Calibration procedure
REGULATION (IR COMP)
The IR COMP setting determines the degree to which motor
speed is held constant as the motor load changes. It is
factory set for optimum motor regulation.
Calibrate the drive using the following procedure:
1.Set the MIN SPD, IR COMP, ACCEL and DECEL trimpots
to zero (full CCW).
Recalibrate the IR COMP setting when using a lower
horsepower motor. Refer to the recommended IR COMP
settings in Figure 6 (page 8), or recalibrate using the
following procedure:
2.Set the TORQUE trimpot to maximum (full CW).
3.Set the MAX SPD trimpot to midrange (approximate 12
o’clock position).
If the motor does not maintain set speed as the load
changes, gradually rotate the IR COMP trimpot CW. If the
motor oscillates (overcompensation), the IR COMP trimpot
may be set too high. Turn the IR COMP trimpot CCW to
stabilize the motor.
4.Turn the speed adjust potentiometer on front cover to
zero.
5.Apply power to the drive.
6.Calibrate the trimpots as follows:
TORQUE LIMIT (TORQUE)
MINIMUM SPEED (MIN SPD)
WARNING
The MIN SPD setting determines the motor speed when the
speed adjust potentiometer is turned full CCW or reference
signal is at its minimum. It is factory set to zero speed.
Although TORQUE is set to 150% of drive
nameplate current rating, continuous opera­tion
beyond that rating may damage the motor. If you
intend to operate beyond the rating, contact your
Applied Industrial Technologies representative for
assistance.
To calibrate, turn the speed adjust potentiometer full CCW
or reference signal is at its minimum. Adjust the MIN SPD
trimpot until the motor has stopped, or is running at the
desired minimum speed.
The TORQUE setting determines the maximum torque for
accelerating and driving the motor. TORQUE is factory set
at 150% of maximum drive current. You must recalibrate
the TORQUE setting if using a lower current rated motor.
See Figure 6 (page 8) for typical TORQUE and IR COMP
settings.
MAXIMUM SPEED (MAX SPD)
The MAX SPD setting determines the motor speed
when the speed adjust potentiometer is turned full CW
or reference signal is at its maximum. It is factory set for
maximum rated speed.
1.With no power applied to the drive, connect a DC
ammeter in series with the motor armature.
2.Set the TORQUE trimpot to full CCW.
To calibrate, set the MAX SPD trimpot full CCW. Turn the
speed adjust potentiometer full CW or reference signal is at
its maximum. Adjust the MAX SPD trimpot until the desired
maximum motor speed is reached.
3.Carefully lock the motor armature. Ensure that the motor
is firmly mounted.
4.Apply line power. The motor should be stopped.
Note: Check the MIN SPD and MAX SPD adjustments after
recalibrating to verify that the motor runs at the desired
minimum and maximum speed.
5.Set the speed potentiometer or reference signal to
maximum speed. The motor should remain stopped.
6.Slowly rotate the TORQUE trimpot clockwise (CW) until
the ammeter reads 150% of maximum motor armature
current.
7.Set the speed adjust potentiometer or reference signal to
zero speed.
8.Remove power from the drive.
9.Remove the lock from the motor shaft.
10.Remove the ammeter in series with the motor armature.

Calibration (continued)
Operation
ACCELERATION (ACCEL)
WARNING
Change voltage switch settings only when the drive
is disconnected from AC line voltage. Make sure
both switches are set to their correct position. If
the switches are improperly set to a lower voltage
position, the motor will not run at full voltage. If the
switches are improperly set to a higher voltage
position, the motor will overspeed, which may cause
motor damage.
The ACCEL setting determines the time the motor takes
to ramp to a higher speed. See Specifications on page 3
for approximate acceleration times. The ACCEL setting is
factory set to its minimum value (full CCW).
Turn the ACCEL trimpot CW to increase the acceleration
time, and CCW to decrease the acceleration time.
DECELERATION (DECEL)
Before applying power
The DECEL setting determines the time the motor takes
to ramp to a lower speed. See Specifications on page 3
for approximate decelerating times. The DECEL setting is
factory set to its minimum value (full CCW).
Calibration
Turn the DECEL trimpot CW to increase the deceleration
time, and CCW to decrease the deceleration time.
Calibration procedure conclusion
This concludes the calibration procedure. The control
should now be calibrated for optimum operation.

WARNING
WARNING
Do not change the motor direction while the motor
is running. The motor must come to a complete stop
before reversing. Changing motor direction before
allowing the motor to completely stop will cause
excessively high current to flow in the armature
circuit, and may damage the drive and/or motor.
Decelerating to minimum speed, inhibit operation,
or coasting to a stop is recom­mended for frequent
starts and stops. Do not use any of these methods
for emer­gency stopping. They may not stop a drive
that is malfunctioning. Removing the AC line power
(both L1 and L2) is the only acceptable method for
emergency stopping.
1.Set the FORWARD/OFF/REVERSE switch to the OFF

2.Set the speed adjust potentiometer (SPEED dial) to “0”, or
full CCW.
Maintianing a connection between the inhibit pins
(Figure 7) causes the motor to coast to minimum speed.
Removing the connection between the inhibit pins allow the
motor to accelerate to the speed set by the speed adjust
potentiometer.
3.Apply AC line voltage.
4.Set the FORWARD/OFF/REVERSE switch to the desired
direction of rotation.
5.Slowly advance the speed adjust potentiometer CW.
The motor slowly accelerates as the potentiometer is turned CW. Likewise, the motor slowly decelerates as the
potenti­ometer is turned CCW. Continue until the desired
speed is reached.

Twist inhibit wires and separate them from other powercarrying wires or sources of electrical noise. Use shielded
cable if the inhibit wires are longer than 18 inches (46 cm). If
shielded cable is used, ground only one end of the shield to
Earth ground. Do not ground both ends of the shield.
6.To bring the motor to a stop, turn the speed adjust
