State "Quick stop active"
This function state is active if quick stop has been activated by the user.
 Quick stop ( 388)
• The drive is brought to standstill within the deceleration time parameterised, irrespective of the
setpoint defined.
• If the quick stop is cancelled again by the user, a change-over to a setpoint-generating basic
function (e. g. "Speed follower") is effected, if requested.

Tip!
Quick stop can also be set as error response for many monitoring functions ("quick stop by
trouble"). Detailed information can be found in the chapter "Diagnostics & fault analysis".
The source from which the quick stop was activated is shown in a bit coded manner in
C00159 .
"Fault" state
This function state is active if a fault has occurred and the controller is in the "Fault active" or "Quick
stop by trouble active" device state.
• The function state can only be abandoned by acknowledging the error if the error is removed.
11.1.3 Interrupting/replacing states
An active function state cannot be interrupted or replaced by the activation of another function
state. However, the following exceptions apply:
• The "Initialisation" state replaces all other states.
• The "Fault" state can replace all other states except "Initialisation".
• The "Controller not ready" state can replace all other states except "Error" and "Initialisation".
• The "Quick stop active" state can replace all other states except "Initialisation", "Error" and
"Controller not ready".

Note!
For the encoderless motor control types (from software version V3.0) the following
applies:
The "Quick stop active" function state is also activated when DC-injection braking is
executed.
