6.4 Controller i nhibit
If the controller inhibit is active, the power outputs are inhibited.
ƒ The drive idles to standstill.
ƒ Status display of keypad: Pulse inhibit
ƒ Status display at the controller: The green LED is blinking.
Danger!
Do not use the function ”Controller inhibit” (DCTRL1-CINH) as
emergency-off. The controller inhibit only inhibits the power
outputs and does not separate the controller from the mains!
The drive could start any time again.

0 Ctrl inhibit Controller inhibited
1 Ctrl enable Controller enabled
Via terminal X5/28:
ƒ LOW level at the terminal activates the controller inhibit (not
invertible)
ƒ HIGH l evel enables the controller again
Via the keyboard of the keypad (condition: C0469 = 1):
ƒ activates the controller inhibit
ƒ enables the controller again
Via code C0040:
ƒC0040=0activatesthecontrollerinhibit
ƒC0040=1enablesthecontrolleragain
Note!
ƒ The sources for controller inhibit are AND’ed, i.e. the drive only
starts again if the controller inhibit is deactivated for all signal
sources.
ƒ The restart begins with zero speed, i.e. with the centrifugal
masses still rotating an overcurrent may occur if the flying
restart circuit is not active.
