Resetting the safety function

WARNING!
Make sure that the drive does not start accidentally. This can occur after the reset
of the safety function, if a level-triggered start command and the start enable signal
are on at the same time.
1. Return the emergency stop button [S61] or user-defined push button to the normal
position. For example, turn the emergency stop button [S61] until it releases.
2. Push the emergency stop reset button [S62] on the cabinet door for 0.1 ... 3 seconds.
The emergency stop reset button indicator light [S62] goes off, and the emergency stop
is deactivated.
3. If necessary, reset faults from the drive.
4. If necessary, close the main contactor/breaker.
5. Make sure that the drive receives the start signal.
6. You can now restart the drive.
For more information, see the hardware and firmware manuals.
Note: You must also reset the emergency stop safety relay [A61] or [A640] with the
emergency stop reset button [S62] each time after you energize the relay. If you do not
reset the relay, you cannot close the main contactor/breaker.
