CUR. LIM.
Limits DC motor armature current (torque) to prevent damage to the motor or control. The current limit is
set for 125% of the rated motor current. Clockwise rotation of this trimpot increases the armature current
(or torque produced).
1) Turn drive power OFF!
2) Connect a DC Ammeter in series with the +ARM line (bA on motor and +ARM on the control). Preset the
current limit trimpot CCW.
3) Turn power on and set speedpot to 50%.
4) Increase the motor load until the motor stalls (zero RPM).
5) Set CUR. LIM. trimpot by adjusting CW to 125% of the rated motor armature current (see “TRIMPOT CHART”).
ACCEL
Allows adjustment of acceleration by user.
1) Clockwise trimpot rotation increases length of acceleration time needed for the control to reach full speed.
DECEL
Allows adjustment of deceleration by user.
1) Clockwise trimpot rotation increases length of deceleration time needed for the control to reach zero speed.
