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.

Note!

ƒ

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.
