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 output stages in the controller are inhibited and the speed/current controllers of
the motor control are reset.
The motor becomes torqueless and coasts, if it has not yet been in standstill.
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 function
(

– In the case of an operation with feedback, the actual speed is read out by the encoder
system.
– In the case of a sensorless vector control (SLVC), the actual speed from the motor
model of the motor control is used for the synchronisation.
C00158
provides a bit coded representation of all active sources/triggers of a controller
inhibit:
Tip!
The controller can also be enabled or inhibited via the and
toolbar
icons.
