.
A CAUTION: A power capacitor with even a small remaining

potentially lethal.
. To verify that no voltage is present, a measurement must be taken at the
Intermediate DC bus . The measurement should be made starting with
the 1000V DC range of a multimeter, then switching to lower voltage
ranges as voltage levels permit to prevent over-range indications.
Many voltage testers are unsuitable for checking the Intermediate DC
Circuit voltage, since they do not respond to voltages below approximately
100V DC.
Fatal Voltage is present between the circuit cards and the chassis!
Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from electrical shock,
burn or unintended actuation of controlled equipment.
Recommended practice is to disconnect and lock-out control
equipment from power sources and confirm discharge of stored
energy in capacitors, if present. If it is necessary to work in the
vicinity of energized equipment, only qualified personnel should be
permitted to perform such work, using all applicable safety
practices and protective equipment.
Do not needlessly remove the aluminum and plastic protection
panels during fault tracing. This is usually unnecessary and can
expose personnel to potential hazards from voltage sources present
in the unit. If any protective panel was removed, always replace
the panel before operating the unit.

Line Regenerative System
IMPORTANT: The following section is for Non - Regenerating Systems
only (Line Converter Units). For Regenerative Systems, go to section 2-11
(Line Generating Units).
The following procedure should be followed when starting up the Line
Converter Unit for the first time. A Line Converter Unit can be identified by
the semiconductors which are diodes rather than GTO's, and the LCU does not
have an AC Line Filter Unit. Refer to Figure 1-1 for a graphic comparison of
the two systems.
1. Check that the input power is still off (main disconnect open), inverter
DC disconnects are open and the motors are disconnected.
2. Measure the resistance of the DC bus at the diode bridge of the LCU and
the resistance of each inverter DC bus. A good measuring pointis at the
disconnect terminals. Refer to the connection diagram for the equipment
supplied for specific wire numbers. The resistance should be
approximately 3000 ohms.
3. Close the main CTU disconnect, which will apply power to the DC bus.
No further startup procedure is required for the basic LCU. Continue
with section 2-10 if optional Controlled Braking is included.
4. Refer to the Installation and Maintenance Manual 1352 - 5.0 prior to
closing the inverter DC disconnect.
The braking resistors are normally sized for 10% current for 20 seconds with a
20% duty cycle. Care must be taken to insure that this intermittent duty
rating is not exceeded during startup and testing.
Jumper S1 on the Braking Chopper Control Card 3500-BCC should be
checked to insure that it is connected for the proper AC voltage rating. The
Bulletin 810 Current Relay is adjusted for correct current and time prior to
shipping from the factory. If adjustment of the current or time is required,
refer to Allen-Bradley Publication 810-5.0.
WARNING: The Red LED located on the Chopper Control Card
(3500 - BCC) indicates when the Bus is charged and the Chopper
Control Card has its operating voltages. This LED must not be
considered a safety indicator for servicing the braking system. The
LED does not accurately indicate when all voltages have been
removed from the circuit. Only a DC voltmeter should be used to
test for absence of voltages before servicing any part of the system.
IMPORTANT: The following procedure is only used for systems that
provide for regeneration to the AC line using a Line Generating Unit.

BULLETIN 1352 INSTALLATION & STARTUP
Safety & Codes -
outline provisions for safely installing electrical equipment.
Installation MUST comply with specifications regarding wire
type, conductor sizes, branch circuit protection and disconnect
devices. Failure to do so may result in personal injury and/or
equipment damage.
A WARNING: The National Electrical Code (NEC) or local codes
Unpacking & Inspection - After unpacking the equipment, check the
item(s) received against the bill of lading to assure that the nameplate
description of each item agrees with the material ordered. Inspect the
Bulletin 1352 AC Drive and the other equipment for physical damage, as
stated in the Allen-Bradley / Stromberg Terms and Conditions of Sale.
Important: All claims for breakage and damage whether concealed or
obvious must be made to the carrier by the Customer as soon as possible after
receipt of the shipment. The Allen-Bradley Co. will be glad to render
reasonable assistance in the securing of adjustment for such damage claims.
Remove all packing material, wedges, or braces from within the drive
controller. Operate the contactors and relays manually to assure that they
operate freely.
Storage - If any part of the equipment will not be installed when it is
unpacked, it should be stored in a clean, dry place. The storage temperature
must be between OC (32F) and 60C (140F) with a maximum humidity of 90%,
non-condensing to guard against damage to temperature sensitive
components of the controller. The storage environment must be free of
chemical and other corrosive contaminants (ie. conductive dust, sulfides,
animal matter, etc.). Space heaters may be installed in the enclosure to
prevent condensation.

When choosing the installation site, the following conditions should be
considered:
A.The operating ambient temperature must be between 0C (32F) and 40C
(104F) for NEMA Type 1 enclosures. For NEMA Type 12 enclosures
(which includes a closed loop air conditioning system), the operating
ambient temperature must be between 0C (32F) and 50C (122F).
B. The relative humidity must not exceed 95% non-condensing. Excessive
humidity can cause corrosion or excessive dirt build-up leading to
possible electrical problems.
C. The equipment should be kept clean. Dust build-up inside the enclosure
inhibits proper cooling and decreases the system reliability. If the
environment is excessively dusty, it may require an optional fan & filter
kit modification. Contact the local Allen - Bradley Sales Office for more
details.
D. Only persons familiar with the function of the Drive must have access to
the equipment.
E. The losses in the Drive produce a definite heat dissipation depending on
unit size that tends to warm the air in the room. Attention must be given
to the room ventilation and cooling requirements to ensure the proper
environmental conditions are met. See section 2-6 for more details.
F. Operational altitude is 3300 ft. (1km) maximum without derating.
component damage or a reduction in product life. Wiring or
application errors, such as, undersizing the motor, incorrect or
inadequate AC supply, or ambient temperatures above or below
specified temperature range may result in malfunction of the
Drive.
A CAUTION: Anincorrectly applied or installed drive can result in
Standard Drive Cabinet drawings and equipment installation instructions
are provided in Publication 1352 - 5.01. Refer to this document for sizing and
layout of equipment cabinets and correct mounting procedures. On custom
jobs certified dimension drawings are available, contact the local
Allen - Bradley Sales office.
Grounding Practices - The purpose of grounding is to limit dangerous
voltages on exposed parts to ground, to facilitate proper overcurrent device
operation under ground fault conditions and to help provide electrical
interference suppression.
To ensure a zero voltage reference is available for each element in the system,
two ground networks are provided (Figure 2-1.). Each of these is a copper bus
running the length of the cabinet.
Ground Bus - PE - This is the safety ground required by code. The Ground
Bus can be connected to qualified adjacent building steel ( ie.girder, joist)
or a floor ground loop. Multiple connections are permitted. The ground
bus requires a maximum of 1 ohm to ground.
Signal Bus - TE - Isa separate signal ground. It should be Cadwelded to
the Ground Grid on a dedicated Ground Rod. Do Not ground the TE at the
same place as the PE. The minimum distance from the PE to the TE
ground connection is 10 feet.
Page 2-3
Bulletin 1352 - 5.3 System
IMPORTANT! Generally, grounding should be in accordance with the
National Electrical Code (NEC) and local codes. See NEC article 250 for
ground wire sizing information. Ground wires must be insulated.
Each power feeder from the substation transformer to the drive must be
provided with properly sized ground cables. Simply utilizing the conduit or
cable armor as a ground is not adequate. The conduit or cable armor and
ground wires should be bonded to ground at both ends. Each transformer
enclosure and/or frame must be bonded to ground at a minimum of two
locations.
Each AC motor frame must be bonded to grounded building steel within 20
ft. of its location and tied to the drives PE via ground wires within the power
cables and/or conduit. The conduit or cable armor should be bonded to ground
at both ends.
The Remote Operator’s Control panel must be bonded to grounded
building steel within 30 ft. of its location and tied to the Drives PE via ground
wires within the cable conduit and/or cable tray. Bond conduit or cable armor
at both ends. Cable shield, if required, should be connected to TE at the drive
end only.
Optional Tachometer connections IF required must be routed in grounded
steel conduit. The conduit must be grounded at both ends. Connect the cable
shield to the drive TE Signal bus at the drive end only.
Refer to the instruction manual for each auxiliary device connected to the
drive for any special grounding recommendations.

2-52 Power Connections - The 1352 Drive requires a three-phase supply and an
equipment grounding conductor to earth ground. A neutral conductor of the
three-phase supply is not necessary and is usually not routed to the Drive.
Three-phase wiring and a grounding conductor connects the Drive to the
motor.

The wire sizes must be selected individually, observing all applicable safety
and N.E.C. regulations. The minimum permissible wire size does not
necessarily result in the best operating economy. The minimum
recommended size for the wires between the Drive and the motor is the same
as that used if a main voltage source connection to the motor was used. The
distance between the drive and motor may affect the size of the conductors
used. Consult the wiring diagrams and appropriate NEC regulations to
determine correct power wiring. If assistance is needed, contact your local
Allen-Bradley sales office.
IMPORTANT: The National Electrical Code (NEC) requires that branch
circuit protection of the AC line input power to the drive be provided by
circuit breaker or fusible disconnect switch. The standard Bulletin 1352
Drive does provide this requirement.
The National Electrical Code requires that motor overload protection be
provided in the motor branch circuit. The standard Bulletin 1352 Drive does
not provide this requirement. See Section 6-3 in 1352-5.0 Manual.
motor rotation should be checked while in the bypass mode. If
adjustment is necessary, the input cables should be reconnected as
appropriate. Do Not make correction by adjusting leads at the
motor or output of the drive.
A CAUTION: Ifbypass contactors are supplied with the drive,
Control & Signal Connections - There are several basic configurations of the
1352 control depending on the type of application and what specific VO cards
are used. This section will describe the basic interconnections to external
wiring for the two most common configurations. The general descriptions and
diagrams are based on commonly used wiring schemes. Refer to the
schematics and interconnection drawings supplied with your equipment to
verify the information for your application.
Control & Signal Wires - A shielded type wire is recommended in the control
circuits for protection against interference . A shielded wire is required for
all signal wires and 24VDC wiring. The shield should be grounded at the
drive TE bus only. Both ends should not be grounded. The recommended
conductor cross-sections should be a minimum of 18 AWG (.05082 in). The
best interference suppression is obtained with a cable having an individual
shield for every pair of wires.
IMPORTANT: The Control & Signal wires should be oriented a distance of
at least six (6) inches (150mm) from power cables. Additional noise
suppression practices (including separate steel conduits for signal leads, etc.)
are recommended. See cable/conduit spacing recommendations provided as
part of both the job schematics and in Publication 1352 - 5.01,
Pre -Installation Instructions. We also recommend that 24 VDC Logic
wiring not exceed 50 feet from the drive.
Control & Signal Interconnections Information - For Control & Signal
Interconnection information see Section 2 in Publication 1352 -5.0
Installation & Maintenance Manual.
Interference Suppression - Harmonic and noise voltage disturbances are
present in the supply and output cables of the Bulletin 1352. The interference
caused by the resulting currents can be reduced utilizing the following
methods:
A. Use of cables with a concentric shielded ground conductor.
B. Use of twisted pair shielded wires for control signals.
Page 2-5
Bulletin 1352 - 5.3 System
C. Route the control cables as far away from the power cables as possible,
and avoid long parallel runs of control and power cables.
For detailed information on recommended wiring types, sizes and practices.
refer to the External Wiring Classification Sheets supplied with your
equipment.
2-5.5 Optional Controlled Braking - The Chopper Control Braking Unit is
supplied with the drive, mounted and wired. The braking resistors are
supplied loose for customer mounting. The resistor bank should be mounted
within 50 feet (15 meters) of the drive enclosure. The cables to the resistor
bank should be in a single conduit with the positive and negative conductors
tied closely together, but not twisted. The positive conductor is connected to
the “+” side of the DC bus and the negative conductor is connected through
the thermal overload to the “-” side of the DC bus.
2-6
Losses and Ventilation/ The power losses experienced in the Drive are nominally less than 2 percent
Air Conditioning of the rated power. The Drive is air-cooled with air circulation provided by a
Requirements cooling fan. Since there is more than one INU on a common DC bus system,
the losses can be estimated by using 2% of each INU rating and adding them
together. This would be a worst case situation if all units were operated at full
load continuously. The 90 inch tall NEMA Type 1 enclosure requires no
clearance side to side, but does require a minimum of three feet in front of the
cabinet. The optional Fan and Filter kit requires an additional 14 inches of
height. A NEMA Type 12 cabinet requires a minimum of six inches of
clearance for the air conditioner to provide proper air circulation.
The ambient temperature of the installation site must be between 0C and 40C
(32F to 105F). In cases where restricted air flow or high temperatures are

Visually check that power cables are of the correct size and type and the
fuses are correctly sized to protect the wires from overloads and short
circuits.
. Check that shielded cables have been used for DC control circuits as
shown on the interconnection diagram.
. Check that control cables have been routed at least six inches from power
wires and that control and power cables do not have long parallel runs
and are run in separate conduit.
. Check that the power and signal grounds are properly connected. Refer
to section 2-5.1.
. Check that all packing material has been removed from the enclosures.
. Check that all contactors and relays operate freely.
. Check that cooling air is not restricted for each of the enclosure sections.
. Before connecting the power cables, check the cable insulation between
phases and from each phase to ground using a megger at 1000 volts for
the tests. Resistance must be greater than 1 megohm. Connect the
cables to the correct terminals per the connection diagram.
A CAUTION: DO NOT megger the drive, as damage may result!
9. Check that all terminal connections are correct and tight.
10.
11.
Check that there are no loose wires in the enclosure.
Measure the incoming supply voltage at terminals L1,L2 and L3.
Voltage must be at nominal rated voltage plus or minus 10% and each
phase voltage must be within + 5% of the other two phases.

Bulletin 1352 - 5.3 System
The following procedure should be used to start up a Line Generating Unit
(LGU). (Refer to Figure 2-3)
LGU DC
Disconnect
With the input power removed (main disconnect open), the LGU DC
disconnect closed, motors disconnected and all inverter (INU) DC
disconnects open check that the DC bus is at zero potential then check
the DC bus resistance of the LGU and each INU bus. A good measuring
point is at the disconnect terminals. The resistance should be
approximately 3000 ohms at each location.
The Line Generating Unit is equipped with a battery to backup critical
parameters including the fault queue and trend buffers. Because the
battery will only maintain the backup for approximately four days, the
battery is disconnected for shipment and must be reconnected prior to
startup. Jumper S3 on the 3500-CO3 Control Card must be switched to
position A-B to enable the battery backup. If battery is discharged it
may take as long as 20 hours to recharge.
Check that the DC bus disconnect is closed and the control power is on by
checking that the LED on the Power Supply Card is lit. Turn the “CTU
ON-OFF” selector switch (2S) to OFF. Close the CTU main disconnect
applying power to the AC bus. Press the “STOP” pushbutton on the LGU
control panel. Turn switch 28 to the ON position. Within 10 seconds the
main contactor will close. The LGU will not run. (This sequence verifies
the CTU logic).
If the main contactor closed (the desired result), press the “START”
pushbutton for the LGU. The LGU should run.
Refer to the Installation and Maintenance Manual 1352 - 5.0 for the
inverter for instructions to be followed prior to starting the inverter for
the first time. Closing the DC disconnect for the inverter applies DC
voltage to the bridge. An auxiliary contact on the disconnect supplies
AC power from the 215 volt bus.

LGU Adjustments Ina Line Generating Unit (LGU) there are many adjustment parameters as
well as four different modes of operation. All the parameters and modes of
operation are factory set for the specific application requirements. The
remainder of this section discusses the initial factory setup procedure to aid in
possible fine tuning during startup. For more details on the internal
operation of the LGU as well as an understanding of its various modes of
operation see section 4 of this manual,
The parameters used in the initial tuning of the LGU are detailed in
Table 2-2.

2-12.1 Current and Voltage Tuning - The current and voltage measurement
system has a number of adjustable parameters. Several of these adjustments
are actually carried out automatically by the drive system once the proper
flags have been set in the sequence detailed below.
The current measurement loop has two memory locations IUOFFSET
298EE and IVOFFSET 299EE whose contents may need adjusting to
acheive a proper current measurement. The initial value of each parameter is
16460. The adjustment is semi-automatic and takes place as follows:
1) Deenergize the LGU output by opening the main contactor (Turn
ON/OFF switch 2S to OFF).
2) Set parameter IOFFCONT 297EE to any nonzero value.
3) Wait a minimum of two minutes. Parameter 297EE will automatically
reset to zero when the adjustment cycle is complete.
4) After the adjustment is complete, the contents of the memory locations
should be written to EEPROM by opening the write protection lock
(EEROMLOCK 8 equal to any nonzero number, see 2-13).
The voltage measurement system has three adjustable parameters:
UCMSCAL 83EE scaling factor of the DC voltage measurement
UMSCAL 84EE scaling factor of the AC supply voltage measurement
UCUSCAL 81EE ratio of DC voltage and AC supply voltage.
The AC and DC scaling factors UCMSCAL 83EE and UMSCAL S4EE
should both be adjusted so that the control panel voltage display and the
readout of a voltmeter are the same. Any required change should be minor. If
the panel display is too high, the respective parameter should be increased.
UCUSCAL 81EE is semiautomatically adjusted when the LGU is running.

RAM Memory Battery Backup
UCUCONT 296 is set to any nonzero number by using the following
procedure:
Reactive current controller is ON (48EE not zero)
Reactive current reference value (IQREFG 27EE = 0)
Reactive current limit KQ 28EE set to 850 or greater to avoid limiting
the reactive current controller output.
DC voltage reference UCREFG 26EE is set over 1000 to prevent
reactive current consumption from AC line.
The adjustment takes approximately two minutes. When UCUCONT (296)b
1s automatically reset to zero the adjustment is properly completed. If
UCUCONT is still set to 1 the adjustment is still being executed. If the value
1s anything else, the LGU has discovered a problem. Codes are as follows:
BIT DEC MEANING
1 2 Reactive Current Controller is NOT On.
2 4 IQREF (219) is not equal to zero.
3 8 Reactive Current Controller is limited
4 16 Modulator has reached the high limit
5 32 STOP routine has been executed
When adjustments are completed, the contents of memory locations should be
written to EEPROM so they are saved when the power is shut down. Open the
write protection lock EEROMLOCK 8 by setting it to any nonzero number
(see 2-13). It is also recommended that the changed parameters be written
down on paper, a form is provided for this in Section 7.
After completing the adjustments and selections, this information must be
stored in the permanent memory. To do this, set parameter 8 to 1 and wait for
control panel CP1 to finish displaying “SA51” (Control Panel CP2 “Stored to
Backup”). Parameter 8 must be reset to zero. To further ensure no loss of
memory, and/or unauthorized tampering with adjustments, it is
recommended the CP1 lock input be jumpered “ON” by jumpering terminals
16& 8 on the 3500-T74 Card and switch S4 be set to A-C on the Inverter Unit
A2 - Control Card (3500 - CO3, 103 - CON).
CP1 Lock allows parameter viewing via the Control Panel, but prevents any
adjustment. Switch S4 disables writing to EEPROM when in position A-C.
This also prevents possible memory loss.
after power is turned off, and the unit has been verified as
A WARNING: These jumper changes should be made only
Voltage Free.
In addition to being able to save the software program and all drive tuning
adjustments to EEPROM, the drive is equipped with a battery (Ni CAD)
backup for the following items in RAM Memory:
Fault Words
Fault Buffers
Fault Messages
Trend Buffers
12 Programmable Values
To engage the battery backup, Jumper $3 on the INU Control Card (A2)
(3500 - CO3, 103 - CON) should be position A-B.

If the battery backup is not properly engaged or the battery is dead ,the
control panel will intermittently display SA56. Turning power OFF then ON
again is required to reset this message.
off while the jumper S3 is in position A-B. The jumper must be in
position A-C for storage, or the battery will drain in four days.
Battery will recharge when power is applied for approximately 20
hours.

Introduction
Information provided in section 3 of this Installation and Maintenance
manual is intended to provide maintenance personnel with an understanding
of the major hardware components associated with the 1352 drive.
The 1352 drive consists of the major hardware units in various configurations
as described in section 1-4. In this section, each of these general blocks will be
further detailed . A summary of the units and their abbreviations is provided
in Table 3-1 for reference. Refer to the specific hardware schematics provided
for your particular drive application and Section 1-4 to determine which
hardware configurations you have been supplied.

Contactor Unit (CTU)
The CTU performs the function of controlling the application of the 3 phase
input line power to the 1352 drive. The CTU is sized based on the total power
requirements of the application. The CTU consists of a main disconnect
switch, fuses, contactors and relays as shown in Figure 3-1. There are
basically two relay functions performed by the CTU relay logic. The main
contactor (K4) controls the application of three phase power directly thru the
CTU. This power is then applied to the LCU. A precharge relay allows power
to flow from two of the three phases on initial energization of the drive system
in order to precharge the capacitors located in the CBU.
When main disconnect S2 is closed, the Phase Loss relay K1 is energized and
power is supplied to the control transformer T2. The Phase Loss relay is
connected to the three phase supply immediately after the fuses and on a
phase different than the control transformer. This means that if one phase is
open, either K1 or T2 will be de-energized and the drive will shut down.
Transformer T2 provided 115 volt AC for the control circuit and 215 volt AC to
the Bus for control power to the other units in the lineup. If there are no faults
when power is applied, relays K2, K6 and K6A are energized and relay K5 is
deenergized. With K2 energized, bus pre-charge timer TR1 and contactor K3
are energized. Contacts from K3, supply single phase AC thru resistors R1 to
the line Converter Unit (LCU) which charges the DC bus Capacitor Bank
Unit (CBU). When TR1 times out it opens K3 and energizes the main
contactor K4 which applies full three phase line voltage to the LCU. The
setting for TR1 should not be reduced below 0.5 seconds to allow sufficient
time for the DC bus to charge. If the bus does not charge to a high enough
level, fuses F1,F2 and F3 may open when the main contactor K4 is energized.
Page 3-2
Bulletin 1352 5.3 System
Ifa CBU voltage imbalance occurs, relay K6 and K6A would energize which
would in turn energize relay K5 (CBU Fault) which seals in, de-energizing K2
and K4, thus shutting down the drive. The fault relay is reset by cycling the
E-STOP pushbutton or by opening the main disconnect S2.

The control circuit for the regenerative system is the same as the basic system
except that it has relays providing information from the Line Generating Unit
(LGU) as shown in Figure 3-3. Relay 2K indicates CTU ready and Relay 1K
indicates contactor enable. The two contacts are in series and must be closed
for precharge to occur (TR1 and K3 energizing). If either 2K or 1K open while
K4 is closed, TR1 will open which will open K4 and shut down the drive.

Line Converter Unit (LCU)
Figure 3-4 illustrates the hardware contained in the LCU. The LCU uses a 6
pulse diode bridge to convert the incoming 3 phase AC power to DC. The LCU
is equipped with a fan for cooling and a thermal switch to guard against
overtemperature. On 290KVA and larger units, the fan and thermal switch
have a manual switch (F51) in their circuits that is open when the unit is
shipped. This switch must be closed before the unit is started up to provide
power to the fan from the 215 volt AC bus and allow K2 in the CTU to close.
The DC choke is provided to filter the ripple from the diode bridge and along
with the CBU provide a smooth DC voltage to the inverters.
The RC snubber circuit in parallel with the diode bridge guards against
temporary overvoltages or voltage spikes by limiting the rate of change of DC
voltage. The bi-polar design reduces losses in the resistors during normal
Ul o
operation.

On units larger than 300 KVA, each of the capacitors is fused for protection.
These CBU's also have thermal switches for protection against
overtemperature wired into the K2 Fault circuit and a fan or fans for cooling.
The power for fans is provided from the 215 volt AC bus. Discharge resistors
R5, R6 and R7 are provided to balance the voltage across the capacitors and
discharge the resistors when power is removed. The resistors are sized to
discharge the DC bus to below 50 volts in one minute per NEMA standards,
but the voltage should always be checked before allowing anyone to work on
the unit.

A capacitor bank supervision card 3500 - CBS is provided on units 290 KUA
and larger to monitor the voltage balance on the capacitors. This signal is
used in the CTU K6 relay circuit to indicate an overvoltage. LED's are
provided to indicate if any section is below the minimum voltage, which would
then create a higher voltage across the other sections.
IMPORTANT: The LED's are not sensitive enough to assume that the DC
bus is discharged just because the LED’s are not lit. ALWAYS use a
voltmeter across the “+” and “-” terminals to check the bus level before
allowing anyone to work on the unit.

inverter Unit (INU) The INU converts the DC voltage from the DC bus output of the CBU to a
voltage and frequency controlled Pulse Width Modulated (PWM) waveform
which is then applied to the AC motor. Figure 3-6 provides an overview of the
major hardware components associated with the INU.
The Inverter Unit is described in detail in separate manuals. The Bulletin
1352 Installation and Maintenance Manual (1352 - 5.0) provides a basic
description and installation instructions. For a more complete description
‘and programming information refer to either Bulletin 1352 Vector
Programming and Operation Manual (1352 - 5.1) or the Bulletin 1352 Scalar
Programming and Operation Manual (1352 - 5.2) depending on the type of
inverters used in the system.
The one major difference with the inverters used as a part of the system is
they have a DC disconnect and fuses for isolation from the DC bus. The AC
control power is provided from the 215 volt AC bus and is controlled through
an auxiliary contact on the DC disconnect so that when the disconnect is
closed, AC power is supplied to the inverter.

Line Filter Unit (LFU) — The Line Filter Unit (LFU)is required on all systems that use a Line
Regenerative "front end”. The LFU provides the proper impedance which
makes controlled regeneration to the line possible, and also provides filtering
for the regenerated energy. The voltage feedback signal for the Line
Generating Unit is provided from the LFU through manual switch F71 (refer
to Figure 3-7). If these wires are ever removed it is important that they are
replaced on the same terminals since this signal is used to determine the
phase rotation information for the LGU as well as the AC voltage level. A
thermal switch is connected into the circuit of K2 in the CTU which will shut
down the system if an overtemperature condition exists. The LFU is force
ventilated with fans connected through a manual switch (F72) to the 215 volt
AC bus. The switch is also in the thermal switch circuit to shut down the
system if F72 is not closed. The switch is shipped in the open position and
must be closed prior to startup to allow K2 in the CTU to close.

The line Generating Unit (LGU) is best thought of as an INU that can be
operated as a generator supplying power to the line rather than to the motor.
The LGU must synchronize to the existing line voltage and return the power
from the motor back to the AC line. The LGU is described in detail in Section
4 of this manual.
With the 1352 Drive there may be an optional chopper controlled braking unit
(see Figure 3-8). The braking unit consists of a control card (3500 - BCC),
GTO, diode and thermal switch. The control card monitors the DC bus voltage
and provides the logic signals to control the GTO (V1). A voltage selection
jumper Sl is provided on the card to select the proper resistor to match the
voltage level. An LED V22 is provided to indicate that the bus is charged.
The card receives its power through resistor R3 from the DC bus. The GTO
controls the power to the braking resistors. When V1 is conducting, the DC
bus voltage is applied across the braking resistor BRR connected to terminals
R + and R-. During turn off, the inductive current from the resistor circuit is
returned to the DC bus via diode V2. The thermal switch F11 monitors the
temperature for protection and will shut down the system if an
overtemperature occurs. The braking resistors are protected against
overcurrent with a thermal overload in series with the resistors and shuts
down the system if an overload occurs.

Control Card has its operating voltages. It must not be considered
a safety indicator for servicing the braking system. The LED does
not indicate that all voltages have been removed from the circuit.
To guard against accidental contact with hazardous voltages,only
a DC voltmeter should be used to test for absence of voltages
before servicing any part of the drive or braking system.

Operating The Drive - Controlling Drive Operation is simplified by self
explanatory Display Buttons.
START & STOP are momentary pushbuttons to the drive.
LOC/ REM toggles between the local or remote frequency reference. Note the
“Remote” indicator light in the display which indicates if the drive is
— following the remote reference. Initial power up of the drive will be in the
local mode unless it is adjusted such as with Auto Restart.
REV Reverses the direction of rotation of the motor. This button is normally
defeated in software when shipped.
RESET is used to reset any fault. It also has another function when it is used
in the parameter mode (refer to section 3-9.4)
PARAM - Refer to section 3-9.4
DISPLAY - Refer to section 3-9.3
+ /- adjusts the local reference when in the operating (Normal) mode .
Depressing the “ +” button will increase the reference, “-” decrease it.
Response may appear slow since the adjustment initially is made to the
hundreth digit (0.01). Keeping the button depressed will speed up the change
as the adjustment digit will move to the tenth (0.10) and then to the “unit”
(1.00) digit. As you approach the desired value release then repress the button
to slow 1ts rate of change, See parameter mode (section 3-9.4) for additional
uses.
Display Operation - In the normal operating mode, pushing the display
button (Figure 3-9) will provide readings on:
- Drive Frequency References
- Output Frequency
- Motor Current
- Output Voltage
Pushing the display button will change from one display to the next.
The readings are identified by programmable code letters that appear after
the readout on the display .
Fifteen (15) programmable code letters are available for customer use. Five
(5) of the codes have been preset at the factory to indicate the following
readouts: (For additional information, see Publication 1352 - 5.2 Scalar
Programming and Operation).

Parameter Mode - The control panel is used for drive tuning and
troubleshooting. Parameters are effectively equivalent to the potentiometers
and test points in analog drives. Some of these values may need changing,
while others need to be viewed only. Viewing and changing parameters is
accomplished by following these steps:
1)
2)
3)
4)
Press the PARAM button.
The Display will read P__ 0001. Press “+” or “-” to reach the desired
parameter. Note the + and - buttons will change the value at an
accelerated rate similar to the description under Normal Operation.
Press DISPLAY to examine the value of that parameter.
To change the value, press “ +” or “=” to reach the desired value. Press
RESET to enter the new value into the parameter. The display will
automatically return to the normal mode if value is not changed.
Otherwise, pressing RESET will return the display to the normal mode
or PARAM to select another parameter for viewing.
IMPORTANT: For final parameter changes to be acknowledged and
stored in EEPROM, it is necessary to set parameter 008 (EEPROMLOCK)
to 1 before deenergizing the drive. When writing new values to EEPROM
memory, DO NOT interrupt power until the display acknowledges all
values are stored by the message SA51 disappearing from the display.
Many of the parameters have preset minimum and maximum values. Ifan
attempt is made to enter a value that is outside the range, SA53 will be
displayed on the panel. Entering a number that is within the parameter
range is necessary to clear the fault code. If an attempt is made to change a
parameter that cannot be changed, SA55 will be displayed then automatically
reset.
If you are unable to clear the fault in this manner, it may be necessary to cycle
power with the main disconnect switch.

CP-2 Control Panel
3-10.1
3-10.2
Description - The CP-2 Control Panel (Figure 3-11) is an optional panel used
for both DC and AC drives. It is used either on the drive cabinet, or remotely
mounted (Max. 300 feet). From the CP2 panel the drive can be controlled,
parameters set, faults and parameters displayed and functions programmed.
The panel contains 12 pushbuttons and a 16 character alpha-numeric display.
It also may contain 4 digital inputs (24 VDC or 115VAC) 4 digital outputs
(24VDC solid state) and one analog input. CP2 can be either flush mounted or
surface mounted. Refer to Figure 3-12 and 3-13 for dimension and cable entry
locations. All connections are made using the 48 pin terminal block X2 on the
Terminal Block Card at the bottom of the enclosure.
The panel is connected from serial channel 2 of the drive to serial channel 2 of
the CP2 panel. External power (24V, .5 amp) is needed for both transmission
and reception. The communication rate is set by means of jumper S2 on the
Terminal Block Card using pins 7 & 8 for 4800 Baud. The terminal points for
the VO circuits are shown in Figure 3-14.

Displays - The normal display on the CP2 control panel (Figure 3-11) has
three sections that are programmable. The default settings are:
Frequency Reference - Left Display
Frequency Feedback - Middle Display
Drive Status - Right Display
When a fault occurs the display is changed to display the fault message which
is a 16 character message describing the fault. For the list of faults refer to
Section 5.
Setting Parameters - Drive parameters can be displayed and changed from
the Control Panel. Pressing the PARAM key changes the display from the
default to displaying parameter addresses. In the parameter mode the CP2
will display the parameter address in the left portion of the display and the
parameter value in the right hand portion. To change the parameter
displayed, the follwing keys must be used:
+ or - Increments the parameter address by 1.
+ or —, then +/- Increments the parameter by 10
+ or —~ with +/- Increments the parameter by 100
To change parameter values, simply select the parameter to be changed, then
press the PARAM and VALUE keys simultaneously while depressing the +/-
and + or - keys to adjust the value. In this mode, pressing the +/- key
simultaneously with either the + or — key will increment the value in units of
1000 instead of 100. Parameters that cannot be changed will display
“ILLEGAL PARAM” when an attempt to alter them is made. Changing back
to the original displayed address will reset the message. If a parameter has a
value greater or less than the limits, the display will indicate “BAD PARAM
VALUE” and the limit will be entered into the parameter.
Scaling the Displays - The values shown in a standard display may be
scaled as desired. There are three parameters for scaling each display:
coefficient, divider and decimal point. The coefficient is the multiplier that is
used with the variable while the divider, as the name implies, is the divisor in
the formula. This combination determines the numbers displayed and the
decimal point is determined by the decimal parameter. The following is a list
of the display parameters:
PARAMETER FUNCTION
100 Speed Coefficient
101 Speed Divider
102 Speed Decimal Point
104 Current Coefficient
105 Current Divider
106 Current Decimal Point
The decimal point parameter with a value of 2 indicates that a decimal point
will appear to the left of the second least significant digit. As an example, to
scale a frequency parameter (.01 Hz. increments) to display in feet per minute
where 60Hz. equals 150FPM, the parameters could be set to the following
values:
PARAMETER VALUE
100 = 1 (coefficient)
101 = 4 (divider)
102 = 1 (decimal)
The frequency parameter would be 6000 (60.00Hz.) when the speed was
150 FPM. Multiplying by parameter 100 (1) gives 6000 and dividing by
parameter 101 (4) gives 1500. The value of parameter 101 determines that
there will be one decimal place and the display will show “150.0”.

Control Card
Installation - Normally installation of the CP2 panel is accomplished when
the drive is wired per the interconnection diagram provided with the drive. If
there is a desire to modify the installation, the connections for each of the
functions is described in this section.
Figure 3-14 details the pin numbers for each of the functions and the typical
connections that could be made.
Figure 3-15 illustrates the general layout of the Control Card. The basic
hardware on the control card (with the exception of software chips related to
LGU,Scalar or Vector control) remain the same on all drive applications.
Galvanic isolation of signals coming into the drive from external devices is
accomplished thru the use of a fiber optic serial communication link between
the Control Card and the I/O Cards. Devices V1 thru V6 provide for
connection of several fiber optic links. Only a few of the fiber optic
communication devices may be used depending on the specific application.
Power supply inputs come thru 20 lines of the 40 pin ribbon cable connected to'
connector X1. The other 20 lines of this connector are used for the gate pulse
signal output from the Control Card to the Pulse Amplifier (s) (and the GTO
Chopper Control card when used). Connector X2 is a 40 pin ribbon cable
connector which provides interface between the Control Card and the
Matching Card.
Connectors X3 thru X5 are used for current feedback information coming
from the Hall - Effect transducers. In the GTR units, only X3 and X4 are used.
In the GTO units, all three connectors are used.
Connector X6 provides for analog output signals from 4 Digital to Analog
(D/A) converters located on the Control Card. Because the Control Card is at
the DC Bus potential, the analog output signals are also at DC Bus potential.
Therefore, in order to use the analog outputs, an optional hardware
conversion unit, which provides isolation from the DC Bus potential, must be
used. |
The microprocessor (D8) carries out all functions on the Control Card with the
exception of fault tripping, which is a hardware function. EPROM chips (D17
and D18) contain the main operating program, and will be different
depending on the specific type of control being used (Vector ,Scalar or LGU)
and the firmware revision provided. In addition to the parameter information
stored in RAM (Random Access Memory), there are several parameters which
are related to set-up and configuration of the drive which need to be retained
in the event of a power loss. This type of memory is called EEPROM and is
contained in D16. If the power is lost, all critical drive set-up parameters will
be retained in this memory. In addition to the EEPROM backup, there is a
battery on the control card which maintains some of the RAM memory if
power is lost.
Jumper switch SI is used to set the baud rate for serial communication.
Position a- b corresponds to 9600 baud and a- ¢ corresponds to 4800 baud.
Switch $1 should always be in the a- € position. Jumper switch S3 is used to
disconnect the battery backup when the control card is in long term storage.
When S3 is in the a - b position, the battery back-up is operational; when in
the a - € position battery backup is disabled. During normal operation, S3
should be in the a - b position, and for long term storage, in the a - € position.
D4 controls the write-enable function of the EEPROM backup. When S4 is in
the a - b position, writing to EEPROM is enabled, when in the a - c position,
writing is disabled. If EEPROM writing has been enabled by S4, backup of
the drive set-up parameters is controlled in software.

GTO Pulse Amplifier Card
The GTO units require three Pulse Amplifer cards. Figure 3-16 shows the
Pulse Amplifier Card with the amplifier circuits for the two GTO's associated
with one phase of the output. A shared logic circuit produces gate control
signals for both GTO’s and ensures that the two devices associated with a
single output phase are not gated on simultaneously.
The gate control signals are sent to individual pulse amplifier circuits for each
GTO. Signals between the logic and the amplifiers are optically isolated. The
amplifier circuits then produce the gate signals for each GTO. In addition to
the gate signal, each amplifier circuit provides the short circuit monitoring of
the output of the inverter and protection of the amplifier circuit for each GTO
in the event of a shorted device.
In the event of a short circuit on the output, all GTOs are turned off. In the
event of a shorted device, the fuse associated with the individual device will
open protecting the amplifier circuit. The logic on the card also detects a
shorted GTO and prevents firing of the other GTO controlled by the card.
Feedback information pertaining to the actual state of each GTO is returned
to the control card and is indicated by an LED associated with each GTO.
During normal operation all LEDs should be lit, if a fault occurs the LED
associated with the affected GTO will not be lit.

The Chopper Control Card (Figure 3-17) controls the gating of the chopper
GTO. Energy from the commutation of the GTO's in the main inverter bridge
is fed back to the DC bus thru GTO V17. The amount of energy transferred is
determined by the duty cycle of V17.
Control logic on the Chopper Control Card receives a clamping capacitor
voltage reference signal from the Control Card which has been derived from
the Matching Card. This value is compared to the actual measured value of
the capacitor voltage by means of DC bus voltage and GTO terminal voltage
feedbacks. The error between the reference and feedback determine the duty
cycle of the chopper GTO and is used to produce a gate signal for the GTO
which is then amplified.
The amplifier circuitry is very similar to that used in the GTO Pulse
Amplifier cards. In addition to the gate signal, the amplifier circuit provides
for monitoring of the power supply and protection of the amplifier circuit in
the event of a shorted device. In the event of a shorted device, fuse F1 will
open protecting the amplifier circuit.

Auxiliary Power Card The Auxiliary Power Card (Figure 3-19) is used to provide + 300 VDC power
to the Power Supply Card. The +300 VDC is normally derived directly from
the DC bus. Upon initial power up, or if the DC bus voltage drops
momentarily, a secondary source of power provided to the Auxiliary Power

Input/Output Connection
Card
The Input/Output Connection card (Figure 3-20) is used to provide
interface between the control and external devices including discrete logic
control devices and analog signals in addition to serial communication and is
typically used for single drive applications. In addition, the card is also
capable of accepting tachometer feedback signals.
Jumper switches on the card are used to scale hardware on the card for the
rated voltage of the tachometer. S1 is used to select the power supply voltage
for the tach where a - bis +24VDC and a - с is + 13VDC. Switches S2 and
53 are used to scale the feedback circuit for the tach voltage used. Position
a - b for both S2 and S3 is used for + 13VDC tachs and a - ¢ is used for
+24VDC tachs. Jumper switch S6 is used to determine the type of signal
used for the discrete analog input coming into the card on X3 terminals 18
and 19. Position a- b scales the circuitry for current signals either 0 - 20 mA
or 4-20 mA and position a - ¢ scales the circuitry for voltage signalsof 0- +5
VDC.

CBU Supervision Card ~~ On Capacitor Bank Units of 290 KVA and larger, the voltage across each
individual segment of the capacitor bank is monitored for overvoltage
conditions. Monitoring is performed using the CBU Supervision Card. LEDs
on the card indicate the condition of the voltage level accross each capacitor
segment. Either 3 (460V) or 4 (575 V) LEDs will be used depending on
whether 3 or 4 capacitor bank segments are connected in series. Under
normal operation, there should be one LED lit for each capacitor bank
segment. If the voltage on a particular capacitor bank segment goes below the
limit value, the LED associated with the segment will not be lit, and a relay
circuit in the CTU is alerted to the fault.

Matching Card
The Matching Card (Fig. 3-22) is mounted on the A2 Control Card and 3500-
CO3 provides a matching circuit for the DC bus voltage and inverter phase
currents based on the KVA rating of the LGU and the rated voltage. Near the
center of the board are two selection jumpers S1 and S2 that set the rated AC
voltage. Unless otherwise specified, the jumpers are set to 460 volt.

BULLETIN 1352 LINE GENERATING UNIT
4-0
General
4-1
Theory
The Line Generator Unit (LGU) is used to supply power to the DC Bus feeding
the inverter units as well as regenerate excess power from the motors to the
AC line. The LGU hardware is the same as a Bulletin 1352 Inverter Unit
(INU) with the exception that it contains different firmware chips, matching
card, control card and IOC card. A Line Filter Unit (LFU) is always provided
with the LGU to provide reactance in the system.
WARNING: When voltage is supplied to the LGU a potentially
fatal voltage is present between the cards and the chassis. The
control card is at full DC Bus potential, and the leads running to the
matching card are at full line potential. Only qualified service
personnel familiar with the Bulletin 1352 should attempt to service
the drive or make measurements on the cards.
Due to the greater capabilities of the LGU in comparison to other regenerative
drives it may appear complex, but in reality it utilizes a less complex control
scheme than an INU. There are three functions of the LGU control scheme
when regenerating:
1) Controlling the active current
2) Controlling the reactive current
3) Maintaining synchronization with the line.
This is accomplished rather simply first when the regenerated power from the
motors increases, the frequency of the LGU attempts to increase. This
increases the phase angle between the LGU and the line thus producing more
active power to the line. The reactive power is determined by controlling the
voltage drop across the reactor in the (LFU).
The frequency of the LGU (Active Current Controller) is controlled according
to the voltage level of the DC bus. When a motor is driven by the load it
produces a higher voltage which is rectified by the inverter to DC and forces
the DC bus level higher. The LGU control maintains a fixed DC bus level by
increasing the frequency reference to the LGU as the DC voltage increases.
Since the output of the LGU is tied to the AC line, the frequency doesn’t
actually change, but the phase angle between the LGU and line changes.
Consider the phase angle as an adjustable valve, allowing more or less current
to be returned to the line to maintain the DC voltage at a constant level.
The reactive current controller is also relatively simple, in that it compares
the line voltage and the voltage from the LGU to maintain a fixed voltage drop
across the reactor in the LFU. Since the impedance of the reactor is almost
entirely reactive, the voltage drop across the reactor determines the reactive
current. Normally the LGU is adjusted to maintain zero reactive current, but
it can also supply reactive current to the line in the same manner as a
synchronous generator when it is overexcited.
Synchronizing the LGU to the line is accomplished by using the voltage
measurements and controlling the LGU starting point based on when the line
voltage crosses zero. The zero crossing point is then corrected for the time the
control takes for measurement, to accomplish a perfectly smooth start.

Operation

4-2.5
Besides Start and Stop, the LGU operation is virtually automatic and requires
little operator input.
General - Closing the DC disconnect and then the main CTU disconnect in
that order, connects power to the control card in the LGU. The microprocessor
on the control card then initializes and illuminates a red LED on the card.
The CP1 panel displays a status message after initilization is successfully
completed. Since the main contactor is open, there is an internal DC
undervoltage fault in the LGU as well as a chopper undervoltage fault. After
the contactor closes, the LGU attempts to reset these faults. The LGU does
not report that it is ready until these faults have been removed. With the first
START command, the firmware again executes a RESET command.
Main Contactor - The main contactor is interlocked with the LGU so that it
cannot be closed until the LGU indicates that it is ready. The main contactor
is controlled with an "ON - OFF” selector switch on the CTU enclosure door.
When the main contactor closes, it sends an interlock signal back to the LGU
to indicate that it is closed and starts the LGU.
Starting - The START command can be given from any of the control devices
used with the drive (CP1,CP2,PLC,DRC etc.). Normally the “ON-OFF”
switch on the enclosure is used for the start command. This command is sent
to the LGU control as well as closing the main contactors. When multiple
control devices are used it is important to use only one at a time since the
commands to the LGU can be overwritten if control is attempted from more
than one location.
IMPORTANT: Ifthe diode bridge mode is selected, the LGU may not start
immediately but will begin to monitor the DC voltage for start-up in the event
regenerative braking to the line is required. (Refer to Section 4-4.3)
Stopping - The STOP command can be given from any of the control devices
used with the drive. The "ON-Off” switch on the enclosure is normally used
for the stop command.
The EMERGENCY STOP pushbutton is a maintained position pushbutton
with a red mushroom head located on the CTU enclosure. This button will
open the main contactor in the CTU and remove power to the CTU control
circuit. An interlock between the LGU and the contactor shuts down the
LGU.
Automatic Restart - When the LGU stops due to undervoltage, overvoltage
or overcurrent the LGU is usually programmed to reset the fault and attempt
to restart. This operation is termed Rapid Automatic Restart (RAR). [f the
fault occurs again within 16ms of this first restart attempt, the LGU will
make a second attempt after a preset delay. This delayed restart is termed
Delayed Automatic Restart (DAR). If a third fault occurs within 16 ms of the
DAR, a third attempt is not made, instead the LGU is stopped and the fault is
reported on the control panel.
If the second (or third) fault occurs more than 16 ms after the previous fault,
the LGU makes a new RAR attempt. In order to eliminate excessively
frequent restart attempts, the LGU supervises the restart function by
limiting the number of RAR’s in a given period of time. Both the number of
restarts and the time period are adjustable. When an RAR or DAR is
successful, a diagnostic message will appear on the control panel indicating
the cause of the fault and if it was an RAR or DAR.

The microprocessor for the LGU comes with a built-in program for controlling
the LGU. This section will describe this program starting with a general
overview of the functions and then explaining how the functions are
developed. The Firmware Overview Diagram in Section 7 of this manual
shows the complete detailed diagram.
Reading Software and Firmware Diagrams - The software and firmware
diagrams for the INU and LGU follow similar arrangements. Each signal
reference and control section is labeled with a reference to the section of the
manual describing that portion of the diagram. Each section is composed of
various function blocks. The inputs to a function block are shown on the left,
outputs on the right. Other parameters affecting the function block are shown
above or below the block. Two examples are detailed in Figure 4-1.

4-3.2 Overview - The control circuit for gating the GTO’s of the LGU has three
basic functions as described in Section 4-1. The DC Voltage Controller
which modifies the frequency of the LGU; the Reactive Current Controller
that modifies the AC voltage and the Synchronization Control which is
actually a measurement function that inputs to the DC Voltage Controller.
An overall block diagram of the control is shown in Figure 4-2. The Reactive
Current Controller and the AC Voltage Controller are the two sections that
form the AC Voltage Reference (UREF). The Frequency Reference (FREF) is
formed by the DC Voltage Controller and reference functions being added to
the line frequency. The DC Voltage Reference Optional Functions are
separated since they may or may not be included in the system provided. The
numbers in each block indicate the sections in this manual that describe the
function.

DC Voltage Reference - The primary flow of the voltage reference (Fig. 4-3)
starts with UCREFG (26) through the MAX/MIN block and SELECT block to
the SUM block. The MAX/MIN block limits the value of UCREFG between
UCMAX (154) and UCMIN (153). The SELECT block is used to select either
the optional functions or UCREFG for the DC voltage reference. The Reactive
Current Trim is also an optional function. The optional functions are
presented in section 4-4 of this manual. The Active Current Limit Trim is
added to UCREFH (240). The operation of the Active Current Limit Trim is
discussed in Section 4-3.8. The sum of these signals is again limited in a
MAX/MIN block with the same limits as UCREFG. The voltage reference is
then sent to a RAMP block that limits the rate of change of the reference to
UCSTEP (155) so that the controller does not receive large step changes in the
reference. The values of UCMIN, UCMAX and UCSTEP are all in units of
.1% of rated (1000 = rated). UCMIN default setting is 900 (90%), UCMAX
default setting is 1200 (120%) and UCSTEP default setting is 10 (1% in a 4
ms. increment). The output of the ramp block then goes to the DC Voltage
Controller.

DC Voltage Controller - The DC voltage Controller (Figure 4-4) compares
the DC voltage reference UCREF (218) with the DC voltage feedback signal
UCACT (224) and this difference or DELTA is fed to the three controllers.
The “PD” controller is the primary controller. The parameters used for
computation are complex and are calculated by the LGU from the inductance
of the LFU (LLGU 65) and the capacitance of the CBU (CLGU 66). The
computational parameters are KDLLL (55) and KFLL (57) which have the
values of 98 and 1600 respectively. |
The “D” controller is only active during large changes in the DC voltage. If
the difference between UCREF and UCACT exceeds 10% of the rated DC
voltage, the “D” controller is active. The 10% values are determined by
UCDIFMIN (60) and UCDIFMAX (59). Again the gains are determined by
the inductance and capacitance of the system as well as KAA (71) and KII (72)
which are factory set at 600 and 180 respectively.
The “I” controller output is slight when compared to the output of the other
controller and its function is to bring the DC voltage error to zero. The gain of
the “I” controller is PUI (53) and is set at 500. The sum of these three
controllers is then limited to the range from -10000 to + 10000 which equates
to + or - 12.5 Hz. in the frequency control.
Frequency Controller - The output from the DC voltage controller is
summed with FNETWORK (204) to obtain the final frequency reference
FREF (220). FNETWORK is obtained from the AC line frequency FNET (86)
that has been limited to the range between FNETMIN (165) and FNETMAX
(166) with the rate of change controlled by FNETSTEP (167) in the ramp
block. The frequency values are scaled so that 48000 equals 60 Hz. FREF can
also be considered as the “active current” reference since the frequency
reference to the modulator is what determines the phase angle between the
LGU and the line voltage and thus controls the power returned to the line.

Reactive Current Controller - The Reactive Current Reference (Fig. 4-5)
can be used or bypassed as desired. If IQCONT (48) is set to zero, the Reactive
Current Reference is bypassed and DUSET (54) is used as the input to the AC
Voltage Controller. Both DUSET or the external reactive current reference,
IQREFG (27)are normally set to zero. IQREFG is clamped between the limits
IQMIN (156) and IQMAX (157) and its rate of change is limited in the RAMP
block by IQSTEP (158). The reactive current parameters are in .1% of rated
current (1000 = rated). The output of the ramp block is IQREF (219) which is
compared to the reactive current feedback IIMC (228). The difference between
the two goes to a “PI” controller. DUREFO (82) is the initial value for the
output and is automatically set to zero when UCUSCAL is calibrated as
described in section 2-8. The gain of the proportional part of the controller is
determined by PUQ (52) and is set at the factory to 4. PUQI (53) is the gain of
the integral part of the controller and is set to 400.

AC Voltage Controller - The AC Voltage Controller (Figure 4-6) includes

tries to exceed the limit, the output of the Reactive Current Controller is
reduced towards zero. After the LIMIT block, DUREF (222) is added to the AC
voltage feedback UACT (223) in the sum block and becomes the AC voltage
reference UREF (221) to the modulator.

Current Limit - The current limit for the LGU is accomplished in two steps.
Figure 4-3 shows the active current limit, and Figure 4-6 shows the reactive
current limit. The reactive current limit uses the active current feedback
IREC (227) and the total current limit KQ (28) to determine the reactive
current allowed. The reactive current allowed is determined by taking the
square root of the difference between the square of KQ and the square of
IREC.
Reactive Current allowed < V KQ2-iREC2 = V (P28)2 - (P227)2
If this value is exceeded, DUREF is clamped at zero. When not in current
limit, DUREF limit is calculated by the program using the rated voltage
(ULGU67), the rated current (ILGU 68) and inductance (LLGU 65).
The active current limit (Figure 4-3) is more direct using the active current
feedback IRE (231) and the active current limit setting KI (29). For this two
part current limit to operate properly, KQ (reactive current limit) must be set
to a lower value than KI (active current limit). In this way, the control will
reduce the reactive current to zero before having any effect on the active
current. Only if the current continues to rise after the reactive current is
eliminated, will the active current be reduced. When in current limit, active
current limit affects VCREF in such a way as to limit active current.
QUCMODE is not in effect and cannot increase the DC voltage to maintain a
set reactive current as described in section 4-4.4.

Modes of Operation
As seen in Figures 4-3, 4-6 and 4-7, there are five different optional features
that affect the way the LGU functions. They are factory set for the application
and require changing only during troubleshooting if it is desired to isolate a
portion of the firmware. Table 4-1 gives the default settings. A description of
the modes is provided in this section.

non-zero number it modifies the DC voltage reference according to the active
current feedback IREC227 (see Figure 4-7) This mode of operation is only
used when there is more than one LGU on the DC bus. The purpose of
PUCMODE is to let the DC bus voltage reference droop for this LGU when it
is providing more than its share of the power, thus keeping the load shared
between LGU's.

This load sharing is accomplished by comparing the active current feedback
signal IREC to several preset limits. The output is determined via a
programmable function block that defines five points on the curve.
The preset limits and the corresponding output are identified as:
INPUT OUTPUT
PARAMETER DEFAULT PARAMETER DEFAULT
IREC1 272EE -1000 IUCREFOFF1 130
IREC2 274EE -850 [UCREFOFF2 111

IREC5 280EE + 850 IUCREFOFF5 29
IREC6 282EE + 1000 IUCREFOFF6 10
The function block provides the curve as shown in Figure 4-8. Asan example,
if IREC is zero which is midway between IREC3 and IREC4 the output will be
midway between [IUCREFOFF3 and IUCREFOFF4 which is 70. The output is
proportional to the input within a given range. This would be similar to the
control being able to select points from the graph.
The output of this function block is then summed with the DC voltage
reference bias UCREFBIAS 284EE to form UCREFOFFSET 244 which goes
into the DC voltage reference circuit. For UCREFOFFSET to have any effect
either DBMODE 90EE or UCREFMODE 160EE described below must also be
selected as shown in Figure 4-3. If PUCMODE is not selected,
UCREFOFFSET is determined by UCREFOFF93.

UCREFMODE 160EE (DC VOLTS A FUNCTION OF AC VOLTS) -
UCREFMODE adjusts the DC voltage reference to AC line voltage changes
as well as allowing the voltage droop from PUCMODE as shown in Figure 4-3.
When UCREFMODE is set to any non-zero number it selects the sum of
UCREFOFFSET as described above and UACTDISP 203, which is the filtered
AC voltage feedback, as the intermediate DC voltage reference UCREFH 240.
When UCREFMODE is zero, UCREFG 26EE is used for UCREFH.
DBMODE 30EE (LGU OPERATES IN REGEN ONLY) - When DBMODE
is set to a non-zero number it will also select the DC voltage reference in the
same manner as described previously in UCREFMODE. DBMODE is selected
when the LGU operation is only desired while power is being regenerated
back to the AC line (Figure 4-9). This mode is used when an LCU is used in
parallel with the LGU. With an LCU in parallel and DBMODE not selected, a
circulating current of less than ten percent is flowing between the LGU and
the LCU when the power flow is from the AC line to the DC bus. With
DBMODE selected the LGU only operates when the power flow is from the
DC bus to the AC line, thus eliminating this circulating current. In
DBMODE the LGU is ready to run and monitors the DC bus level. When the
DC level exceeds UCDBMSTART 238 or the rate of rise of the DC bus voltage
is greater than DUCDBMSTART 239, the LGU will start and regenerate the
power back to the AC line. The LGU will stop operation when the filtered
active current feedback IREFF 235 is greater than DBMIRESTOP 79EE for
the time set in DBMCNTR 80EE (4ms increments).

QUCMODE 161EE (Maintain Power Factor via DC Volts) - The fourth
mode of operation is QUCMODE which will adjust the DC voltage reference to
maintain a reactive current setting (Figure 4-3). The reactive current is
determined by the voltage drop across the LFU reactor. During regeneration,
if the DC voltage is too low, then the LGU AC voltage will also be low and the
voltage drop across the reactor will be low (or negative) thus taking reactive
power from the AC line. When QUCMODE is set to any non-zero number, the
DC voltage reference is incremented up or down as a function of the reactive
current. Reactive current control must also be selected (IQCONT 48 not zero)
for QUCMODE to have any effect.
IQCONT 48EE (Select Power Factor Control) - IQCONT (48) is described
in section 4-3.6 and selects the Reactive Current Controller. This mode is
turned on by setting IQCONT to any non-zero number. When this mode is
inactive (IQCONT = 0), the reference offset to the AC Voltage Controller is
set to zero via DUSET (54).

START-UP “SECTOR” The start-up angle is adjusted only after all the measurement adjustments
ADJUSTMENT have been executed and only if over or undervoltage trips occur during
LGU startup.
The AC supply voltage period of 360° is divided into 60° sectors. (See Figure
4-10) Each sector begins at the instant one of the phase voltages crosses zero.
When the LGU is requested to start, it waits for one of these zero Crossings
before initializing.

SECTOR
Figure 4-10. Start-up Sectors
When the LGU begins a start-up routine, it checks the level of the line voltage
and the direction of rotation. If the line voltage is not present or too low, a
failure is displayed. If the level of line voltage is sufficient, the LGU defines
the next allowed start-up sector in which a start-up takes place. In defining a
start-up sector the LGU takes into account filtering delay of the AC supply
voltage measuring (approx. 18°) as well as a processing delay caused by the
synchronization routine. This delay time is stored to the memory location
FILTDELAY 92EE. Parameter 92EE scaling is 256 corresponding to the
angle of 60°. An adequate value is the initial value of 240. Changing this
value is generally not required.
The line synchronization is determined by measurement of two phase voltages
and comparing this to the calculated value. A comparison takes place after
performing each measurement. If the latest measured voltage is WV phase
voltage, the start-up mode is 1. When the UV phase voltage is measured, the
start-up mode is 2. The above ratios should be of a slightly different value
depending on the mode of start-up. The startup mode is recorded in
Parameter STARTMODE 342. The startup sector is recorded in Parameter
STARTSECT 341.
Start-up can be enabled or disabled for each sector and mode of start-up
separately. This is done by using memory locations 361EE, 364EE, 367EE,
370EE, 373EE and 376EE in the U-W-V case. The value of the first location is
sector 0 and so forth. Ifthe valueis 0, start-up in this sector is prohibited.
When the value is 1 only mode 1 is enabled, if the value is 2, only mode 2 is
enabled, and if equal to 3, both modes 1 and 2 are enabled.
Page 4-15
Bulletin 1352 5.3 System
The direction of AC supply voltage rotation is observed in the memory
locations DIREC 237 and UVWDIR 340. DIREC 237 is determined by the
direction of rotation when the LGU is not running and UVWDIR 340 when
the LGU is running. Both are automatically set. The 0 value corresponds to
the U-V-W direction and any non-zero corresponds to the U-W-V direction.
For U-W-V voltage rotation, contents of memory locations 36 1EE to 378EE
should be used. Rotation UVW uses 343EE to 360EE. The contents of the
memory locations correspond to each other in direct numeric sequence. (i.e.
343EE would be replaced with 361EE) Refer to Table 4-2.

When 343EE = 3 sector 0 start-up enable is set to 3 and start-up in any other
sector is disabled, i.e. 346EE = 349EE = = 376EE =0. A START command is
then given. If a start-up takes place too late, the content of memory locations
344EE and 345EE have to be changed to lower values. Refer to Table 4-3. A
good practice is to change content of both memory locations to the same extent
(e.g. decrease by 2). The total change should not be more than 10.

Unless DBMODE is being used, only one sector must be set up. When
DBMODE is used, all sectors should be set up since the DC voltage is
increasing and the startup should be immediate and not waiting for the next
cycle. When start-up of section 0 is adjusted (two start-ups are successful) the
content of memory location 343EE is set to 0 and the adjustment of sector 1 is
performed setting 346EE to 3. In order to perform fine adjustment, memory
locations 347EE and 348EE are used. The procedure is the same as above.
When adjustment of sector 1 is accomplished, an adjustment of sector 2 is
performed by setting 346EE to 0 and 349EE to 3 and so on. When sector 5 has
been adjusted, all sectors are turned on by setting the content of memory
locations 343EE, 346EE,..., 358EE to 3. After that, several start-ups should
be performed. If one start-up causes voltage trips, the start-up sector which
requires tuning can be obtained from location (341) and the mode of start-up
from location (342).
When the U-V-W rotation is properly adjusted, the adjustment of U-W-V
arrangement can be performed by changing two of the incoming lines to the
Line Contactor Unit (on the mains side!). The adjustments are performed the
same as above with the exception that different memory locations are used,
and if a start-up takes place too late (DC voltage increases), fine adjustment
parameters should be increased.
When the AC supply phase arrangement is known an adjustment for the
opposite phase rotation can be omitted. The start-up enable values of the
adjusted sectors are set to a final value of 3 and others to 0. The phase
arrangement should be determined at the installation site and checked that
the start-up enable values of the opposite arrangement are set to 0. The
parameters obtained should be stored in EEPROM memory by unlocking
EEROMLOCKS (8 =0) per section 2-13.

Operator Interface
4-6.1
The Bulletin 1352 Drive System is often connected to a master control such as
a Digital Reference Control, a PLC, a CP1 or CP2 control panel or the Drive
Maintenance System.
CP1 Control Panel - The CP1 control panel is mounted on the drive
enclosure and is used as the local control forthe drive. The description of the
CP1 is located in section 3-9 of this manual. The pushbutton status is sent
from the CP1 panel to the control via serial communications channel 1 using
Parameter CP1IBUTTONS 19. This packed word is the input to the function
block CPIBUTTONS which takes the packed word and provides a logical
output at the parameter addresses shown in Figure 4-11A. These addresses
are then used as the input for other function blocks that then go to the
SCALAR block. Serial channel 1 is always used for the CP1 panel.
The displays for the CP1 panel for the LGU are preset at the factory but can be
modified as required, the default displays are:
LETTER DISPLAY # DESCRIPTION
A DISPLAYO LINE CURRENT
r DISPLAY1 DC VOLTAGE REFERENCE
U DISPLAY 2 LINE VOLTAGE
с DISPLAY3 DC VOLTAGE
A DISPLAY4 LINE CURRENT
The display blocks are shown in Figures 4-11 (B) and (C). DISPLAYO block is
used to display the Line Current as a default. Parameter OUTO 1574 is the
value of the parameter before any display scaling. Parameters MIN 1682 and
MAX 1683 are the minimum and maximum values allowed for OUTO.
The other parameters are common to each of the display blocks. SP 1577
determines the rate of change of the display as follows:
SP = 0 only the parameter display functions appear
SP = 1 very fast change
SP = 2 fastchange
SP = 3 normal change
SP = 4 slow change
Page 4-18
Bulletin 1352 5.3 System
DISMARK is the parameter that determines the code letter used to indicate
the display that is shown. Display characters and the numbers used to select
that character are shown below:

L 0
r 1
[] 2
с 3
d 4
A 5
C 6
F 7
H 8
L 9
P 10
U 11
u 12
b 13
h 14
Parameters MUL, DIV and POINT are additional scaling factors for the
displays. MUL and DIV are the multiplier and divisor that are used to
convert the parameter value to a meaningful display.
DISPLAY to DISPLAY4 use D_ SOURCE as the address of the displayed
parameter rather than OUTO as is used for DISPLAYO. OUTO can be used as
the input to other function blocks, whereas D_ SOURCE cannot.
D__ SOURCE can however display any parameter from the drive.
SPECIALDISPLAY is used to display faults 25 and 26 as well as the
remote/local dot. For all three of these displays, any non-zero input will cause
the predetermined message to display, see Figure 4-11 (D). The fourth input
to this block is CP1LOCK which will disable parameter changing if 1356 is
any non-zero value.

Serial Communications Software - The serial communications uses many
parameters to define the data to be sent, how often and if the data was
transferred correctly. For connection to other communications devices the
communications specifications are:
Asynchronous serial data communications
Full duplex
Baud rate of 4800
Each word is 10 characters
Even parity
1 start bit
7 data bits
1 stop bit
The following are some of the communications parameters.
[МАГ and IX Parameters - A series of parameters from 114EE to
151EE are used to define the data to be transmitted on the serial channels and
the intervals at which the transmissions are made. There is room for up to
eight parameters (IXO to IX7) to be sent on channel 1 and eight more (IX0-2 to
[X7-2) on channel 2. The frequency of the transmissions is determined by the
intervals set in IVALO to IVAL7 for channel 1 and IVALO-2 to IVAL7-2 for
channel 2. The intervals are supervised to ensure that the intervals specified
will not overload either channel. Each transmission takes approximately 21
ms so that the more parameters to be transmitted, the longer the interval
required between updates of a given parameter.
Âs an example, consider the situation for channel 1 where parameter 247 is
sent every 210 ms, 248 every 189 ms, and 211 every 168 ms. The values in
each parameter are :
PARAMETER VALUE MEANING
114EE IVALO 10 210ms.
115EE IX0 247 Digital Output DIG__ OUTPUTS
116EE IVALI 9 189 ms.
117EE IX1 248 Analog output ANAOUTO
118EE IVAL2 9 . 189 ms.
119EE 1X2 249 Analog output ANAOUT1
120EE IVAL3 8 168 ms.
121EE IX3 211 FAULTWORDI
TBCTRANSMITI1 9EE and TBCTRANSMIT?2 10EE - The 3500 - IOC card
can be programmed to transmit input signals using a transmisssion buffer
with nine fields. Eight of these fields can be programmed with hexadecimal
code numbers, the first four fields are defined in parameter 9EE and the
second four are defined in parameter 10EE. The codes are as follows:
0 = No transmission
1 = Send analog input 0
2 = Send analog input 1
3 = Send analog input 2
4 = Send digital inputs
5 = Send CP1 push button signals
For example, assume that the analog input 0 should be sent every other time
and the other inputs are sent evenly. The transmission buffer would be 1-2-1-
3-1-4-1-5. Parameter 9EE would be set to 1213H and parameter 10EE would
be set to 1415H defining the last four codes. To enable the transmission,
parameters 9EE and 10EE would then be selected for transmission using one
of the communications parameters from 114EE to 129EE for channel 1 or
Page 4-21

134EE to 151EE for channel 2. If the communications were set as shown in
section 4-6.2.1 the addition of 9EE and 10EE would start at 122EE as follows:
PARAMETER VALUE MEANING

124EE [VALS 100 2.10 sec.
125EE 1X5 10 TBCTRANSMIT2 10EE
REQUESTMSGE 112EE and ANSWERMSGE 113EE - Parameters
112EE and 113EE are best considered as windows where data is passed from
the drive program to the external control device such as a control panel, DMS,
PLC or computer. For ease of explanation. assume a CP1 control panel is used
to change a parameter value. When the CP1 requests a parameter it sends the
parameter number to parameter address 112EE. The program then retreives
the value of the requested parameter and places that value into parameter
113EE to be sent to the control panel. If the operator changes the value of the
parameter at the panel and enters it into the program, then address 113EE is
sent to parameter 112EE which tells the programs to send the new value to
the last address requested. Parameters 112EE and 113EE are used by both
serial channels.
COMMUNICATIONS DIAGNOSTICS - The serial communications
channels are supervised and parameters are provided to store the information
necessary to check on the accuracy of the communications. The following isa
listing of the diagnostic parameters and a brief description of what they mean:
COMM __ TIMEOUTZ2 169EE Defines the maximum time between
messages before a channel 2
communications loss is detected.
CH2 BAUDRATE 170EE Determines the rate of data transmission
and must remain at 4800 Baud.
SELMACONT 171EE Determines the program action after
communications loss using the following
codes:
0 = No action
1 = Send message to Panel
2 = Send message plus ramp to stop
3 = Send message plus coast to stop
COMM__ TIMEOUT 172EE Defines the maximum time between
messages before a Channel 1
communications loss is detected.
OKMSGES1 182 À count of the completed messages on
channel 1.
FAULTMSGES1 183 À count of the lost messages on channel

BULLETIN 1352 TROUBLESHOOTING
5-1
General The Bulletin 1352 Drive has several advanced diagnostic and troubleshooting
functions available, including trending and the capability of reviewing prior
fault occurances. Troubleshooting procedures should begin by recording
information from the following sources:
Fault messages from the control panel
Faultword0 - Parameter 210 and Faultword 1 - Parameter 211
Status of LED's on the various cards.
DRIVESTATUS - Parameter 214
SCSTATUS - Parameter 215
5-1.1 Test Instruments and Tools - The following test instruments and tools are
required for fault tracing and repair:
A. Multimeter capable of 1000VDC/750VAC, with input resistance of at
least 1 megohm.
B. Testleads
C. Assorted (Phillips and Blade type) screwdrivers
D. Setof metric box-end or open-end wrenches or sockets, sizes 5-1/2, 7,
10, 13, 17, 19 and 24 mm in particular.
E. Soldering iron suitable for use with CMOS circuits ( grounded tip) and
solder.
5-1.2 Principle of Fault Tracing - The fault tracing method presented here is
based on systematic tracing of the fault location and then systematic testing
using spare circuit cards. For most fault conditions, replacement of control
circuit cards will isolate the problem in the shortest period of time. The fault
tracing method assumes that only one fault has occurred at a particular time,
possibly causing further effects such as blown fuses.
5-1.3 Documenting Errors - Any problems should be written down and
documented as to the failure, any indicator or fault messages that are
annunciated as well as the corrective action. This information will assist in
correcting any problem that re-occurs.

Testing Methods
5-3.1
A
WARNING: Servicing energized industrial control equipment can
be hazardous. Severe injury or death can result from electrical
shock, burn, or unintended actuation of controlled equipment.
Recommended practice is to disconnect and lock out control
equipment from power sources, and confirm discharge of stored
energy in capacitors, if present. Ifitis necessary to work in the
vicinity of energized equipment, the safety related work practices
of NFPA 70E, Electrical Safety Requirements for Employee
Workplaces , must be followed.
Do not remove the aluminum and plastic protection panels
needlessly during fault tracing. This is usually unnecessary and
can expose the personnel to potential hazards from voltage sources
present in the unit. Always replace protective panels before
operating unit.
In order to avoid damage to the CMOS circuits from an accidental discharge of
static electricity, the following rules must be followed when handling the
circuit cards and performing measurement checks on the cards:
A.
Before removing a card from the rack, discharge your own static
Charge by touching an unpainted point such as on the rack. The use of
a properly grounded wrist strap is recommended when performing any
checks or tests on cards.
A
CAUTION: The CMOS circuits utilized on the control eircuit
cards can be destroyed by static charges generated by friction of
materials made of synthetic fibers. Use of faulty circuit cards may
also damage related components.
When configuring jumpers or checking a detached circuit board, it
should preferably be laid on a conductive, grounded surface, taking
care not to short out the battery leads.
Test measurements on the control circuit cards are not permitted.
A
CAUTION: Do not perform measurements to any points on the
card. Such measurements could damage circuit components.
D.
DO NOT connect the common terminal of test instruments operated
from the main supply to the common terminal (M) of the auxiliary
voltage (+ 12V) unless power to the Drive is disconnected.
The probe of the test instrument can be moved from one test point to
another while the Drive is operating, provided that the probe is first
grounded by touching it to the common probe of the meter or scope.
Choosing the Right Fault Tracing Instruction - The following paragraphs
match the fault situations that constitute the starting points for fault tracing.
In some cases, operating personnel will have to reset the fault and then
attempt to restart the unit. The fault tracing procedure should start at the
point corresponding to the original fault indication. Occasionally, the cause of
a malfunction of the unit must be determined without any visible LED fault
indications.

Diagnostics - There are four sources of diagnostic information available to
the operator. This information is accessable via the local control panel and
can be transmitted via the serial communication link as bit coded words.
The sources are:
1) Fault Words (See Tables 5-1 thru 5-3 for summary and Sect. 5-3 for
details).
2) Fault Queue
3) Drive Status Word
4) Regulator Status Word
Fault Queue - In the event of a fault, the fault that occurs first is stored in a
buffer FLT _ QUEUE 176. This location retains the data until the drive is
reset. After being reset the fault code is moved to Parameter (177) and a
negative 1 is stored in Parameter (176). If power is turned off , this data is
backed up with a battery. If another fault occurs, all the data stored is moved
to the next higher memory location and the new fault number is stored in
Parameter (176).
Assume that the drive has had three fault shutdowns, the first from
overcurrent (05), the second from overtemperature (04) and the third from DC
Undervoltage (07) as the initial causes of shutdown. After each fault, the
drive was reset. The fault queue would contain the following:
PARAMETER FAULT # EXPLANATION
176 -1 RESET
177 7 DC UNDERVOLTAGE
178 -1 RESET
179 4 OVERTEMPERATURE
180 -1 RESET
181 5 OVERCURRENT
Drive Status - The status of the drive is summarized in the Bit Word found at
Parameter 214. The meaning of that word is decoded as follows:
BIT #
NOT RUNNING 0
READY 1
FAULT 2
Regulator Status - The status of the Drives internal regulators are indicated
by the bits in Parameter 215. The bit meanings are:
BIT #
QUIESCENT STATE 0
RIDE THROUGH 1
FLYING START 2
FREQUENCY INTEGRATOR 3
IREHIGH CONTROLLER 4
IRELOW CONTROLLER 5
UCHIGH CONTROLLER (119%) 6
UCHIGH CONTROLLER (116%) 7
IR COMPENSATION 8
IR COMPENSATION 12
TORQUE REGULATION 13
IR COMP AT CURRENT LIMIT 14
Faultword - The FAULTWORD parameters contain the fault codes and
status messages. All 32 codes are packed into the three faultwords as shown
in Tables 5-1 thru 5-3. The faultwords can be sent via serial communications
to the control devices (PLC ,DMS, etc.) A “1” in the bit indicates that the fault
has occurred. If multiple faults are present, the number displayed would be
the total of the decimal values of each fault.

Trends
5-5.1 General - The Bulletin 1352 LGU control software contains 8 sampling
buffers each with 100 sample capacity. These Buffers can be used to store
measurement data to aid in troubleshooting.
A sampling interval can be selected which corresponds to time interval
4ms ...262 seconds per sample by adjusting the number in parameter
TRENDIVAL 196. The time interval is the TRENDIVAL times 4ms. Scalar
control uses 3ms intervals rather than 4ms.
Triggering the storage (as explained in Sect. 5-5.2.3) can be done one of three
ways:
On a fault
Based on the value of Trend 1
Manually
5-5.2 Use of Trend
5-5.2.1 Selection of Monitored Addresses - Set a desired parameter number for
the trend control addresses which are going to be used. The default parameter
selected for the LGU is shown in the table below.

steps at 196EE.
196EE 01 = 4mssampling interval
2 = 8mssampling interval
3 = 12mssampling interval
3-5.2.3 Selection of Triggering Condition -
ÓN FAULT: A trend triggering occurs on an operation fault by setting
Parameter 197EE to -1. In this case trend triggering stores 80 samples before
the fault and 20 samples after.

Triggering From TRENDTRIG (197) or TRENDSAVE (199)
MANUALLY: A Triggering can also be accomplished “Manually” by using
single step mode in the same manner as an oscilloscope by setting 199
(TREND__SAVE) #0. In this case trend triggering is instantaneous and 199
is automatically reset to 0.
Monitoring of the Trend Triggering - The content of the memory location
TRIGCOUNT (200) is increased by one every time a trend triggering occurs.
Trend Content D/A Conversion - An analog signal can be obtained since
each trend buffer has an address which can be used for connecting a D/A
converter to a buffer.
The addresses are:
320EE Trend buffer 1
321EE Trend buffer 2
322EE Trend buffer 3
323EE Trend buffer 4
324EE Trend buffer 5
325EE Trend buffer 6
326EE Trend buffer 7
327EE Trend buffer 8 `
The sample conversion interval is 20ms/sample and the entire buffer content
conversion lasts 2s. This rate is sufficient for plotter operation. Each sample
contains a synchronization mark which serves for identification of trend’s
start point.

Bulletin 1352 Digital A.C. Drives feature printed circuit boards
that require no adjustments as part of the normal troubleshooting and
maintenance. This feature also helps simplify board replacement.
Circuit Board Replacement - The following steps should be followed when
changing the printed circuit boards:
CAUTION: The CMOS circuits utilized on the control circuit
cards can be destroyed by static charges generated by friction of
materials made of synthetic fibers. Use of bad circuit cards may
also damage related components. Observe proper care and
recommended practices when handling circuit cards.
A. Remove power by opening the disconnect switch and verify with a meter
that all circuits are voltage free.
B. Carefully detach all ribbon cables , noting their location and orientation
and whether the connectors were properly seated.
IMPORTANT: A grounded wrist strap should be used when replacing circuit
boards to protect against static discharge damage to the boards!
C. Remove the small metric mounting hardware with a screwdriver taking
care not to drop any of the associated washers into the other circuits of
the drive.
D. Lift out the circuit board in question, and check that the replacement
board is correct before attempting installation. Install the new circuit
board by replacing the mounting hardware and re-inserting the
connectors and switches in their correct location on the new board.
Steps A thru D apply to replacement of all printed circuit boards in the
Bulletin 1352 drive.
Control Card (103 CON/ 3500 C03) Replacement - In addition to the steps
mentioned above, the Control Card of the drive requires the transfer of the
following components when changing cards:.
A. Transfer EPROMS D17 and D18 to the corresponding locations on the
new Control Card using an I.C. removal/ insertion tool for CMOS
Circuits.
B. In order to retain the application software values, it will be necessary to
also transfer EEPROM D16 to the new card.
Page 5-21
Bulletin 1352 5.3 System
IMPORTANT: If the new empty EEPROM is left in the control card, it is
important that you observe item “D” when first reapplying power
C. Transfer the matching card and it’s spacers from the suspect board to the
new control board by removing the four mounting screws from behind
the card and re-installing them in the proper location on the new card.
Be sure to attach the X-2 connector firmly into its socket and latch the
connector tabs.
D. When reapplying power to the Bulletin 1352 after installing a new
control card, you must wait at least 2 minutes after the red LED on the
control card lights before interrupting power or adjusting parameters. If
you choose to use the new EEPROM (D186) which was supplied with the
card, it can take as long as 3 or 4 minutes before the LED lights.
After the LED illuminates, it is permissible to proceed with adjusting the
parameter values and operating the drive
5-7
Checking and Replacement When testing power semiconductors, the measurements must be made with
of Power Semiconductors multimeter that uses a sufficiently high current for resistance measurements.
Always determine the polarity of your instrument leads when performing
resistance measurements.
5-71 Power Transistors (GTR) - If it is suspected that a damaged GTR power
semiconductor device exists, proceed as follows:
® Before proceeding, verify that the drive is voltage free.
e Disconnect motor cables
® Disconnect card terminals of power devices
e
Measure the collector to emitter and collector to base resistances
(positive probe in contact with the collector lead). The resistances
must be different from those in the short circuit state (the resistance
value depends both on the ohmmeter used and the semiconductor
device itself). Generally, this is a resistance greater than 10k Ohm.
e Reapply voltage to the drive.
WARNING: Hazardous voltages will be present in the drive
when performing the following tests!
e Allow sufficient time for the intermediate circuit to charge up to `
measurement voltage. Switch the meter for a voltage measurement
and check the offset voltage of the diodes between base and collector
and emitter and collector (anode in contact with first mentioned lead)
values should be approximately 0.3V to 0.5V.
5-7.2 GTO and Free Wheeling Diodes - If a damaged or malfunctioning GTO
power semiconductor or Free -Wheeling Diode is suspected, proceed as follows:
® Verify that all the Drive is voltage free before proceeding.
® disconnect motor cables
® disconnect card terminals of power devices
e
Measure the collector to cathode, anode to gate, and cathode to gate
resistances (positive probe in contact with the first lead mentioned).
The value must be different from those in the short circuit state (the
resistance value depends both on the ohmmeter used and the
semiconductor device itself). Check the diodes by measuring
resistance between the cathode and anode.
e Reapply voltage to the drive.
Page 5-22
Bulletin 1352 5.3 System
5-7.3
when performing the following tests!
A CAUTION: Hazardous voltages will be present in the drive
Allow sufficient time for the DC Bus circuit to charge up to measurement
voltage. Switch the meter for a voltage measurement and ensure that
diode junctions exist between gate and the cathode (positive on gate).
Offset voltage should be approximately 0.5V. In the voltage range
measure offset voltage of diodes anode to cathode. If a damaged free-
wheeling diode is suspected, both the diode and thyristor will have to be
removed from the heat sink since they are connected in parallel. Remove
the thyristor by opening its clamp, and measure the diode condition.
NOTE: It is impossible to accurately measure the condition of the
thyristor when it is unclamped!
If the short circuit has been located, the semiconductor device must be
replaced.
Remove power from the drive,measure DC bus for 0 volts and remove the
bad semiconductor. If necessary, also detach the conductor busbar
positioned across the semiconductor as well as any associated leads. Note
the direction in which the device was originally installed. This will
ensure correct polarity when a replacement semiconductor is installed.
IMPORTANT: GTO devices must be replaced with the same
manufacturer’s device. Verify the correct type from the vendor part
number printed on the insulator portion of the device. Recheck the
clamping value for the new GTO.
Installation Instructions - Power semiconductors are precision devices. New
semiconductors should be stored in their original packages until required .
NOTE: To avoid confusion with “good” components, always clearly mark
suspected damaged components after removing them from the circuit.
A.
When replacing components, check that the new and old components have
the same type designation or that the new component can replace the old
one. At this stage, review the phases of the replacement procedure and
consider orientation of the heatsink. Care should be taken to assure
proper clearance between heatsink components to reduce possibility of
arc-over when voltage is applied to the Drive.
Preparation of the heatsink and busbar:
If the area is clean, spread out the remaining heatconducting compound
with a rubber spatula to obtain even distribution of compound. If the
area is dirty, wipe the heatsink surface and the busbar clean.
NOTE: Do not clean the surfaces too thoroughly of all grease residue,
since the machined aluminum surface will oxidize in a few seconds
possibly producing a poor heat conductive surface.
C. GTR Installation -
1. Clean the semiconductor contact surfaces with solvent and spread heat
conducting paste on the base of the heat sink.
2. Install the module in the heatsink and secure the clamping screws to the
following torque, tightening the screws alternately 1/8 turn at a time.

Bulletin 1352 5.3 System
3. Check the insulator and connections for damage and clean the insulator
and surrounding area with a solvent dampened paper towel. Tighten the
wires and conductor rails to the connector using the following torques:

D. GTO Installation -
1. Preparation of the semiconductor: Lightly rub the contact surface
carefully against a piece of No. 400 grit emery paper on a flat even
surface with circular movements. Clean the surfaces with a solvent and
immediately apply a very thin layer of heat-conducting compound
(Penitrox A or equivalent) on the contact surfaces using a rubber
spatula. Resolder the firing leads to the GTO thyristor, if required. The
first (grey) lead connects to the gate which is the electrode protruding
from the side of the thyristor through the insulator. The second (red)
lead connects to the other pin which is connected to the thyristor cathode
(The metal rim on the face of the device).
2. Tightening the press clamp: Place the centering pin in position and
check to be sure that length does not prevent the surface of the
semiconductor from fully contacting the heatsink surface. Place the
semiconductor under the press clamp (Type SLZF) and turn the clamp
plus or minus 90° left and right, leaving it in a position where the
connecting leads are not subjected to any stresses or sharp bends. This
procedure ensures spreading of the heat-conducting compound and
adequate surface contact of the semiconductor. Place the Mounting
Force Indicator (dial indicator) on the spring beam and zero it (Fig. 5-1).
Tighten the press clamp to finger tightness (screws tight but no
deflection of the beam). Check that the beam is parallel with the
heatsink surface. Determine the required compression force from the
semiconductor equipment list and read the correct beam deflection from
the charts in Tables 5-7 and 5-8. If not found on the chart, contact your
Allen-Bradley Representative to confirm the correct mounting force for a
particular semiconductor. Continue tightening the clamp using equal
turns on the clamping bolts until the proper force is reached.
3. Tighten wires and conductor busbar to the connector, maintaining the
following torque requirements: | ‘
Metric Thread DIA

4. Clean the insulator of the semiconductor and its surrounding area with a
disposable wiper moistened with solvent if necessary. Check that the
insulators and the connections are intact.
The following example is included to help clarify the procedure for GTO
identification and clamping force determination:
EXAMPLE: A 290 KVA LGU has a bad V17 GTO which was reported by
FLO1. Inspection of the GTO cell showed a manufacturer’s number of
“S6475KR” from Toshiba. By checking the Cross Reference table 5-7, the Allen-
Bradley Part Number for this GTO is listed as 501665.
Page 5-24
Bulletin 1352 5.3 System
Table 5-7 also lists the clamping force required to properly install the GTO.
Note some of the units can be used with different size clamps. This may cause
a requirement for a different deflection measurement as measured by the
force measuring gauge. The clamp number is determined by measuring the
distance between clamping bolts and selecting the proper deflection from
Table 5-8. When tightening the clamp make certain to alternate between
bolts and turn only 1/4 turn at a time.

can be hazardous. Severe injury or death can result from
electrical shock, burn, or unintended actuation of controlled
equipment. Recommended practice is to disconnect and lock out
control equipment from power sources, and allow stored energy
in capacitors to dissipate, if present. If it is necessary to work in
the vicinity of energized equipment, follow the safety related
work practices of NFPA 70E, Electrical Safety Requirements
for Employee Workplaces.
A WARNING: Servicing energized industrial control equipment
Industrial control equipment should be inspected periodically. Inspection
intervals should be based on environmental and operating conditions, and
adjusted as indicated by experience. An initial inspection within 3 to 4
months after installation is suggested. Applicable parts of the following
guidelines should be used:
Contamination - If inspection reveals that dust, dirt, moisture or other
contamination has reached the control equipment, the cause must be
eliminated. This could indicate an incorrect or ineffective enclosure, unsealed
enclosure openings (conduit or other) or incorrect operating procedures.
Dirty, wet or contaminated parts must be replaced unless they can be cleaned
effectively by vacuuming or wiping. DO NOT USE SOLVENTS
Operating Mechanisms - Check for proper functioning and freedom from
sticking or binding. Replace any broken, deformed or badly worn parts or :
assemblies according to individual product renewal parts lists. Check for and
securely re-tighten any loose fasteners. Lubricate only if specified in
individual product instructions.
IMPORTANT: Allen-Bradley magnetic starters, contactors and relays are
designed to operate without lubrication-- do not lubricate these devices since
oil or grease on the pole face (mating surfaces) of the operating magnet may
cause the device to stick in the "ON” mode. Some parts of other devices are
factory lubricated -- if lubrication during use or maintenance of these devices
is needed, it will be specified in their individual instructions. If in doubt,
consult the nearest Allen-Bradley Sales Office for information.
Contacts - Check contacts for both wear and dirt accumulation. Contacts are
not harmed by discoloration and slight pitting. Contacts should never be
filed, as dressing only shortens contact life. Contact spray cleaners should not
be used as their residues on magnet pole faces or in operating mechanisms
may cause sticking, and on contacts can interfere with electrical continuity.
Contacts should only be replaced after silver has become badly worn. Always
replace contacts in complete sets to avoid misalignment and uneven contact
pressure.

6-2.6
6-2.7
6-2.8
6-2.9
6-2.10
Terminals - Loose connections can cause overheating that can lead to
equipment malfunction. Check the tightness of all terminals and bus Бай
connections and securely tighten any loose connections. Replace any parts or
wiring damaged by overheating.
Coils - If a coil exhibits evidence of overheating (cracked, melted or burned
insulation), it must be replaced. In that event, check for and correct
overvoltage or undervoltage conditions, which can cause coil failure. Be sure
to clean any residue of melted coil insulation from other parts of the device or
replace such parts.
Solid State Devices - Solid state devices require little more than a periodic
visual inspection. Printed circuit boards should be inspected to determine
whether all ribbon cables are properly seated in their connectors. Board
locking tabs should also be in place. Necessary replacements should be made
only at the printed circuit (PC) board or plug-in component level. Solvents
should not be used on PC boards. Where blowers are used, air filters if
supplied should be cleaned or changed periodically depending on the specific
environmental conditions encountered. For additional information see
NEMA Standards Publication No. ICS 1.1-1984 entitled: "Safety Guidelines
for the Application, Installation and Maintenance of Solid State Control”
WARNING: Use of other than factory recommended test
equipment for solid state controls may result in damage to the
control or test equipment or unintended actuation of the
controlled equipment.
Bus Connections - The bolts in the DC bus should be checked for tightness
and any dirt or dust on the bus supports should be removed.
Overload Maintenance After a Fault Condition - See NEMA Standards
Publication No. ICS 2.2 entitled: Maintenance of Motor controllers after a
fault condition (also published as NEMA Standards Publication No. ICS 2,
Part ICS 2-302).
Bus Capacitors - The voltage of each section on the monitoring board (3500 -
CBS) should be checked for even division of voltage. If the voltage is
unbalanced, then the capacitors in the CBU should be checked to make
certain they are not shorted. If fuses are provided, they should be checked for
opens. The capacitors should be visually checked for any signs of expansion or
bulging which could cause the capacitor to fail.
“Keep Good Maintenance Records” - This rule will be most helpful in
locating possible intermittent problems by pointing to a particular area of
recurring trouble within the overall system. Further, good maintenance
records will help reduce major costly shutdowns by demanding the use of
proper test equipment and an appropriate inventory of spare parts. For
additional information see NFPA 70B, RECOMMENDED PRACTICE FOR
ELECTRICAL EQUIPMENT MAINTENANCE, published by the National
Fire Protection Association.

NUMBER SYSTEMS

Decimal System - The numbers familiar for a long time are based on the
supposition that the number of available symbols is the same as the number of
fingers on the human hands i.e. 10. This is the concept of decimal number
representation. The available ordered set of digits in the decimal system is:
0123456789
The decimal representation allows us to create unlimited numbers by using
juxtapositional notation. À number magnitude is defined by polynomial
notation in the base 10. Base or radix of the decimal system representation is
10. The number 583 in the decimal system is:
5*102 + 8*10! + 3*100 = 583
If a number has a fractional portion, digits after a decimal point are powers
with negative exponents of the system base 10. E.g. number 437.25 can be
represented in the following polynomial notation:
4*102 + 3*10! + 7*100 + 2*10-1 + 5*10-2 = 437.95
Binary and Hexadecimal Number System - The binary system uses only
digits 0 and 1 for number representation. The base of the binary system is 2
and numerical value are defined by a polynomial of powers of 2. Binary
numbers in written form are notedby a capital letter B at the end of the
number. E.g. binary number 1001B in decimal system is represented as
follows:
1*23 + 0*22 + 0*21 + 1#20 = 9
Every symbol of the binary number is called a bit. The total number of bits in
a binary number is unlimited. In practice binary numbers have 8, 16 or 32
bits (most computers use one of these lengths as a machine word).
Hexadecimal system has a base of 16. Sixteen different symbols are available
for number representation:
0123456789ABCDEF
The capital letters À to F of the English alphabet corresponds to the decimal
numbers 10 to 15. The decimal value is determined as a polynomial of powers
of 16. Hexadecimal numbers in written form are noted by a capital letter H at
the end of thenumber . Hexadecimal number 4A2CH in decimal notation is:
4*163 + 10*162 + 2*161 + 12*160 = 18988.
Conversion from one Number System to Another - Decimal numbers are
normally used in number representation. Microcomputers almost without
exception are based on using hexadecimal numbers. Decimal numbers should
be converted into binary for use in digital electronic circuits. Digital
electronic circuits used in microcomputers can distinguish between onl y two
different stable states which are presented below depending on the
application:
0 or 1
OV or 5V
false or true
reset or set
Page 7-27
Bulletin 1352 System
The natural form of number representation in computer systems is the binary
system. The hexadecimal system has a close connection with the binary
system.
Numbers 12 and 7640 are presented below in the different number systems:
System
Decimal 12 7640
Binary 1100B 1110111011000B
Hexadecimal CH 1DD8H
The most compact way of number representation is the hexadecimal system.
Conversion from binary and hexadecimal systems to the decimal system is
made by adding the powers of the system base as was presented above. A
conversion from the decimal system to one of the other systems is more
cumbersome. In order to convert a number to the desired system it should be.
divided by the base of that system until the quotient is 0. The results of
conversion are partial remainders. E.g. 25 is converted to the binary form as
follows:
Integer Remainder
25 + 2 12 1
12 + 2 6 0
6 + 2 3 0
3 +2 1 1
1 +2 0 1
Result of conversion is 11001B by reading up the list of remainders
Correspondingly conversion from decimal system to hexadecimal is made by
successive division by 16 and writing down partial remainders. The example
of converting number 826 to the hexadecimal form is given below:
Integer Remainder
826 — 16 51 10=A
51 — 16 3 3
3-16 0 3
Result of conversion is 33AH
A conversion from hexadecimal to binary representation is needed more often.
This kind of conversion is easily performed so that each digit of hexadecimal
number can be converted to the binary form and thus a binary juxtapositional
notation 1s made. The opposite conversion is made by breaking up a binary
representation into tetrades (groups of four); convert each tetrade into
hexadecimal form with juxtapositional notation.

Negative Numbers - A negative number in the decimal system is obtained
by placing a minus sign in front of the notation. Computer logic recognizes
only binary representation (zero and one) and does not recognize a minus sign.
A negative number is coded by using the same zero and one representation.
The method of negative number representation is so-called two's complement
representation. A negative number always has 1 in the most significant bit
(the leftmost bit), and a positive number always has a zero in the most
significant bit.
A negative number is obtained by inverting all bits and adding one unit to the
inverted number. E.g. 00000101B (=5) is converted to the negative number
as follows:
00000101B - Binary number to be converted
11111010 - Inverse of each bit
+1 - addition of one
11111011B - the negative equivalent (= —5)

Use of Hexadecimal (binary) Numbers - In most cases, a computer
processes 8 or 16 bit long machine words. Even though 1 or 2 bits are
sufficient for data processing, numbers should be expanded to 8 or 16 bit long
words. The value of the number is not changed when extra zeroes (positive
numbers) or ones (negative numbers) are filled in at the left of the data bit
binary places.
Parameter table locations are 16 bits long. This means that a 16 bit word in
binary representation can be saved in the memory. The largest decimal
number is 32767 and the smallest negative number is — 32768. Examples of
numbers suitable for the Parameter Table presented in the different systems
are given in the table below:
Decimal Hexadecimal Binary
+ 32767 7FFF 0111111111111111
— 32768 8000 1000000000000000
0 0000 0000000000000000
+ 3 0003 0000000000000011
+ 16 0010 0000000000010000
— 3 FFFD 1111111111111101
— 16 FFF0 1111111111110000
When an inverter or LGU shuts down due to a fault, the display panel (CP1 or
CP2) will exhibit the first fault even though subsequent faults occur. It is
advisable to analyze the fault words (210, 211 & 212) for other faults. The
following is an example using Faultwordl 211.
Assume for this example the contents of address 211 in decimal form as 20 or
in hexadecimal as 14H. The number should then be converted to binary form:
Decimal Hexadecimal
Integer Remainder
20+ 2 10 0 14H
10-2 5 0 0001 0100
5+2 2 1 00010100B
2-2 1 0 or in 16 bit notation
1-2 0 1 0000000000010100B
10100B
or in 16 bit notation or in 16 bit notation
0000000000010100B 0000000000010100B
This binary number shows that bits by and b4 are 1. Looking at the parameter
table shows that bits by and b4 indicate the faults were processor fault (22)
and programmable fault (25, motor overload).
