Danger!
Do not use the "controller inhibit" function (DCTRL1−CINH) for
emergency−off. The controller inhibit only inhibits the power
outputs and does not disconnect the controller from the mains!
The drive could start again any time.

Via terminal X5/28:
ƒ A LOW level at the terminal inhibits the controller (cannot be inverted)
ƒ A HIGH level re−enables the controller
Via the keys of the keypad (if C0469 = 1):
ƒ
s inhibits the controller
ƒ
u re−enables the controller
Via code C0040:
ƒ C0040 = 0 inhibits the controller
ƒ C0040 = 1 re−enables the controller
)
Note!
ƒ The sources for controller inhibit are ANDed, i.e. the drive only
restarts if the controller inhibit signals of all signal sources
have been eliminated.
ƒ The restart starts with zero speed. If centrifugal masses are
still rotating, this can lead to an overcurrent.
