10.5.2 Controller inhibit
If the controller inhibit is active, the power outputs are inhibited.
l The drive idles to standstill without torque.
l Keypad status display: Pulse inhibit c
l Status display of the controller: The green LED is blinking.

} Danger!
Do not use controller inhibit (DCTRL1-CINH) as emergency off.
The controller inhibit only inhibits the power outputs and does
not disconnect the controller from the mains!
The drive could restart any time.

HIGH
l Via terminal X3/28:
– LOW level at the terminal activates the controller inhibit (cannot be
inverted)
– HIGH level releases the controller again
l Via digital signal (linking C0410/10 with a signal source):
– LOW level at the signal source activates the controller inhibit (level
inversion is possible with C0411)
– HIGH level releases the controller again
l Via keypad (condition: C0469 = 1):
– s activates the controller inhibit
– u releases the controller again
l Via code C0040:
– C0040 = 0 activates the controller inhibit
– C0040 = 1 releases the controller again

) Note!
l The sources for controller inhibit are ANDed, i. e. the drive only
restarts when the controller inhibit is cancelled at all signal
sources.
l The restart begins with an output frequency of 0 Hz, i.e. if the
flying-restart circuit is not activated, still rotating masses can
lead to generative overload.
