Operation and Troubleshooting
Acceleration
2 seconds
Deceleration
2 seconds
Torque
200% of rated (based on proper DIP switch settings)
Refer to Figure 4 for the trim potentiometer locations and approximate initial settings. If you
need to readjust the control for your specific applications, proceed as follows:
WARNING
Use a nonmetallic or insulated adjustment tool (such as a television alignment tool) for internal
adjustments. Circuit components are not at ground potential and accidental short circuiting and
shock hazard may occur with conducting tools. Adjustment should be made only by qualified
service personnel.
Minimum and Maximum Speed:
The MIN and MAX trim potentiometers have been factory
calibrated. The lowest MIN trim potentiometer setting (fully counterclockwise) corresponds to 0
RPM and the highest MIN setting (fully clockwise) corresponds to approximately 30% of rated
speed.
The lowest MAX trim potentiometer setting (fully counterclockwise) corresponds to 60% of
rated speed and the highest MAX trim potentiometer setting (fully clockwise) corresponds to
approximately 120% of rated speed. Refer to Figure 4 for trim potentiometer location and
settings. Adjustment of the MIN and MAX trim potentiometers may have to be repeated several
times to arrive at the desired speeds.
NOTE: Increasing the MIN potentiometer
setting will increase the maximum speed
beyond nameplate speed. The MAX trim
potentiometer will need to be readjusted.
Torque (Current) Limiting Adjustment:
The
TORQ trim potentiometer (Figure 4) has been
calibrated to limit current to 200 to 250% of
the motor’s rated current, assuming the DIP
switches are set properly. The motor’s torque
output can be reduced to zero or stall torque.
Turn the TORQ trim potentiometer
counterclockwise to decrease the torque and
clockwise to increase the torque.
Acceleration Adjustment
: Adjusting the
ACCEL trim potentiometer (See Figure 4)
counterclockwise decreases the motor's
acceleration time down to a minimum of approximately 0.2 seconds. A clockwise adjustment
increases the rate up to a maximum of approximately 10 seconds.
Deceleration Adjustment:
Adjusting the DECEL trim potentiometer (See Figure 4)
counterclockwise decreases the motor’s deceleration time down to a minimum of approximately
0.2 seconds. A clockwise adjustment increases the rate up to a maximum of approximately 10
seconds.

decreased torque limit at lower speeds.
