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 = 0 V)
2.
When speed = 0 rpm, disable the servo amplifier (Enable = 0 V)
3.
Activate the restart lock -AS- (AS-Enable = 0 V)
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 0 V).
