4.1.4 Enable/inhibit inverter
The C00002/16 = "1: On / start" device command enables the inverter, provided that no other
source of an inverter inhibit is active.
The C00002/16
= "0: Off / ready" device command inhibits the inverter again, i.e. the power output
stages in the inverter 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

• 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 inverter can also be enabled or inhibited via the and toolbar icons.
