3.7.2.4 Quick stop
This command serves to activate Quick stop
when the operation is enabled.
The drive is braked to standstill irrespective of the defined setpoint within the
deceleration time set for Quick stop
.
It is changed to the device state "Quick stop active
".
If the operation is not enabled yet, this command will cause the switch on inhibit to be set
again instead.
At the same time the pulse inhibit is set (unless it is set already), i.e. the pulses of the
controller are inhibited.
If automatic brake operation is activated, the parameterised brake closing time is
observed: The system waits until the brake is applied before the pulse inhibit is set.
The motor becomes torqueless and coasts if it is not braked.
It is changed back to the device state "Switch on disabled
"
