4.5.3 Circuitry with use of the STO safety function [X3]
The safety function does not provide protection against electric shock, only against haz-
ardous movements. For intended use of the STO safety function (“Safe Torque Off ”),
observe the information in the documentation GDCP-CMMS-AS-G2-S1-...
If you need the integrated STO safety function in your application, you must remove the bridge between
Pin 1 and Pin 2 at the X3 interface to operate the motor controller Tab. 4.13.
Recommendation for initial start-up without safety equipment:
Minimum circuitry with emergency stop switching device and two-channel switch-off via the c ontrol
ports:
– R EL [ X3.2]
– DI N4 [X1.21].
Note
Loss of the safety function.
Lack of the safety function can result in serious, irreversible injuries, e.g. due to uncon-
trolled movement of the c onnected actuator technology. Bypassing of safety equipment
is impermissible.
• Make sure that no jumpers or the like can be used pa rallel to the safety wiring, e.g.
through the use of the maximum wire cross sections or appropriate wire end sleeves
with insulating collars.
• Use twin wire end sleeves for looping through lines between neighbouring devices.
