Emergency-off
The drive is equipped with a hard-wired emergency-off circuit. When an emergency situation
occurs during operation, this safety feature ensures that the drive can be disconnected
without delay from the main power supply. If the
EMERGENCY-OFF
pushbutton has been
pressed while the drive is at standstill, the main power supply cannot be connected to the
drive, hence the drive cannot be started up.
The
EMERGENCY-OFF
pushbutton of the drive is part of the operator control panel (Fig. 9-1)
and features a latching switch action.

Initiating an emergency-off
To initiate an emergency-off, press the
EMERGENCY-OFF
pushbutton on the control
compartment door, or an external
EMERGENCY-OFF
pushbutton (if present) linked to the
emergency-off circuit.
When an emergency-off is initiated during drive operation, the following takes place:
- The MCB opens.
- The drive coasts down.
- The status line of the CDP control panel displays the message
Emerg Off.
- The DC link of the drive discharges.
Pressing the
EMERGENCY-OFF
pushbutton does not disconnect the auxiliary
power supply from the drive.
