Emergency stop

Emergency stop characteristics :

Emergency stop and ready on connector:

Establishing a safety chain for monitoring the drives and other control components or a superordinate control unit usually requires a connection protected from wire breaks. The contact outputs (closer) P (X8(9)/3) and S (X8(9)/4) are used for this purpose. This closer establishes sequential switching for the mains module and the axis controller. When the unit is operating correctly, the contacts are closed (P and S are connected) and thereby indicate the readiness of the unit. If an error occurs or if the drive system is switched off, the readiness is not displayed and the chain is interrupted (see below).

The emergency stop input is used to activate or deactivate all drive controllers or an individual controller supplied by the mains module. In accordance with the safety chain described above, this input must be activated to power the motors. This occurs either via an external contact between X8(9)/5 and X8(9)/6 (as is shown in the figure below) or by applying voltage of between 15V and 24V to the input X8(9)/6 against GND (X8(9)/2). If the contact is opened or the voltage is removed from X8(9)/6 or routed to GND24V, the emergency stop sequence is processed, e.g. all motors of the connected drive controller are decelerated and switched off (no torque on the motor shaft); the ready contact drops.

!After an emergency stop: error E55 (even in OFF status) and O1="0". The current command is interrupted.

!The controller brakes the motor (P10 = braking time from 100% speed to 0%).

!When at a standstill, the controller is switched off and any idle holding brake is closed.

!Once the problem has been rectified, E55 must be acknowledged.

!The current command is continued after START.
