RUN STOP MODE
RUN RAMP : The motor speed is reduced to zero at a
rate set by RAMP DECEL TIME (
S
4). A 2 second DC
pulse is applied at end of ramp
COAST : The motor is allowed to freewheel to a
standstill
DC INJECTION : On a stop command, the motor
volts are rapidly reduced at constant frequency to
deflux the motor. A low frequency braking current is
then applied until the motor speed is almost zero. This
is followed by a timed DC pulse to hold the motor
shaft.
STOP RAMP : The motor will decelerate at a rate set
by STOP TIME (REFERENCE STOP function block).
