Drive Description
The FlexPak 3000 drive is a full-wave power converter without back rectifier, complete
with a digital current minor loop and a digital major loop for armature voltage or speed
regulation by tachometer or encoder feedback. Figure 1.1 shows the block diagram of
the drive.
The drive employs a wireless construction and uses a keypad (OIM) for drive setup,
including parameter adjustments and measurement unit selection, monitoring, and
diagnostics. Multiple language capability in English, French, German, Spanish, and
Italian is built-in. Reference, feedback, and metering signals can be interfaced to the
drive.
The drive can be controlled:
•
Locally by the Operator Interface Module (OIM).
•
Remotely by using the terminals at the Regulator board terminal strip.
•
Remotely by the CS3000 software or a an optional network kit (AutoMax,
ControlNet, or others).
The reference source (KEYPAD, TERMBLK, NETWORK, or SERIAL) can be selected
through the OIM.

2.1
Run and Jog Sequencing
When powered, the drive is in one of three operating states:
• armature not active (main contactor open)
• run mode
• jog mode
The drive is in run mode if it was started by the RUN input. It remains in run mode until
the completion of a stop sequence.
Important: The drive is in jog mode if it was started by the JOG input. It remains in jog
mode until the completion of a stop sequence or until the RUN input is
asserted. If the RUN input is asserted, the drive switches from jog mode to
run mode. You cannot switch from run mode to jog mode by asserting the
JOG input. You must stop the drive before switching to jog mode.
If you switch from jog mode to run mode, the drive accelerates or decelerates to the
selected run reference as configured by ACCELERATION TIME (P.001) or DECELERATION
TIME (P.002).
2.2
Stop Sequencing
!
ATTENTION: The user must provide an external, hardwired emergency
stop circuit outside of the drive circuitry. This circuit must disable the
system in case of improper operation. Uncontrolled machine operation
can result if this procedure is not followed. Failure to observe this
precaution could result in bodily injury.
The FlexPak 3000 drive can be stopped by:
• Asserting an active stop input
• Opening a permissive input (coast/DB interlock or customer interlock)
• Deasserting the jog input if the drive is in jog mode. Deasserting the jog input will
not initiate the stop sequence until the speed feedback is less than or equal to STOP
SPEED THRESHOLD (P.113) or until the JOG OFF DELAY TIME (P.121) is exceeded,
whichever occurs last.
• Detecting a fault condition
There are three types of stop sequences: Coast/DB, ramp, and current limit. The type
of stop sequence used depends on the source of the stop and your parameter
configuration, as described below.
If a run or jog command is received while the drive is in a ramp or current limit stop
sequence, the stop sequence will be aborted and the drive will continue running or
jogging. Coast/DB stop sequences cannot be aborted.
2-2
FlexPak 3000 DC Drive Software Reference
Coast/DB Stop Sequencing
Coast/DB stop sequencing is used when one of these conditions occurs:
• an active stop input is asserted and STOP MODE SELECT (P.114) is set to COAST/DB
• a permissive input is opened
• a fault condition is detected
In a coast/DB stop sequence:
1. Armature firing angle is forced to a small non-zero value.
2. The drive waits until armature current reaches discontinuous conduction.
3. The main contactor is opened and the DB contactor is closed.
Ramp Stop Sequencing (Run Mode)
Run mode ramp stop sequencing is used when all of these conditions exist:
• an active stop input is asserted
•
STOP MODE SELECT
(P.114) is set to RAMP STOP
• the drive is in run mode
In a ramp stop sequence from run mode:
1. A zero reference is input to the S-curve block.
2. The speed reference ramps toward zero at the rate set by DECELERATION TIME
(P.002) or RAMP STOP DECEL TIME (P.018) (as determined by the setting of STOP
DECEL SELECT (P.122)).
3. The drive waits until speed feedback falls below STOP SPEED THRESHOLD (P.113).
4. A zero reference is input to the current minor loop reference path.
5. The drive waits until armature current reaches discontinuous conduction.
6. The main contactor is opened and the DB contactor is closed.
Ramp Stop Sequencing (Jog Mode)
In jog mode, ramp stop sequencing is used when all of these conditions exist
•
STOP MODE SELECT
(P.114) is set to RAMP STOP
• the drive is in jog mode
• the jog input is deasserted
• Speed feedback is less than or equal to STOP SPEED THRESHOLD (P.113) or JOG OFF
DELAY TIME
(P.121) is exceeded, whichever occurs last
In a ramp stop sequence from jog mode:
1. A zero reference is input to the jog reference ramp block.
2. The jog reference ramps toward zero at the rate set by JOG ACCEL/DECEL TIME
(P.013).
3. The drive waits until speed feedback falls below STOP SPEED THRESHOLD (P.113).
Drive Sequencing
2-3
4. A zero reference is input to the current minor loop reference path.
5. The drive waits until armature current reaches discontinuous conduction.
6. The main contactor is opened and the DB contactor is closed.
Current Limit Stop Sequencing
Current limit stop sequencing is used when one of these conditions occurs:
• an active stop input is asserted, STOP MODE SELECT (P.114) is set to CURRENT LIMIT,
and the drive is in run mode
• the jog input is deasserted when the drive is in jog mode and STOP MODE SELECT
(P.114) is set to CURRENT LIMIT. Deasserting the jog input will not initiate the stop
sequence until the speed feedback is less than or equal to STOP SPEED THRESHOLD
(P.113) or until the JOG OFF DELAY TIME (P.121) is exceeded, whichever occurs last.
In a current limit stop sequence:
1. From run mode: A zero reference is input to the speed loop reference path at the
speed loop summing junction.
From jog mode: A zero reference is input to the jog reference ramp block.
2. Jog mode only: The jog reference ramps toward zero at the rate set by JOG
ACCEL/DECEL TIME (P.013).
3. The drive waits until speed feedback falls below STOP SPEED THRESHOLD (P.113).
If the drive is regenerative (S6R), this phase of the current limit stop sequence
takes little time. If the drive is non-regenerative (S6), the motor coasts during this
phase of the current limit stop sequence.
4. A zero reference is input to the current minor loop reference path.
5. The drive waits until armature current reaches discontinuous conduction.
6. The main contactor is opened and the DB contactor is closed.

CHAPTER 3
Initial Configuration
This chapter describes settings you might need to make when initially starting your
drive, including selecting a control source and changing the settings of the AC line
parameters. Before using the parameters in this chapter, perform Quick Start (see the
OIM manual for detail).
3.1
Selecting a Control Source
The control source determines the source of drive control signals. Control signals
include drive operating signals, such as run and jog, and the drive reference.
You can select the control source on the OIM using the front panel key (
your OIM manual.

The possible control sources are:
•
•
KEYPAD:
Control is through the keypad.
TERMBLK: Control is through Regulator board terminals 16 through 20. See the
hardware manual for terminal descriptions and wiring instructions.
•
NETWORK:
•
SERIAL:
Control is through a network such as the AutoMax Network
Communication kit, DeviceNet Interface kit, or ControlNet Network Communication
kit.
Control is through a personal computer running the CS3000 software.
Important: When switching the control source from NETWORK to any other option,
the internal multiplexor selection parameters that use NETW IN REG 1, 2,
and 3, are not affected. Therefore, any selection that was set to NETW IN
REG# will remain, and the data in NETW IN REG 1, 2, 3 will be the value
used in the control path. (Note that these parameters contain the last
data received from the network before the control source was switched
and will no longer be updated from the network.) To change this, you
must reconfigure any affected selection parameters.

3.2
Configuring the AC Line Parameters
In addition to performing Quick Start, you might need to configure the AC line
parameters for your application. Generally, you only need to configure these
parameters if the default values for these parameters are incorrect for your application.
These parameters should be configured before completing Quick Start. See the OIM
manual for information on Quick Start.

CHAPTER 4
Configuring the Speed Reference
The FlexPak 3000 drive can be configured as a speed regulator or as an armature
voltage regulator, depending on the value of FEEDBACK SELECT (P.200). In this chapter,
the phrase “speed loop” refers to either configuration unless otherwise noted.
The drive can also be configured as either a speed/voltage or current regulator. If the
drive is to be configured as a current regulator, skip this chapter and see Chapter 6.
The speed reference is the speed the speed loop tries to maintain. The drive
processes and scales the speed reference input for use by the speed loop.
The speed loop uses the selected reference value and attempts to keep the speed
feedback from the motor equal to the reference value. If the feedback is less than the
reference, the speed loop increases the motor speed by commanding more current to
the motor. If the reference is less than the feedback, the speed loop decreases the
motor speed by commanding less current to the motor. The speed loop tries to
minimize the amount of error between the speed reference and the speed feedback.
The speed and accuracy with which the speed loop responds to reference or motor
load changes is determined by the speed loop parameters.
Processing the speed reference consists of three major blocks, shown in figure 4.1.

To Figure 5.1,
Speed Loop Block
Diagram
(Figure 4.5)
(Figure 4.2)
(Figure 4.7)
Figure 4.1 – Speed Reference Overview
In the speed reference source select block, the selected reference is scaled and the
amplitude is limited. See section 4.1.
In the speed reference ramp block, the reference value from the speed reference
source select block is modified based on your parameter settings. For example, trim
and rate limiting are applied. See section 4.3.
In the speed reference mode select block, the ramped speed reference signal is
summed with current compounding and outer control loop outputs. See section 4.3.
Configuring the Speed Reference
4-1
4.1
Configuring the Speed Reference Source Block
The speed reference can be either automatic or manual. An automatic (auto)
reference usually comes from a device such as a PLC or a network master. A manual
reference typically comes from a speed potentiometer or the OIM keypad. See the OIM
manual for information on auto and manual references.
!
ATTENTION: When switching from auto to manual or from manual to
auto, the drive will ramp to the reference level provided by the new source
at the rate specified by ACCELERATION TIME (P.001) or DECELERATION TIME
(P.002). Be aware that an abrupt speed change might occur, depending
on the new reference and the rate specified in these parameters. Failure
to observe this precaution could result in bodily injury.
If an I/O Expansion kit is installed, the selected speed reference can be overridden by
a preset speed reference if selected (terminals 59 and 60). See section 4.1.7.
Table 4.1 shows the possible control source and reference source settings. It also
shows the display for the key indicator under
.
Most systems will use one primary reference source. For example, you might use a
network for your reference most of the time, but have the terminal strip reference
available for occasions when the network is not running or for troubleshooting.
The block diagram for the speed reference source is shown in figure 4.2.

4.1.1 Configuring the Keypad (OIM) Speed Reference
must be set to KEYPAD to use the keypad reference. When manual
mode is selected, you enter the speed reference manually through the OIM. See the
OIM manual for information on setting the speed reference through the OIM.
CONTROL SOURCE
The keypad reference cannot be configured to less than MINIMUM SPEED (P.003) or
greater than MAXIMUM SPEED (P.004). The default value of the keypad reference is
MINIMUM SPEED (P.003).
!
ATTENTION: When switching from auto to manual or from manual to
auto, the drive will ramp to the reference level provided by the new source
at the rate specified by ACCELERATION TIME (P.001) or DECELERATION TIME
(P.002). Be aware that an abrupt speed change might occur, depending
on the new reference and the rate specified in these parameters. Failure
to observe this precaution could result in bodily injury.
4.1.2 Configuring the Analog Auto Reference
CONTROL SOURCE must be set to TERMBLK, SERIAL, or KEYPAD to use the analog auto
input as a speed reference. When you use this speed reference, the signal is the
analog auto reference from terminals 19(+) and 20(–) of the Regulator board. Note
that this input can also be used as a current reference to the current minor loop.
You must specify the type of signal that is at terminals 19 and 20 by setting ANLG AUTO
SIGNAL TYPE (P.100) and jumpers J10 and J12 on the Regulator board. The settings of
ANLG AUTO SIGNAL TYPE (P.100) and the jumpers must be the same. See the hardware
manual for information on setting the jumpers.
The drive used the ANLG AUTO GAIN ADJ (P.101), ANLG AUTO SIGNAL TYPE (P.100), and
ANLG AUTO ZERO ADJ (P.102) to scale the analog auto reference signal from terminal 19
and 20 of the Regulator board to produce the ANALOG AUTO REFERENCE (P.188) signal.

4.1.3 Configuring the Analog Manual Reference
must be set to TERMBLK to use the analog manual reference input as
a speed reference. This reference can only be used when the drive is configured as a
speed regulator and MANUAL REF SELECT (P.106) is set to ANALOG.
CONTROL SOURCE
When you use this speed reference, the drive uses the analog manual reference from
terminals 16(+10V), 17(+), and 18(–) of the Regulator board.
The software uses the parameters described in this section to scale the analog
manual reference signal at terminal 16, 17, and 18 to produce the ANALOG MAN

4.1.4 Configuring the Serial Speed Reference
must be set to SERIAL (in the FlexPak 3000 drive or through the
CS3000 software) and AUTO/MANUAL must be set to MANUAL to use the serial speed
reference.
CONTROL SOURCE
If you are using the serial reference from a source such as the CS3000 software, the
reference is input directly from the serial source to the speed reference ramp. The only
parameter related to the serial speed reference is SPD SOURCE SELECT OUT (P.193).
You can use this parameter to check the reference value.
4.1.5 Configuring the Network Speed Reference
CONTROL SOURCE must be set to NETWORK to use the network speed reference. When
the control source is NETWORK, the drive is forced into automatic mode.
The only parameter related to the network speed reference is SPD SOURCE SELECT OUT
(P.193). You can use this parameter to check the reference value.
4.1.6 Configuring the Motor-Operated Potentiometer (MOP) Reference
The MOP function can be used as a manual reference for the speed loop. To use the
MOP function:
• The I/O Expansion kit must be installed.
•
CONTROL SOURCE
•
MANUAL REF SELECT
must be set to TERMBLK.
(P.106) must be set to MOP.
• Switches must be attached to digital inputs 3 and 4 (terminals 63 and 64) of the I/O
Expansion kit. These inputs decrement and increment, respectively, the MOP OUTPUT
(P.191) value.
• The MOP block is shown in figure 4.3.
The MOP output is incremented when digital input 4 (terminal 63) is ON and
decremented when digital input 3 (terminal 62) is ON. MOP OUTPUT is limited between
MAXIMUM SPEED (P.004) and MINIMUM SPEED (P.003). If both digital inputs are ON at the
same time, the MOP output remains at its present value.
(P.115) and MOP DECEL TIME (P.120) set the time in which the MOP
can change from zero to TOP SPEED and vice versa. To prevent the S-curve
block from limiting the rate of change from the MOP OUTPUT, MOP ACCEL TIME has a low
limit equal to ACCELERATION TIME. MOP DECEL TIME has a low limit equal to
DECELERATION TIME.
MOP ACCEL TIME
OUTPUT
To obtain a negative MOP reference, the reverse direction must be selected.
When MOP RESET ENABLE is ON, the MOP output goes to MINIMUM SPEED at the moment
when the drive is stopped following a run or jog. If it is OFF, the MOP OUTPUT remains at
its present level when the drive is stopped. MOP RESET ENABLE also affects the
operation of the keypad reference, even if the I/O Expansion kit is not installed.

Configuring Trim
The trim feature allows an offset to be added to or subtracted from the speed
reference. The amount of trim can be proportional to the upstream speed reference or
incremental. An incremental trim signal is derived from the resultant DRAW
PERCENTAGE OUT (P.196) and the specified TOP SPEED (P.011).
Trim is based on the signal from the source you select in TRIM REFERENCE SELECT
(P.108). The choices are:
•
ANALOG MANUAL: The trim reference signal is based on the analog manual reference
signal (terminals 16, 17, and 18) after it has been limited and scaled.
•
REGISTER :
The trim reference signal is based on the value set in TRIM REF REGISTER
(P.107).
•
ANALOG IN 1 or 2: (I/O Expansion kit only.) The trim reference signal is based on
analog in 1 or 2 from the I/O Expansion kit.
•
NETW IN REG
1, 2, OR 3: (Network only.) The trim reference signal is based on
network input register 1, 2, or 3.
The selected trim reference is limited to within ±TOP SPEED and multiplied with TRIM
(P.109) to generate DRAW PERCENTAGE OUT (P.196). DRAW PERCENTAGE OUT
modifies DECELERATION TIME and ACCELERATION TIME when TRIM REFERENCE SELECT is
set to PROPORTIONAL.
RANGE
The input that can be used for the manual trim reference can also be used as the
analog manual reference. Make sure this input (terminals 16, 17, and 18 on the
Regulator board) is not being used for both functions at the same time.
Example
To use an analog manual reference to generate a 0 to 10% trim adjustment to the
speed reference setting, make these settings:
• Set TRIM REFERENCE SELECT (P.108) to ANALOG MANUAL
• Set TRIM RANGE (P.109) to 10%
• Set TRIM MODE SELECT (P.110) to INCREMENTAL
These settings will provide a 0 to 10% trim adjustment through the entire speed range.

Depending on the polarity of the trim reference, adds to or
subtracts from the speed reference a value that varies based on the speed
reference value. Proportional trim allows multiple drive sections with a common
reference to operate and ramp at different values.
Proportional is a type of draw. By using draw, one section can operate 10% faster
than an upstream section. When a ramp occurs on the common reference, the
two sections will support the 10% draw throughout the ramp. S-CURVE ROUNDING
will interfere with the acceleration and deceleration rates so that the draw will not
be constant. Therefore, it is recommended that S-CURVE ROUNDING be set to 0%
when TRIM MODE SELECT is set to PROPORTIONAL. Incremental trim is not affected
by this limitation.

Speed Reference Ramp
From the speed reference source select block, the value of SPD SOURCE SELECT OUT
(P.193) is amplitude-limited by a minimum/maximum block. This block limits the
reference between MINIMUM SPEED (P.003) and MAXIMUM SPEED (P.004). You can
modify the results from this block using REVERSE DISABLE (P.015) and AUTO MODE MIN
BYPASS (P.111). The inverter block changes the sign of the signal based on the
forward/reverse signal.
If your automatic speed reference signal is already conditioned, you can bypass the
S-curve block by using AUTO MODE RAMP BYPASS (P.112). You can also bypass the
amplitude limit block while in auto mode by using AUTO MODE MIN BYPASS (P.111)
If you use the S-curve block, S-curve smoothing rounds the SPD SOURCE SELECT OUT
(P.193) signal. It provides a smoother transition from constant level speed to the
acceleration or deceleration condition. This helps reduce machine wear.
The S-curve block controls how fast the speed reference changes based on the
ACCELERATION TIME (P.001), DECELERATION TIME (P.002), and S-CURVE ROUNDING
(P.014). Within the S-curve block, S-CURVE ROUNDING specifies the maximum rate of
change allowed for ramping. When a step change occurs on the input, the output’s
rate of change increases by S-CURVE ROUNDING until the acceleration or deceleration
rate is reached. The rate is maintained until the output reaches a distance from the
input where the rate begins decreasing in S-CURVE ROUNDING intervals.
The speed reference ramp block diagram is shown in figure 4.5.

TOP SPEED
depends on several factors:
• If there is no field weakening, the top speed is typically the same as the motor
nameplate base speed.
• If there is field weakening, the top speed is the same as the field-weakened
speed. Top speed is typically more than the base speed when field weakening is
applied.
Whenever TOP SPEED is changed, you should check the positions of jumpers J11
and J14 to make sure they are set as indicated by J11 ANLG TACH VLT SCL (P.792)
and J14 ANLG TACH VLT RNG (P.793). The tachometer wiring might also need to be
changed. See the hardware manual for more information.

ATTENTION: Before starting the drive, this parameter must be set to
base speed or (if the Field Current Regulator kit is installed) the field
weakened speed. The user is responsible for assuring safe conditions
for operating personnel by setting this parameter properly. Failure to
observe this precaution could result in bodily injury.
ATTENTION: Do not allow the motor to exceed the maximum safe speed
of the motor or driven equipment as determined by the equipment
manufacturer. Failure to observe this precaution could result in bodily

4.4.1 Configuring Jog
For information on jog sequencing, see section 2.1, Run and Jog Sequencing.
When you use a jog input (terminals 4 and 1 on the Regulator board or pressing
), the jog signal is conditioned as shown in figure 4.7.
If DIG IN 0 SELECT (P.428) is set to JOG SPEED SELECT, you can use digital input 0
(terminals 12 and 14 on the Regulator board) to choose between two jog speeds, as
set by JOG SPEED 1 (P.012) and JOG SPEED 2 (P.017).
When digital input 0 is:
• Off (0 V): JOG SPEED 1 (P.012) is selected.
• On (+24 V): JOG SPEED 2 (P.017) is selected.
Switching between the two jog speeds while jogging causes the drive to accelerate or
decelerate to the new jog speed at the rate set by JOG ACCEL/DECEL TIME (P.013).
Only JOG SPEED 1 (P.012) is used if DIG IN 0 SELECT is not set to JOG SPEED SELECT.

ATTENTION: This drive can operate at and maintain zero speed when
either of the jog speed parameters (JOG SPEED 1 (P.012) and JOG SPEED 2

5.2.4 Configuring Speed Loop Feedback Lead/Lag Block
Lead/lag adjustments compensate for backlash or coupling issues because of the
feedback device.
To enable this block, set SPD LEADLAG SELECT (P.216) to LEAD/LAG or LAG/LEAD. To
disable this block, set SPD LEADLAG SELECT (P.216) to BYPASS.
When this block is enabled, the selected feedback signal is fed into the lead/lag block.
The SPD LEADLAG LOW FREQ (P.214) and SPD LEADLAG RATIO (P.213) input values are
used to calculate the high break frequency. SPD LEADLAG LOW FREQ (P.214) specifies
the low break frequency and the SPD LEADLAG RATIO (P.213) is the ratio maintained
between the low break and high break frequencies. The low break frequency and ratio
settings are multiplied to determine the high break frequency. For example, if the low
break frequency is 0.50rad/s and the ratio is 10, high break frequency is 5.00rad/s.
The transfer functions for lead/lag and lag/lead are:
Lead/Lag:
Lag/Lead:

Configuring the Speed Loop Current Limits
Armature current is typically limited through two parameters, POSITIVE CURRENT LIM
(P.005) and NEGATIVE CURRENT LIM (P.006). Configure these parameters so they limit
armature current to a range that is consistent with normal operation of the application.
The current limits can also come from:
• Analog inputs 1 and 2 on the I/O Expansion kit.
• Network input registers 1, 2, or 3 from a network.
When POS CURRENT LIM SEL (P.223) or NEG CURRENT LIM SEL (P.224) is set to REGISTER,
the register values are automatically clamped to prevent a minimum (non-zero)
current condition.
Normally, the negative current limit is input as a positive value, then converted to a
negative value by an inverter. If needed, the inverter can be disabled by the NEG CUR
LIM INV EN (P.226) parameter. For example, if the inverter is enabled and the negative
current limit is 150.0% FLA, the actual negative current limit used is –150.0% FLA.
!
ATTENTION: When analog inputs or network registers are used to
control current limits, bipolar values are permitted for the postive and
negative current limits of the current and speed loops. Extreme care
must be exercised when setting the current limit values in this case. If
the negative current limit is set to a non-zero value, the current loop
reference will be clamped to this minimum value, possibly causing
unexpected motor or machine operation, including rapid acceleration or
overspeed. Failure to observe this precaution could result in bodily injury.
If you change NEG CUR LIM INV EN (P.226), POS CURRENT LIM SEL (P.223) and NEG
CURRENT LIM SEL (P.224) are automatically set to REGISTER. When this occurs, an
alarm is generated to notify you of a possible change in the current limits. Make sure
the settings of POS CURRENT LIM SEL (P.223), NEG CURRENT LIM SEL (P.224), POSITIVE
CURRENT LIM (P.005), and NEGATIVE CURRENT LIM (P.006) are correct for your
application before operating the drive.

When CONTROL SOURCE is set to NETWORK, you can reset and assign initial values to
the speed loop PI block. This allows you to switch between current and speed
regulation without stopping the drive.
The PI block is reset when SPD LOOP PI RESET is asserted. The PI block is also held in
reset when the drive is stopped. While reset is asserted, the output of the PI block is
the initial value.
The initial value is determined by SPD LOOP PI INIT SEL and SPD LOOP PI INIT VAL.
If CONTROL SOURCE
LOOP PI INIT SEL set
is not set to NETWORK, the block uses an initial value of zero (SPD
to ZERO.)
When the PI block reset is used, the system must be set to minimize the error between
the actual reference and the commanded reference when changing regulation
schemes to minimize bumps in regulation. For example, when changing from speed to
current regulation, the speed loop PI block’s initial value should be updated with the
actual armature current feedback just before the change is made. The speed
reference should be set to speed feedback before changing from current to speed
regulation.
You can pretorque the speed regulator by setting the speed loop PI block’s initial value
to the desired starting torque value and releasing the block from reset after starting
the drive. The initial torque will be the initial value as the drive begins to ramp to the
reference speed.

These options are only available when using the AutoMax Network Communication
board (CONTROL SOURCE is set to NETWORK and NETW REGISTER MAP SEL (P.914) is set

For diameter-dependent loads, you can scale the feedback to the speed loop. The
feedback is scaled through a multiplier block. The operation of the multiplier block is:
A•B
------------1000
Where:
• A is a speed feedback multiplier (gain)
• B is the speed feedback from the lead/lag block output
When NETW REGISTER MAP SEL (P.914) is set to ALTERNATE, the source for A is the
network register SPEED FEEDBACK GAIN (alternate map, Drop_1, register 38). Even if
the multiplier block is not being used, you must write a value of 1000 to the SPEED
FEEDBACK GAIN register whenever writing to Drop_1. This sets the multiplier block to
unity gain.
If the web is underwound, set UNDERWIND ENABLE (alternate map, Drop_1, register 32,

ATTENTION: When CONTROL SOURCE is changed from NETWORK to
another value, UNDERWIND ENABLE is forced to DISABLED. This could cause
the motor to rotate in the opposite direction than it did under network
control. The active speed reference should be set to zero before starting
the drive from the new control source. Slowly increase the speed
reference until the proper rotation direction can be determined. If it is

CHAPTER 6
Configuring the Current Minor Loop
In all FlexPak 3000 drive configurations, the central control loop is the current minor
loop (CML). This is the control loop that regulates the amount of current flowing
through the motor armature.
The CML is a simple control loop composed of a reference path, a feedback path, and
a forward path that includes a proportional and integral (PI) block. See figure 6.2. The
input to the PI block, known as the error, is the difference between the reference and
feedback. The output of the PI block determines the level of current flowing through the
motor armature. When a reference change occurs, the error becomes non-zero,
causing the PI block output to change. This results in a higher or lower level of current
flowing through the armature until the feedback again becomes equal to the reference.
Figure 6.1 shows the details of the CML reference path. Figure 6.2 shows the details of
the CML regulator block diagram.

When INTERNAL is selected, the inertia compensation signal is generated by scaling
the rate output from the speed/voltage loop S-curve block based on the combined
inertia of the motor and its connected load.
Inertia compensation circuit supports constant diameter, constant field current
applications. The compensation signal is summed with the speed/voltage loop PI
block output to form the reference to the CML.
When INTERNAL is selected, rate output from the speed/voltage loop S-curve block
is scaled based on the combined inertia of the motor and its connected load, as set
through the NORMALIZED INERTIA (P.222).
A network kit must be installed to select the network input registers (NETW IN REG 1,

Selecting and Conditioning CML Reference Selection
A hardware jumper, J15, configures the drive as a current/torque or speed/voltage
regulator. When J15 is set to CURRENT, the input signal TORQUE REFERENCE (P.189) is
the CML reference. TORQUE REFERENCE can come from an analog input, frequency
input, or a network master. When J15 is set to SPEED, the signal SPD LOOP OUTPUT
(P.299) is the CML reference. The software reads the setting of hardware jumper J15
only at powerup. See the hardware manual for information on setting jumpers.
The selected CML reference passes through an amplitude limit block and a rate limit
block. See figure 6.1 for the block diagram.
The amplitude limit block prevents the reference signal from becoming greater than or
less than the limits selected by CML REF LIMIT SELECT (P.311). These limits can be
either the values set by parameters NEGATIVE CURRENT LIM (P.006) and POSITIVE
CURRENT LIM (P.005), or the limit values being used by the speed loop PI block.
The rate limit block limits the rate of change of the selected CML reference based on
value you input for CML REF RATE LIMIT (P.303). CML REF RATE LIMIT (P.303) defines the
minimum allowable time (in milliseconds) that the reference can change from zero to
MAXIMUM CURRENT (P.007). When the drive is stopped, the output of the rate limit block
is clamped to zero. The amplitude and rate-limited CML reference appears as the
output parameter CML REFERENCE (P.396).

The inverters are located on the speed loop feedback path (figure 5.1) and the CML

If CONTROL SOURCE is changed from NETWORK to any other control source, the
UNDERWIND ENABLE bit is set to the default of DISABLED. If the setting was ENABLED,
the motor can rotate in the opposite direction when the drive is restarted with a
control source other than the network.
!
Configuring the Current Minor Loop
ATTENTION: When CONTROL SOURCE is changed from NETWORK to
another value, UNDERWIND ENABLE is forced to DISABLED. This could cause
the motor to rotate in the opposite direction than it did under network
control. The active speed reference should be set to zero before starting
the drive from the new control source. Slowly increase the speed
reference until the proper rotation direction can be determined. If it is
incorrect, change the setting of the FORWARD/REVERSE input. The active
speed reference is based on the new control source and the auto or
manual setting. Failure to observe this precaution could result in severe
bodily injury or loss of life.

6.3
Configuring the Armature Current Feedback
Current transformers and a rectifier bridge are used to determine the armature current
feedback signal that is scaled by a burden resistor (hardware scaling). Ideally, the
selected burden resistor would scale the feedback signal so that 3 volts corresponds
to MAXIMUM CURRENT (P.007). However, since burden resistor selection is limited to
one of four values, it is likely that none of the available burden resistors will result in
ideal scaling. Therefore, software scaling is used to adjust the output of the A/D
converter to the appropriate level. The FlexPak 3000 drive automatically calculates
and sets the software scale factor based on CT TURNS RATIO (P.010), MOTOR RATED
ARM AMPS (P.008), and MAXIMUM CURRENT (P.007). After these parameters have been
set appropriately, hardware jumper J18 must be set according to parameter J18 ARM I
FB RESISTOR (P.395).
An additional gain block in the feedback path allows you to adjust the current feedback
signal by a maximum of ±10% (gain range of 0.900 to 1.100). The CML FEEDBACK GAIN
ADJ (P.300) is typically set for unity gain.
The FlexPak 3000 drive limits the combination of the two gains (software and user
scale factors) to a range of 0.800 and 2.000. For example, suppose the FlexPak 3000
drive sets the software scale factor to 1.950. CML FEEDBACK GAIN ADJ (P.300) is limited
to a maximum value of 1.025 (2.000/1.950) to prevent the combined gain from
exceeding 2.000.
The scaled CML feedback value appears as CML FEEDBACK (P.397).

CHAPTER 8
Configuring the Field Supply
The FlexPak 3000 drive can be used with one of three types of field supplies:
• Standard Field Supply: Provides field control for the standard drive. All configuration
for the standard field supply is through hardware. There are no parameters related
to the standard field supply. This supply generates a fixed field voltage and does not
provide field economy.
• Optional Enhanced Field Supply: Provides electronic field trim, field economy, and
higher voltage field supplies than the standard field supply. The Enhanced Field
Supply kit must be installed to use this field supply.
• Field Current Regulated Supply: Replaces the standard or enhanced field excitation
supply with a current regulated supply. It provides user-adjustable field economy,
constant horsepower operation, and user-adjustable field loss. The Field Current
Regulator kit must be installed to use this field supply.
The Field Current Regulator kit is standard for drives that are 150 to 600HP @
460VAC or 75 to 300HP at 230VAC. It is optional for lower HP drives.
The parameters you will configure for the field supply depend on the supply that is
installed in your drive. You can check FLD CURRENT REGULATOR (P.586) to determine if
the Field Current Regulator kit is installed. If FLD CURRENT REGULATOR (P.586) reports
NOT INSTALLED, you have either the standard field supply, an Enhanced Field Supply
kit, or an incorrectly installed or failed Field Current Regulator kit. Check your drive
and installation notes to verify the type of field supply.
FLD CURRENT REGULATOR
Indicates whether or
not the Field Current
Regulator kit is
installed. If it is
installed, lists the
rating of the kit that is

Configuring Field Economy
Field economy is available if the Enhanced Field Supply kit or Field Current Regulator
kit is installed. It is not available if you are using the standard field supply.
Field economy reduces the field voltage when the motor is at rest, reducing standby
power consumption and prolongs the insulation life of the motor field windings.
When the Field Current Regulator kit is installed, the drive enters field economy when
the drive is first powered up. When the armature becomes active, the drive goes to full
field. After the drive stops, field economy becomes active after the time specified by
FIELD ECONOMY DELAY (P.501). The field economy level is adjustable through FIELD
ECONOMY REF (P.511).
When the Enhanced Field Supply kit is installed, the drive powers up at full field. Field
economy is fixed at 45% of AC line voltage. After the drive stops, field economy
becomes active after the time specified by FIELD ECONOMY DELAY (P.501).
FIELD ECONOMY ACTIVE
(P.599) indicates when field economy is active.
The field current reference for the field loop changes depending on whether or not
field economy is active. If field economy is:
• Inactive: FIELD REF REGISTER (P.513) is limited and is the field current reference.
• Active: MOTOR HOT FLD AMPS (P.510) and FIELD ECONOMY REF (P.511) are multiplied
and used as the field current reference.

8.3.1 Configuring Automatic Field Weakening
The Field Current Regulator kit can provide automatic field weakening. Field
weakening can only be used with speed-regulated drives.
Important: Automatic field weakening cannot be used if FEEDBACK SELECT is set to
ARMATURE VOLT.
When ARMATURE VOLTAGE (P.289) exceeds FLD WEAKEN THRESHOLD (P.518), the field
begins to weaken and the field control loop begins regulating armature voltage. When
field auto weakening is enabled, the drive uses the values of ARMATURE VOLTAGE
(P.289) and FLD WEAKEN THRESHOLD (P.518) to try to maintain a zero input to the first PI
block. If armature voltage increases, a negative value is input to the PI block, which
decreases the high limit to the next PI block. This reduces field current, subsequently
lowering the armature voltage, bringing the input to the first PI block closer to zero.
If IR compensation is used, the threshold where the field control loop begins regulating
armature voltage is FLD WEAKEN THRESHOLD (P.518) less IR COMPENSATION (P.206) at
rated armature current.
To use automatic field weakening, set FIELD AUTO WEAKEN (P.517) to ENABLE.
To turn off automatic field weakening, set FIELD AUTO WEAKEN (P.517) to DISABLE. If
automatic field weakening is disabled, the field current PI block high limit is fixed at 180
degrees.
If needed, you can use FLD WEAKEN LEAD FREQ (P.520) and FLD WEAKEN PROP GAIN
(P.519) to modify the lead frequency and gain of the field auto weaken PI block.

CHAPTER 9
Configuring the Outer Control Loop
The outer control loop (OCL) is typically used to provide dancer position or tension
control in a web processing system. The OCL trims the speed/voltage loop reference
signal. The block diagram for the OCL is shown in figure 9.1.
The OCL can be configured as a:
• Type 1 position regulator, which uses proportional-only control in the forward path.
• Type 2 position regulator, which uses proportional-plus-integral control to reduce
steady state error to zero.
• Type 3 position regulator, which inputs the OCL output directly into the current minor
loop.
• Other OCL schemes.
To configure the OCL as a type 1 position regulator, set the lead break frequency (OCL
PI LEAD FREQ (P.809)) equal to zero (this sets the PI block to proportional only).
To configure the OCL as a type 2 position regulator, set the lead break frequency (OCL
(P.809)) to a non-zero value.
PI LEAD FREQ
When enabled, the OCL executes every 20 msec.
Important: Scaling units of some OCL parameters are not predefined and must be set
by you. See the OIM manual to create OCL user-defined units.

!
ATTENTION: An abrupt speed change could occur when the outer
control loop is enabled. Make sure proper safeguards are in place before
enabling the outer control loop. Failure to observe this precaution can
result in severe bodily injury or loss of life.
To enable the OCL, either the I/O Expansion kit must be installed, CONTROL SOURCE
must be set to NETWORK, or DIG IN 0 SELECT (P.428) must set to OCL ENABLE.
The OCL enable signal (OCL ENABLE (P.849)) must be ON to execute the OCL. If it is OFF
or if the drive is not running, all OCL functions (S-curve, PI, and lead/lag) are held in
reset and OCL OUTPUT (P.848) is zero.

Outer Control Loop Signal Processing
The OCL reference signal passes through a reference and a forward path.
9.2.1 Configuring the OCL Reference Path
You can configure the OCL to include an S-curve block. This prevents the
speed/voltage loop from being “jerked” when the OCL is enabled. The S-curve block
output ramps smoothly from the OCL FEEDBACK (P.847) value to the OCL reference
setpoint to reduce mechanical wear.
The OCL reference signal is fed into the S-curve block, where it is modified by OCL REF
RAMP TIME (P.802) and OCL REF ROUNDING (P.803). These parameters determine the
amount of rounding and minimum amount of time of the OCL reference ramp when the
OCL S-curve block output changes from 0 to full scale and vice versa. Rounding is
performed at the beginning and end of an OCL reference change.
You can check the output of the block through OCL RAMP OUTPUT (P.846).

The difference between the OCL RAMP OUTPUT (P.846) and OCL feedback signal (after

into a PI block. In the PI block, gain (OCL PI PROP GAIN (P.808)) and lead frequency (OCL
PI LEAD FREQ (P.809)) are applied. The output of the PI block is clamped within the
values of OCL PI POSITIVE LIMIT (P.810) and OCL PI NEGATIVE LIMIT (P.811).
The signal from the PI block is fed into the OCL trim range block. Trim determines the
amount of control the OCL signal has on the speed/voltage loop reference. The amount
of trim is set through OCL TRIM RANGE (P.812).

FlexPak 3000 DC Drive Software Reference
If OCL PROP TRIM SELECT (P.813) is enabled, the signal from the trim range block is

Configuring the Outer Control Loop Feedback Path
The OCL lead and lag options allow you to limit ratio errors when the primary ratio
variable changes quickly. Lead/lag adjustments compensate for backlash or coupling
issues with the feedback device.
!
ATTENTION: Lead/lag parameters must be adjusted by a qualified
control engineer. Failure to observe this precaution can result in severe
bodily injury or loss of life.
To enable lead/lag or lag/lead, set OCL LEADLAG SELECT to LEAD/LAG or LAG/LEAD,
respectively. To disable lead/lag or lag/lead, set OCL LEADLAG SELECT to BYPASS.
When lead/lag or lag/lead is selected, the OCL accepts a feedback signal from the
source selected by OCL FEEDBACK SELECT (P.804). You can check the value of this
signal through OCL FEEDBACK (P.847).
OCL FEEDBACK is fed into the lead/lag block. In this block, the OCL LEADLAG LOW FREQ
(P.806) and OCL LEADLAG RATIO (P.807) values are applied to the signal and the drive
calculates the high break frequency. OCL LEADLAG LOW FREQ sets where the signal will
break. The OCL LEADLAG RATIO is the ratio maintained between the low break and high
break frequency. The low frequency and ratio settings are multiplied to determine the
high break frequency. For example, if the low break frequency is 0.50 rad/s and the
ratio is 10, the high break frequency is 5.00 rad/s.
The transfer functions for lead/lag and lag/lead are:
Lead/Lag:

Configuring a Network
You can have a DeviceNet Interface board, AutoMax Network Communication board,
or ControlNet Network Communication board installed in the drive. This chapter
describes the parameters that you can configure for these networks. For information
on the networks, see the appropriate network manual.
Some parameters are only accessible over the network using the alternate register
map (NETW REGISTER MAP SEL (P.914) set to ALTERNATE).
Refer to the appropriate option board instruction manual for more information.

FAULT:
•
USE LAST REF:
The drive continues to run if network communication is lost, using
the last reference value received over the network. The alarm A00004, NETWORK
COMMUNICATION TIMEOUT, is generated if network communication is lost.
•
USE TRMBLK REF: The drive continues to run if network communication is lost,
using the selected auto reference value from the Regulator board terminal strip
(terminals 19 and 20). The drive automatically switches back to the network
reference when network communication is re-established. The alarm A00004,
NETWORK COMMUNICATION TIMEOUT, is generated if network communication is lost.
A fault is generated when network communication is lost, causing the drive
to coast/DB stop.
• 4 (USE TRMBLK CNTL): The drive continues to run if network communication is lost.
The Regulator board terminal strip will become the source for all control (Run,
Jog, Stop, Fault Reset, Direction, and OCL Enable) and speed (auto) reference
signals. The Speed Loop PI Reset and Underwind/Overwind bits cannot be
changed while operating in this mode. They will remain at the last values received
from the network. The drive automatically switches back to the network reference
and control when network communication is re-established. Alarm A00004,
NETWORK COMMUNICATION TIMEOUT, is generated if network communication is lost.
This selection is available only when the ControlNet Network Communication
board is installed in the drive.
!
ATTENTION: When USE TRMBLK REF or USE TRMBLK CNTL are selected,
motor speed and direction changes can occur when network
communication is lost and restored. All terminal block reference and
control signals must be set to correct values for your application. Failure
to observe this precaution could result in damage to, or destruction of,
equipment.
Alarms do not cause the drive to stop. Therefore, some form of hardwired stop must
be available in case of network communication loss, since stopping the drive
through the network might not be possible. Once the drive is stopped, it cannot be
restarted until network communication is re-established or CONTROL SOURCE is
changed to something other than NETWORK.
If CONTROL SOURCE is not set to NETWORK, the loss of network communication does
not affect operation of the drive.
Important: The stop button on the OIM is aways functional, regardless of the vlaue
of this parameter.

output 2. See CML REF LIMIT SELECT (P.311), for information.
The drive-is-ready signal drives digital output 2. This signal
indicates that the drive will start when the next run or jog command is received.
NETW IN REG 1, 2, or 3: Bit 0 of NETW IN REG 1 (P.905), 2 (P.906), or 3 (P.907) drives

11.2 Configuring the Analog Inputs
Important: Analog input 2 (terminals 52 and 53 on the I/O Expansion kit) only
accepts a ±10VDC input signal.
* Default Selection
Figure 11.2 – Analog Inputs Block Diagram
If you use the analog input 1 input, you need to set hardware jumpers and a parameter
that tells the drive what type of signal to expect at the input. For both analog inputs,
you can also set the gain and zero.
Analog inputs are read every 5msec when FEEDBACK SELECT (P.200) is set to DC TACH,
PULSE TACH, or AC TACH. They are read every 10msec when FEEDBACK SELECT (P.200)
is set to ARMATURE VOLT.
To check the scaled signal, use parameters ANLG IN 1 (P.492) or ANLG IN 2 (P.493).

For example, if ANLG IN 1 SIG TYPE is set to 0-10 V, a 0-8 VDC signal produces 80%
of the drive’s full scale value. To produce the drive’s full scale value using the
0-8VDC signal, change ANLG IN 1 GAIN ADJ to 1.250 (8.0V x 1.25 = 10.0V). Gain
values less than 1.000 decrease the resolution of the analog input.
Adjust the zero point (ANLG IN 1 ZERO ADJ (P.414)) before setting gain.

11.3 Configuring the Analog Outputs
The I/O Expansion kit has two unfiltered analog outputs. One can generate a bipolar
DC voltage only. The other can be configured to generate a DC voltage from a 0 to
±10 VDC, 4-20 mA, or 10-50 mA signal. These outputs can be scaled to generate DC
voltage signals as low as 5 V, but maximum resolution (0.025%) is obtained when the
full scale output signal is used. The full scale value (FSV) is determined based on the
selected parameter group; load, speed, voltage, power, field or other.
Analog outputs are read every 5msec when FEEDBACK SELECT (P.200) is set to DC
TACH, PULSE TACH, or AC TACH. They are read every 10msec when FEEDBACK SELECT
(P.200) is set to ARMATURE VOLT.

Configuring the Drive to Use
Level Detectors
The level detectors detect when the absolute value of a signal becomes greater than
or equal to a specified threshold for longer than a specified period. They can be used
as zero-speed detectors, at-speed detectors, or limit switches. They are also used to
drive optional I/O Expansion kit digital output 1 or 2.
To use the level detectors, DIG OUT 1 SELECT (P.409) or DIG OUT 2 SELECT (P.411) must
be set to LEVEL DETECT 1 OUTPUT or LEVEL DETECT 2 OUTPUT. Level detector outputs
can also be monitored over the AutoMax network.

13.2 Adjusting the Tachometer or Encoder
Loss Sensitivity
Normally, tachometer or encoder loss is reported when the SCR firing angle reaches
109° when armature current is present and the speed feedback is less than 5% of TOP
SPEED (P.011). If you are getting nuisance trips associated with high inertia loads, you
can adjust the SCR angle at which tachometer or encoder loss is reported.
!
ATTENTION: This equipment is at line voltage when AC power is
connected to the drive. Disconnect and lock out incoming power to the
drive before proceeding. After power is removed, verify that no voltage
exists at power terminals 181, 182, and 183 before touching any internal
parts of the drive. Failure to observe this precaution could result in severe
bodily injury or loss of life.
If you are getting nuisance tachometer or encoder loss trips:
Step 1.
Lockout and tag power as necessary.
Step 2.
Turn off power to the drive.
Step 3.
Check all tachometer or encoder lead connections, including polarity.
Step 4.
If there is no problem with the connections, increase TACH LOSS SCR ANGLE
by 1 degree.
Step 5.
Restart the drive.

If a tachometer or encoder loss is reported and the angle is less than 127°,
repeat this procedure.

13.4 SCR Diagnostics and Adjusting Open
SCR Sensitivity
Under normal drive operation, the load carried by each SCR is relatively equal, as
shown in figure 13.1.
Figure 13.1 – SCR Armature Current During Normal Operation
If one or more SCRs fail to turn to on, a unique pattern of insufficient or missing current
pulses results, as shown in figure 13.2.
Open SCR diagnostics detects SCRs that are not conducting by analyzing the level of
current produced by each SCR pair firing. If one or more SCR consistently fails to
produce current at a level approximately equal to other SCRs that fired, the drive
concludes that an open SCR has occurred.
The open SCR diagnostic calculates the percentage deviation of current feedback for
each pair of SCRs from the average current feedback. The percent deviation must
exceed the value set for OPEN SCR SENSITIVITY (P.600) before the diagnostic proceeds
to the next part of the diagnostic.
In the next part of the diagnostic, deviations from the average current are integrated
over time to eliminate transient effects from the calculation. When the integration
reaches the value of OPEN SCR TRIP THRESH (P.601), an open SCR fault is generated.
If you are experiencing nuisance SCR faults, you can use these parameters to increase
the tolerance to conditions that could trigger an open SCR fault.

severe bodily injury or loss of life.
ATTENTION: This is an open loop test. Lock the motor shaft or
disconnect the motor armature leads from the drive and replace them
with a dummy load. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION: If the field is disconnected, the armature must be locked
to prevent rotation. Failure to observe this precaution could result in bodily
injury.
ATTENTION: This equipment is at line voltage when AC power is
connected to the drive. Disconnect and lock out incoming power to the
drive before proceeding. After power is removed, verify that no voltage

An armature phase fire test mode is available to verify the operation of the S6 or S6R
rectifier bridge. This test should only be performed by qualified personnel. Note that
this test is not available through the DCM.
To perform an armature phase fire test:
Step 1.
Lockout and tag power as necessary.
Step 2.
Turn off power to the drive.
Step 3.
Either lock the motor armature to prevent rotation or disconnect the motor
armature leads from the drive and replace with a dummy load.
When locking the motor armature, the motor field winding can be
disconnected to prevent excessive torque. If the motor field winding is
disconnected, jumper J20 should be set to DISABLE to inhibit field current
loss faults.

Step 10. Set PHASE FIRE TEST DELTA (P.309) to 55 degrees. Slowly increase PHASE
FIRE TEST DELTA until a steady pattern of “bumps” appears on the
oscilloscope. If all thyristors in the selected bridge are operating, there will
be six bumps per AC line cycle, similar to the example in figure 13.1. If any
bumps are missing, one or more thyristors are not conducting, similar to the
example in figure 13.3.
Note that conduction will not begin until the firing angle is sufficiently
advanced (PHASE FIRE TEST DELTA (P.309) more than 60 degrees). A rate
limit block limits the rate of change of firing angle advances to prevent
sudden increases in current. To prevent the drive from entering continuous
conduction during this test, PHASE FIRE TEST DELTA (P.309) should not
exceed 89 degrees.

13.6 Setting Reversed Tachometer or Reversed Encoder
Lead Detection
The FlexPak 3000 drive includes an algorithm for detecting reversed speed feedback
wiring. The logic verifies that the difference between the speed reference and the
speed feedback is greater than the threshold set by TACH LEAD FLT THRESH (P.227) for
the amount of time set by TACH LEAD FLT DELAY (P.228). When the threshold is greater
than the difference for the specified delay, and the speed reference and speed
feedback are opposite in polarity, a REVERSED TACH LEADS fault is generated
(fault F00014).
Fault F00014 can also be caused by an overhauling load, improper drive tuning, or a
tachometer or encoder loss.
The tachometer lead fault parameters have default values that are set so that reversed
tachometer lead detection is effectively disabled. You must empirically determine
values for these parameters so that reversed tachometer or encoder wiring can be
detected without generating nuisance faults.
The ability to check for reversed tachometer lead faults is useful for machine
manufacturers that require their equipment to be disassembled for shipping and
reassembled and rewired at a customer site.
This option is not available for AC tachometers.

13.7 Setting Up Inverting Fault Avoidance
An inverting fault is an uncontrollable high current resulting from commutation failure.
It is typically caused by an excessive armature-to-line voltage ratio, which can be
caused by situations such as a line voltage dip, a poorly tuned field regulator, or an
overhauling load. Inverting faults can also be caused by thyristor misfiring induced by
noise, or a current minor loop rate limit that is set too fast.
Inverting faults can cause:
•
•
•
•
•
clearing of the AC line fuses that protect the armature thyristors
tripping of an inverting fault circuit breaker
clearing of an armature DC fuse
loss of thyristors
degradation of commutator due to high current
• flashover in the motor or power unit
Inverting faults are only a concern in regenerative DC drive applications. Typically, a
regenerative drive application uses a regenerative power unit (S6R). Non-regenerative
power units (S6) can also be used in a regenerative configuration, such as an unwinder
using continuous regeneration or if the drive uses field reversing for stopping.
Inverting fault avoidance can be used in regenerative drive applications to prevent the
occurrence of an inverting fault. If inverting fault avoidance is used, the drive
recognizes conditions that could lead to an inverting fault and dynamically adjusts
drive operation to prevent an inverting fault.

ATTENTION: When activated, inverting fault avoidance takes control of
the current minor loop by either forcing the current reference to zero (if
the drive is regenerating) or by disabling the regenerative bridge (if the
drive is not regenerating). The user must analyze the application to
determine whether or not inverting fault avoidance should be used.
Failure to observe this precaution could result in bodily injury.
ATTENTION: Enabling the inverting fault avoidance logic does not
guarantee that an inverting fault will not occur in all instances. The user
must provide safeguards against inverting faults. Failure to observe this
precaution could result in bodily injury.

A request to regenerate occurs when the current minor loop
reference and feedback become opposite polarity. When a request
to regenerate is detected, the drive immediately stops (coast/DB)
and generates an INVERTING FAULT AVOIDED fault (F00015).
DELAY BEFORE FAULT
Yes
• Immediately forces the current minor loop reference to zero.
• Logs an INVERTING FAULT AVOIDED alarm (A00005).
• Continues operate normally for up to two seconds. The drive can
generate a motoring current as needed but will coast while a
demand for regenerative current exists.
• If the demand for regenerative current persists for approximately
two seconds, the drive:
• Stops (coast/DB).
• Generates an INVERTING FAULT AVOIDED fault (F00015).
• If the conditions that caused the alarm return to normal before
two seconds, the drive returns to normal operation (the
regenerative bridge is re-enabled) without stopping.
No (drive is
motoring)
• Logs an INVERTING FAULT AVOIDED alarm.
• Continues normal operation on the motoring bridge until a
request to regenerate is detected.
• When a request to regenerate is detected, the drive continues
operate normally for up to two seconds. The drive can generate a
motoring current as needed but will coast while a demand for
regenerative current exists.
• If the demand for regenerative current persists for approximately
two seconds, the drive:
• Stops (coast/DB).
• Generates an INVERTING FAULT AVOIDED fault (F00015).
• If the conditions that caused the alarm return to normal before
two seconds, the drive returns to normal operation (the
regenerative bridge is re-enabled) without stopping.

APPENDIX B
New Features in Version 4.3
The FlexPak 3000 drive Version 4.3 software adds a configurable scan loop time to
the previous version of the drive. See parameter P.019 in chapter 5.
Features Added to Version 4.2
The FlexPak 3000 drive Version 4.2 software added these features to the previous
version of the drive:
•
Support for ControlNet Network Communication Board
When the ControlNet Network Communication board is installed in the drive,
complete access to all drive functions is available. See the ControlNet Network
Communications Option Board manual, D2-3425, for information on setting up
and using the ControlNet Network Communication board.
•
Type III Position Regulator
The FlexPak 3000 firmware was modified to allow the Outer Control Loop to be
used as the Current Minor Loop reference. This allows the drive to be configured
as a Type III position regulator. To use this feature, the drive must also be
configured as a current regulator via hardware jumper J15. A new parameter, OCL
TYPE3 POSN REG EN (P.814), was added to support this feature.
•
AC Line Phase Loss Detection
The FlexPak 3000 drive can generate a phase loss fault when the AC line drops
below 75% of a value set by the operator. A new parameter, PHASE LOSS
DETECTION (P.609), was added to support this feature.
•
Changes to Contactor Sequencing Timing
The main contactor sequencing was changed to support drive operation with main
contactors whose opening and closing times are longer than normal (such as
those on higher horsepower drives). The drive now waits up to 1000 ms before
generating faults or alarms.
•
New Features in Version 4.3
Other Changes
•
Additional Outer Control Loop feedback signal sources
•
Extended limits for the Outer Control Loop Trim Range parameter
•
New parameters added to the AutoMax Network alternate register map

GLOSSARY
altitude - The atmospheric altitude (height above sea level) at which the motor or
drive will be operating.
armature -The portion of the DC motor that rotates.
armature resistance - Measured in ohms at 25 degrees Celsius (cold).
base speed - T. he speed that a DC motor develops at rated armature voltage and
rated field current with rated load applied. Typically nameplate data.
configurable - Input parameter whose values can only be modified while the drive is
stopped (not running or jogging).
constant speed - Used to describe a motor that changes speed only slightly from a
no-load to a full-load condition.
DC motor - A motor using either generated or rectified DC power. A DC motor is
usually used when variable speed operation is required.
DB - Dynamic Braking.
default value - Parameter values that are stored in the drive’s read-only memory
(ROM).
drive - Power converting equipment supplying electrical power to a motor.
efficiency - The ratio of mechanical output to electrical input. It represents the
effectiveness with which the motor converts electrical energy to mechanical energy.
field - A term commonly used to describe the stationary (stator) member of a
DC motor. The field provides the magnetic field with which the mechanically rotating
(armature or rotor) member interacts.
horsepower - The measure of the rate of work. One horsepower is equivalent to lifting
33,000 pounds to a height of one foot in one minute. The horsepower of a motor is
expressed as a function of torque and RPM. For motors, you can approximate
horsepower using this formula:
RPM
HP = T × ------------5250
where:
Glossary
•
HP = horsepower
•
T = Torque (in lb-ft)
•
RPM = revolutions per minute
Glossary-1
inertial load - A load (such as flywheel or fan) that tends to cause the motor shaft to
continue to rotate after power has been removed (stored kinetic energy). If this
continued rotation cannot be tolerated, some mechanical or electrical braking means
must be applied. This application might require a special motor due to the energy
required to accelerate the inertia. Inertia is measured in either lb-ft2 or oz-in2.
Load RPM 2
Inertia Reflected to the Shaft of the Motor = Load Inertia ×  ------------------------------
 Motor RPM
input parameter - You can change the value of the parameter through the OIM.
LCD - Liquid Crystal Display.
LED - Light Emitting Diode.
motor - A device that converts electrical energy to mechanical energy to turn a shaft.
motor electrical time constant - The ratio of electrical inductance (La) to armature
resistance (Ra).
motor identification •
Frame designation (actual frame size in which the motor is built)
•
Horsepower, speed, design and enclosure
•
Voltage, frequency and number of phases of power supply
•
Class of insulation and time rating
•
Application
motor nameplate - The plate on the outside of a motor that describes the motor, HP,
voltage, RPM, efficiency, design, enclosure, etc.
motor thermostat - Unit applied directly to the motor’s windings that senses winding
temperature and might automatically break the circuit in an overheating situation.
non-retentive - Changes to the parameter value are not saved when power is
removed.
output parameter - Provides output information. Value cannot be changed through
the OIM.
power (P) in kW - The measure of the rate of work. One kilowatt (kW) is equivalent to
lifting 98 kg to a height of one meter in one second. The kW rating of a motor is
expressed as a function of torque and RPM. For motors, you can use this approximate
formula:
RPM
P = T × ------------9550
where:
Glossary-2
•
P = horsepower
•
T= Torque (in Nm)
•
RPM = revolutions per minute
FlexPak 3000 DC Drive Software Reference
rated full load current - Armature current in amperes.
retentive - Parameter value is stored in the drive even when power is off. To save
changes to the values, a Memory Save must be performed before removing power.
RPM - revolutions per minute. The number of times per minute the shaft of the motor
(machine) rotates.
service factor (SF) - hen used on a motor nameplate, a number that indicates how
much above the nameplate rating a motor can be loaded without causing serious
degradation. For example, a 1.15 SF can produce 15% greater torque than a 1.0 SF
rating of the same motor.
tachometer - Normally used as a rotation sensing device. Tachometers are typically
attached to the output shaft of a motor requiring close speed regulation. The
tachometer feeds its signal to a control loop, which adjusts its input to the motor
accordingly.
top speed - The highest speed a drive can achieve. Top speed equals base speed
when there is no field weakening.
torque - Turning force delivered by a motor or gearmotor shaft, usually expressed in
pounds-feet or newton-meters:
5250
lb-ft = HP × ------------- = Full Load Torque
RPM
9550
Nm = P(kW) × ------------- = Full Load Torque
RPM
tunable - Input parameter whose value can be modified at any time (when the drive is
stopped, running, or jogging).
