Explanation
The motor brakes with the ramp-down time
p1121 of the ramp-function generator. The con‐
verter switches off the motor at standstill.
The converter goes into the "ready" state. If, in
addition, bit 3 = 1, the converter switches on the
motor.
Switch off the motor immediately, the motor
then coasts down to a standstill.
The motor can be switched on (ON command).
Fast stopping
The motor brakes with the OFF3 ramp-down
time p1135 down to standstill.
The motor can be switched on (ON command).
Immediately switch-off motor (cancel pulses).
Switch-on motor (pulses can be enabled).
