Decel to Stop (B3-03 = 00)
Upon removal of the FWD or REV run command, the motor decelerates at a rate determined by the
time set in deceleration time 1 (B5-02) and DC injection braking is applied after the DC injection start
frequency, 0.5 Hz, has been reached. If the deceleration time is set too short or the load inertia is too
large, an overvoltage fault (OV) may occur during deceleration. In this case, increase the
deceleration time or install an optional braking transistor and/or braking resistor.
Braking torque: without braking resistor, approximately 20% of motor rated torque; with braking
option, approximately 120% of motor rated torque.
