4.5.2 WITH POWER ON
4.5.2.1 Run the motor up to full speed and command the starter off. If the motor reaches zero
speed from the DC injection cycle, close the switch to the Disable Input to disable the
braking.
4.5.2.2 Re-adjust the braking torque pot, RV2, if the actual braking time has to be increased or
decreased to bring the motor to zero speed.
4.5.2.3 Once the braking torque is set, then adjust RV1 to match the DC injection time with the
actual stopping time of the motor. Typically, the injection should decease when the motor
is at zero speed or shortly after. LD1, DC INJCT is an indication of braking. Each 10%
graduation in RV1 corresponds to approximately 6 seconds.
WARNING!
ALLOW TIME FOR THE MOTOR TO COOL BEFORE ANOTHER
START / STOP SEQUENCE IS INITIATED
FREQUENT START / STOP COULD CAUSE MOTOR DAMAGE
DUE TO OVERHEATING
