4.1.5 Enable/Inhibit controller
The C002/16 = "1: : On / start" device command enables the controller, provided that no other sour-
ce of a controller inhibit is active.
The
C002/16 = "0: Off / ready" device command serves to inhibit the controller, i.e. the power out-
put stages in the controller are inhibited and the speed/current controller of the motor control is re-
set.zurückgesetzt.
• 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 C990 , the flying restart function parameterised in
C991 is used for the synchronisation to the rotary or standing drive.  Flying restart function
