1-8 General Information
Section 2
Installation
This section describes the proper mounting and wiring of the
BALDOR Series 10 Inverter. If problems arise, please refer to
the troubleshooting information located in Section 4.
Location and Mounting
Select a mounting surface for the inverter that will allow the
control to be mounted in a vertical position using the four
mounting holes provided. The area selected should allow for
free air circulation around the control. Provide for at least five
inches of clearance on all sides for maximum cooling efficiency.
Caution:
Avoid locating the inverter immediately
above or beside heat generating equipment,
or directly below water or steam pipes.
The ambient temperature around the control should not exceed
40°C. If the control is mounted into an existing control cabinet,
the ambient temperature limits should not be exceeded or failure
of the control may result. In cases where extreme temperatures
are unavoidable, a separate blower fan or cooling system should
be considered. Please contact the factory for derating of
controls operated in temperatures above 40°C.
The standard ventilated NEMA 1 enclosure should not be used
in areas where the control will be subjected to liquids, chemicals,
large amounts of airborne material (i.e. dust or lint), or explosive
atmospheres. Appropriate protection should be provided for the
inverter when used in these environments.
If the control will be subjected to levels of vibration above 0.6G,
then the inverter should be shock mounted. Excessive vibration
within the control could cause internal connections to loosen and
cause component failure or electrical shock hazard.
Installation 2-1
Terminal Access Cover Removal
To remove the Terminal Access Cover insert a small blade
screwdriver into the slots located on the lower left and right hand
corners of the access cover. Use a slight twisting motion while
lifting upward to loosen one side. Use the same motion to
loosen the other side then lift the cover off of the control. To
reinstall, simply snap the cover back into place. See Figure 2-1
below.
Figure 2-1
2-2 Installation
Terminal and Jumper Locations
Figure 2-2 shows the location of the power terminal strip , control
terminal strip , ground lug, and user adjustable jumper locations.
Only motor and input power should be connected to the power
terminal strip. Motor ground and input power earth ground
should be connected to the ground lug. Only external control
wiring should be connected to control terminal strip.

Wiring Considerations
Interconnection wiring is required between the motor control, AC
power source, motor, host control and any operator interface
stations. Use listed closed loop connectors that are of
appropriate size for wire gauge being used. Connectors are to
be installed using crimp tool specified by the manufacturer of the
connector. Only Class 1 wiring should be used.
Installation 2-3
Caution:
Separate over-current protection may be
required by the National Electrical Code. The
installer of this equipment is responsible for
complying with the National Electrical Code
and any applicable local codes which govern
such practices as wiring protection,
grounding, disconnects, and other current
protection.
The inverter is self protected from normal AC line transients and
surges. Additional external protection may be required if high
energy transients are present on the incoming power source.
These transients could be caused by sharing a power source
with arc welding equipment, large motors being started across
the line, or other industrial equipment requiring large surge
currents. To prevent inverter damage due to power source
disturbances the following should be considered:
1.
2.
3.
Connect the inverter on a feeder line separate from those
supplying large inductive loads.
Supply power to the inverter through a suitably sized
isolation transformer. When using an isolation transformer
to power the inverter, always switch the power off and on
between the transformer secondary and the inverter input to
avoid spikes at the inverter when power is removed from

2-6 Installation
AC Power Connections
Connect the fused three phase AC power lines to the input
power terminals L1, L2, and L3. The phase rotation of the input
power is not important since the control is not sensitive to phase
rotation of the input power. For single phase AC power connect
to input power terminals L1 and L2.
Connect an earth ground to the inverter according to any
applicable electrical code. The earth ground should be
connected to the inverter chassis ground screw.
The use of a power disconnect is recommended between the
input power and the inverter to provide a fail safe method to
disconnect the inverter from the input power. The inverter will
remain in a power up condition until all input power is removed
from the control and the internal bus voltage is depleted.
Caution:
Do not attempt to service this equipment
while bus voltage is present within the
inverter. Remove input power and wait at
least 5 minutes for the residual power in the
bus capacitors to dissipate.
Caution:
This unit has an automatic restart feature
that will start the motor whenever input
power is applied and a maintained external
run (FWD or REV) command is present at the
control. If an automatic restart of the motor
could cause personal injury or harm, the
auto restart feature should be defeated with
external control wiring or by adjusting
parameter 82-Start Options.
Installation 2-7
Motor Connections
Connect the three phase power leads of the AC motor to
terminals M1, M2, and M3 of the inverter power terminal strip.
The motor ground lead or case ground should be connected to
the inverter chassis ground screw. The motor should be
connected to the inverter at all times during inverter operation.
If additional motor overload protection is required, the use of
suitably sized motor overload relays are recommended. Motor
overload relays should be connected between the motor and
inverter with the relay trip indicator circuit connected into the
external inverter control circuitry to power down or trip the
inverter in the event of motor overloading.
Caution:
Overload relays with an automatic reset
feature are not recommended in applications
where an automatic restart of the motor
could cause personal injury or harm. If
manual reset relays are not available, then
the automatic reset feature should be
defeated.
If the motor is equipped with a normally closed thermostat, the
thermostat should be connected at terminals MOL and CM of the
control terminal strip. The inverter will also need to be
programmed to trip if this thermostat circuit opens indicating a
motor overload condition. The inverter will need to be
programmed by adjusting parameter 77-External Trip Select and
placing the proper jumper position on jumper terminals J19.
If during initial motor start up the motor rotation is opposite to
that desired, disconnect the input power from the inverter and
wait at least 5 minutes for the bus voltage to bleed off.
Interchange any two of the three motor leads at the inverter
power terminal strip M1, M2, and M3 to change the shaft rotation
of the motor.
2-8 Installation
M-Contactor
If required by local codes or for safety reasons, an M-Contactor
(motor circuit contactor) may be installed. However, incorrect
installation or failure of the M-Contactor or wiring may damage
the control.
Caution:
If an M-Contactor is installed, the control
must be disabled at least 20msec before the
M-Contactor is opened. If the M-Contactor is
opened while the control is supplying
voltage and current to the motor, the control
may me damaged.
A motor circuit contactor provides a positive disconnect of the
motor windings from the control. Opening the M-Contactor
ensures that the control cannot drive the motor. This may be
required during certain manual operations with the load (like
cleaning cutting knives etc.). Figure 2-3 shows how an
M-Contactor is connected to the H series control.

Installation 2-9
Logic Wiring
All logic and control connections are made at the control terminal
strip located on the motor control board. Screw type terminals
are provided for easy connection to your external control station
and meters. The control terminal strip can be divided into four
major categories as follows:
1) Analog command inputs.
2) Analog outputs.
3) Opto Isolated inputs.
4) Relay outputs.
Analog Command Inputs
An external 5kohm potentiometer can be connected at terminals
CM, VIN, and REF. The potentiometer should be connected so
that full resistance is connected from CM and REF. REF is a
5VDC potentiometer reference output. The wiper of the
potentiometer should be connected at terminal VIN. The speed
command input will be recognized at terminals CM and VIN.
When using a potentiometer as the speed command, the Analog
Command Select parameter will need to be programmed to 0 or
1 and jumper J19 will need to be set properly.
An external speed command of 0-5VDC, 0-10VDC, 0-20 mA, or
4- 20mA can be used instead of a potentiometer at terminals CM
and VIN. The positive lead should be connected at terminal VIN
and the negative lead should be connected at terminal CM. The
Analog Command Select parameter should also be programmed
to 0 or 1 and jumper J19 will need to be set properly.
2-10 Installation
Analog Output
One programmable analog output is available for external
monitoring of the drive condition. This output is available at
terminals CM and MET. The output will be 0-10VDC. The
positive lead of the external meter should be connected to
terminal MET and the negative lead should be connected at
terminal CM. The output condition is programmed in parameter
71-Analog Output Select. The analog output gain (max output
voltage) can be adjusted in parameter 70- Analog Output Scale.
Please refer to the Analog Output Table in Section 3 for the
possible monitoring conditions.
Opto Isolated Inputs
Six digital inputs are available at terminals FWD, REV, PS3,
PS2, PS1, and MOL to command various output conditions. The
available command condition at the terminal may change
depending on the operating mode selected. These inputs can be
configured for Pull- Up or Pull-Down Logic. The factory setting is
for Pull-Up Logic. The Inputs will be active when connected to
terminal V+ or when utilizing an external 0-24 VDC power supply
with the power supply common connected to terminal CM. The
selection of Pull-UP or Pull-Down Logic is set by jumper J19.
Depending on the function of the command input, a maintained
switch closure or momentary switch closure will be required.
Connection to a PLC, CNC, or host computer are also possible.
External Trip Connection
Terminal MOL is available for connection to a normally open or
normally closed thermostat in all operating modes. This
connection is available for connection to a motor thermostat or
overload relay. The thermostat or overload relay input can also
be configured for Pull-Up or Pull-Down Logic. If the state of the
motor thermostat or overload relay should ever change indicating
an over-temperature condition, the inverter will automatically
shut down and give an External Trip fault (F07) or will cause the
Installation 2-11
motor to coast to a stop. The fault or coast to stop operation of
the MOL input terminal is selected by parameter 77-External Trip
Select. The selection of pull- up or pull-down logic is set by
jumper J19.
Jumper J19 Input Selection
Jumper J19 is a pin-jumper selector located to the left and below
the control terminal strip (See Figure 2-2). Five jumper positions
are available and are arranged in one group of three positions
and one group of two positions with one shorting jumper in each
group. The group of two located to the right hand side are used
to select the active state of the opto isolated inputs (Pull-Up or
Pull-down Logic). The group of three located to the left hand
side are used to select the type of analog speed command signal
to be used. The available analog speed command signals are
0-5VDC, 0-10VDC, 0-20 mA, and 4-20 mA. A 5kohm 1/2 watt
potentiometer can be used by configuring for 0-5VDC. The
available jumper settings are shown in the following diagram:

Remove input power and wait at least 5
minutes for the residual power in the bus
capacitors to dissipate before changing the
J19 jumper positions.
Relay Outputs
Programmable relay outputs are available for external monitoring
of the drive condition. These outputs are available at terminals
NO (Normally Open) and NC (Normally Closed) with a common
at terminal RCM (Relay Common). The circuit must be
completed by connection at terminals NO or NC and returned to
RCM. The output condition for terminals NO and NC is
programmed in parameter 75- Relay Output Select. The relay
outputs are rated at 115 VAC and 1 Amp maximum.
Selection Of Operation Mode And Connection Diagrams
Several operating modes are available within the Series 10
inverter. These operating modes define the basic operation of
the input terminal configurations and motor control setup. The
operating modes are selected by the setting of jumper J19, and
programming of parameters 21-Operating Mode, 24-Analog
Command Select, 41- Accel/Decel/Coast Select, and 77-External
Trip Select. These functions are briefly shown below. For a

42-Accel Time #1 - Sets the time in seconds for the output
frequency of the inverter to linearly increase from 0 Hz to the
frequency specified by parameter 32-Max Output Frequency.
The adjustable range is from 0 Sec to 600 Sec.
43-Decel Time #1 - Sets the time in seconds for the output
frequency of the inverter to linearly decrease from the frequency
specified by parameter 32-Max Output Frequency to 0 Hz. The
adjustable range is from 0 Sec to 600 Sec.
Operation 3-9
Note: Since the motor uses rotor slip to produce motor torque,
the motor speed will not necessarily increase/decrease
linearly with a linear increase/decrease in applied motor
frequency. Some trial and error may be necessary to find
the optimum Accel and Decel settings for your application.
If the control trips (faults) during rapid accel or decel,
selecting longer ramp times will help eliminate the trips.
52-Torque Boost - The Torque Boost parameter can be
adjusted to provide more or less starting torque from the motor
than is available with the factory setting. The boost adjustment
alters the output voltage of the inverter from the normal value (as
defined by the V/HZ Profile) by increasing or decreasing the
starting output voltage by fixed values.
The boost is set from the factory at a level that is suitable for
most applications. If adjustment is required, adjust the boost up
in small increments until the motor shaft just starts to rotate with
maximum load applied. Caution should be exercised when
adjusting the Torque Boost parameter to prevent motor
overheating at low operating speeds. The Torque Boost is
adjustable from 0% to 25% of the nominal input voltage.
65-Slip Comp Adj - The Slip Compensation Adjustment is
available to compensate for varying load conditions during
normal operation. This parameter will set the maximum amount
of allowable variation in output frequency under varying load
conditions which the control will see as changes in output
current. As the control sees the motor current increase towards
100% of parameter 03-Rated Current (Inverter Rated Current),
the inverter will automatically increase the output frequency to
compensate for slip. The range of adjustment is from 0-12%.
The factory setting is 0%.
3-10 Operation
67-Timed Overload Trip - Sets the amount of overload that will
cause a Timed Overload fault (F20) to occur. A Timed Overload
fault will occur when the output current reaches 150% of the set
value for 1 minute. The Timed Overload Trip is active between
30-100% of the Inverter Rated Current (03-Rated Current)
parameter value. The value of the Timed Overload Trip
parameter should be calculated by the following formula:
Value of Parameter 67 + Motor FLA X 100
03–Rated Current
The range of adjustment is from 0 to 100%. The factory setting
is 0%. The Timed Overload Trip for various output frequencies is

70-Analog Output Scale - Allows scaling of the analog meter
output at control terminal MET to be more or less than the
normal 0-10 VDC level. The factory setting is for 10 VDC output
at full inverter output. The adjustable range is 0-255 in digital
units.
Operation 3-11
71-Analog Output Select - Allows setting of the analog output
available at the control terminal MET to represent various drive
operating conditions. The analog output is 0 to 10 VDC nominal.
The analog output is useful in applications where a higher level
control is monitoring the operation of the control to make process
decisions based on the current status of the inverter. The output
can also be used to drive remote analog meters that may be
located near the operator. Please review the Analog Output

Note: Preset Speed adjustments set the commanded frequency
to be output from the control when the appropriate preset
speed is initiated. Preset speeds can be initiated by
external command at the control terminal strip. Since a
preset speed only sets an operating speed, a motor
direction command will also need to be initiated in order
for the motor to have rotation.
39-Min Freq Torque Limit - Sets the lowest output frequency
the inverter will output when in torque limit. If the motor loading
is large enough to drive the inverter below this output frequency,
the inverter will trip on an overcurrent fault (F16, F17 or F18).
The adjustable range is 0-400 Hz and the factory setting is 10

3-16 Operation
44-Accel Time #2 - Sets the time in seconds for the output
frequency of the inverter to linearly increase from 0 Hz to the
frequency specified by parameter 32-Max Output Frequency.
The adjustable range is from 0.1 Sec to 600 Sec.
45-Decel Time #2 - Sets the time in seconds for the output
frequency of the inverter to linearly decrease from the frequency
specified by parameter 32-Max Output Frequency to 0 Hz. The
adjustable range is from 0.1 Sec to 600 Sec.
Note: Since the motor uses rotor slip to produce motor torque,
the motor speed will not necessarily increase/decrease
linearly with a linear increase/decrease in applied motor
frequency. Some trial and error may be necessary to find
the optimum Accel and Decel settings for your application.
If the control trips (faults) during rapid accel or decel,
selecting longer ramp times will help eliminate the trips.
46-Decel Time Torque Limit - Sets the deceleration rate when
the control is operating in torque limit. Also serves as the
acceleration time when the control is in torque limit due to a
regenerative (overhauling load) condition. The adjustable range
is 0.1-30 seconds.
47-DC Brake Time - Sets the amount of time the DC Injection
Braking will be allowed. There are several available options
including Timed DC Braking, Continuous DC Braking, and Off
(disabled). The options are defined in the following table:

48-DC Brake Voltage - Sets the amount of DC Voltage applied
to the motor windings to cause the motor to stop. Increasing the
DC Brake Voltage setting will cause the motor to have more
braking torque available for stopping. Caution should be
exercised when adjusting this parameter since DC Injection
Braking will cause additional motor heating if used in applications
requiring frequent starts and stops. The adjustable range is from
0-15 % of parameter 52-Torque Boost setting.
3-18 Operation
51-V/HZ Profile - Sets the output V/Hz ratio for all values of
output voltage verses output frequency up to the Control Base
Frequency point. This adjustment will define how much voltage
is applied to the motor in various segments of the output
frequency range. Please note that motor voltage is related to
motor current which can then be related to motor torque. By
adjusting the V/Hz profile you can effectively adjust how much
torque is available from the motor at various speed points. The
available selections include LINEAR (0 or 1) to be used for
constant torque applications such as conveyors, and 50%
Square Law (2 or 3), or 100% Square Law (4 or 5) to be used for
variable torque applications such as centrifugal pumps and
blowers. Even number parameter values will select Auto-Boost
with the maximum amount of Torque Boost set by Parameter
52-Torque Boost. Odd number parameter values will select a
fixed amount of Torque Boost set by Parameter 52-Torque Boost.

53-Control Base Frequency - Sets the point on the V/Hz profile
where the output voltage becomes a constant value with
increasing output frequency. The base frequency point defines
the output frequency where the motor goes from constant torque
(or variable torque) to constant horsepower operation. The
range of adjustment is from 26 to 960 HZ. The factory setting is
60 Hz.
59-Max. Output Volts - Sets the maximum output voltage
available to the motor from the control. The maximum output
voltage of the inverter can be reduced from the line input voltage
to facilitate the use of a motor with an input voltage that is less
than the input voltage to the inverter.
Note: In some cases the Max. Output Volts along with the
Control Base Frequency adjustment can be manipulated
to provide a wider constant torque or wider constant
horsepower speed range than is normally available from
the motor. The Max Output Volts and Control Base
Frequency parameters are normally set to the motors’
rated voltage and rated frequency respectively. Caution
should be exercised if any other values are set into these
parameters. Incorrect values may cause the motor to run
at extreme temperatures or fail prematurely.
61-Load Torque Limit FWD - Sets the maximum amount of
current that is supplied to the motor under a motoring forward
condition before Torque Limiting takes affect. The range of
adjustment is 30- 150% of parameter 03-Rated Current. The
factory setting is 150%.
3-20 Operation
62-Load Torque Limit REV - Sets the maximum amount of
current that is supplied to the motor under a motoring reverse
condition before Torque Limiting takes affect. The range of
adjustment is 30- 150% of parameter 03-Rated Current. The
factory setting is 150%.
63-Regen Torque Limit FWD - Sets the maximum amount of
current that is absorbed by the control from the motor under a
regenerative forward condition before Torque Limiting takes
affect. The range of adjustment is 30-110% of parameter
03-Rated Current. The factory setting is 80%.
64-Regen Torque Limit REV - Sets the maximum amount of
current that is absorbed by the control from the motor under a
regenerative reverse condition before Torque Limiting takes
affect. The range of adjustment is 30-110% of parameter
03-Rated Current. The factory setting is 80%.
68-Number of Restarts - Sets the maximum number of
automatic restart attempts that is allowed before the control will
require a manual restart. After ten minutes without reaching the
maximum number of faults, the number of allowable restarts will
be reset to the value specified in the Number Of Restarts
parameter. This feature is useful in applications that require
unattended operation and automatic operation even in the event
of various fault conditions such as unscheduled power outages.
The control will not automatically clear faults F01 through F10.
The adjustable range is 0 - 8. the factory setting is 0 effectively
disabling the Auto Restart function.
69-Restart Delay - Sets the amount of time allowed between a
fault condition (F11 through F20) and an automatic restart. This
feature is useful in setting a sufficient time period for a fault
condition to be cleared before an automatic restart is attempted.
The adjustable range is 0 to 60 seconds.
Operation 3-21
77-External Trip Select - Sets if the control will trip (Fault F07)
or Coast to Stop if the condition at control terminal MOL is
changed. If set to 0 or 1, then the control will automatically shut
down indicating an External Trip (F07). If set to 2 or 3 the output
to the motor is turned off and the motor is allowed to coast (free
wheel) to a stop. Even values (0 or 2) will cause terminal MOL
to expect a normally low input condition while Odd values (1 or
3) will cause terminal MOL to expect a normally high signal
condition. Jumper J19 sets terminal MOL for Pull-Up or
Pull-Down logic. The following table summarizes the available

Synchro Starts. Also enables or disables the STOP key as an
E-Stop when operating from the control terminal strip and the
Stop function due to a disconnection of an external command
line connected at the control terminal strip. Please review the
following paragraphs and logic table for more information on
available selections.
Auto Restart - In the event of a power failure or inverter fault,
the Series 10 inverter can be adjusted to restart automatically.
The number of restart attempts after a fault condition can be set
by specifying the allowable number of trips within a ten minute
time period. After ten minutes has past since the first trip
occurrence, the trip counter within the microprocessor is reset to
zero. The number of allowable trips can be set by adjusting the
parameter 68-Number of Restarts. The time between a trip and
an auto restart is set by parameter 69-Restart Delay.
Operation 3-23
If the inverter is set in an Auto Restart Mode and normal
operation is using input power to start and stop the motor, the
inverter may be started once every two minutes. The inverter will
prevent operation if more frequent starts are commanded using
line power connection.
Synchro Starts - The Synchro Starts feature is desirable in
applications where the motor shaft is rotating at the time that
power is supplied to the motor from the inverter. If enabled the
control will automatically sense the motor rotational frequency
and immediately output that frequency at start up.
WARNING: A lightly loaded motor may suddenly
accelerate before locking in the proper
speed. Ensure that this operation will not
cause injury to personnel or damage to
driven equipment.

Maintenance
The BALDOR Series 10 inverters require very little maintenance,
if any, and should provide years of trouble free operation when
installed and applied correctly. Occasional visual inspection
should be considered to insure tight wiring connections and to
avoid the build up of any dust, dirt, or foreign debris. The control
should be physically located in such a manner as to protect the
internal circuits and associated external wiring from any
accumulation of moisture or other types of liquid contaminants.
Before attempting to service this equipment, all input power
should be removed from the inverter to avoid the possibility of
electrical shock. The servicing of this equipment should be
handled by a qualified electrical service technician experienced
in the area of high power electronics.
