4.1.5 Enable/Inhibit controller
The C00002/16 = "1: On / start" device command enables the controller, provided that no other
source of a controller inhibit is active.
The
C00002/16 = "0: Off / ready" device command inhibits the controller again, i.e. the power out-
put stages in the controller are inhibited and the speed/current controllers of the motor control are
reset.
• The motor becomes torqueless and coasts down.
• When the controller is inhibited, the status output bCInhActive of the
LS_DriveInterface system
block is set to TRUE.
• When the controller inhibit request is reset, the drive synchronises to the actual speed. For this
purpose,
• If the flying restart circuit is activated in C00990 , the flying restart function parameterised in
C00991 is used for the synchronisation to the rotary or standing drive.  Flying restart func-
tion ( 148)
• In the case of an operation with feedback, the actual speed is read out by the encoder system.

Tip!
• The controller can also be enabled or inhibited via the and toolbar icons.
• C00158 provides a bit coded representation of all active sources/triggers of a controller
inhibit.
4.1.6 Activate/deactivate quick stop
The C00002/17 = "1: On / start" device command activates the quick stop function, i.e. the motor
control is separated from the setpoint selection, and within the deceleration time parameterised
in C00105 the motor is brought to a standstill (n
act
= 0).
• The motor is kept at a standstill during closed-loop operation.
• A pulse inhibit (CINH) is set if the auto-DCB function has been activated via
C00019 .
The C00002/17 = "0: Off / ready" device command deactivates the quick stop again, provided that
no other source of a quick stop is active.

Tip!
C00159 displays a bit code of active sources/causes for the quick stop.
