Description

NOT READY TO
START

During initialisation, the controller is not yet ready for operation. Afterwards it
automatically switches to the "READY TO START" device status.

SWITCH−ON INHIBIT The controller is inhibited and waits for command 2 (standstill).

READY TO START

The controller is inhibited and waits for command 3 (switch on).

SWITCHED ON

The controller is inhibited and waits for command 4 (enable operation).

OPERATION
ENABLED

The controller is enabled. In this device status the pulse inhibit can be set automatically.

FAULT REACTION
ACTIVE

A fault (TRIP) was recognised and a time−based fault−dependent response has been
initiated.

FAULT

The controller is in the "FAULT" (TRIP) device status.

QUICK STOP ACTIVE The "quick stop" (QSP) command was given in the device status "OPERATION ENABLED". A

controlled deceleration (quick stop ramp) is executed. After deceleration the device
changes automatically to the state "SWITCH−ON INHIBIT".
