9.20.4.1 Signal diagram (sequence)
The diagram shows how to use restart lock -AS- to ensure a safe stop of the drive and error
free operation of the servo amplifier.
1. Brake the drive in a controlled manner (speed setpoint = 0V
2. When speed = 0 rpm, disable the servo amplifier (Enable = 0V)
3. Activate the restart lock -AS- (AS-Enable = 0V)
Suspended loads can set themselves to motion on motors without brake, because the
motor loses all torque when restart lock -AS- is engaged (AS Enable open and/or 0V).
