4.5.3 Circuitry with use of the STO safety function [X3]
The safety function only provides protection against hazardous movements. For intended
use of the safety funct io n STO – “Safe Torque Off ” ( D escription of STO safety function,
GDCP-CMMS-ST-G2-S1-...).
If you need the integrated S TO 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. 4.12.
Recommendation for first commissioning without safety engineering:
Min imum circuitry with emergency stop switching device and two-chann el switch-off via the control ports:
– REL [ X3.2]
– DIN4 [X1.21] .
Please note
Loss of the safety function.
Lack of the safety function can result in serious, irreversible injuries, e.g. due to uncon-
trolled movements of the connected ac tuator tec hnology. Bypassing of safety equip-
ment is impermissible.
• Make sure that no jumpers or the like can be used parallel to the safety wiring, e.g.
through the use of the maximum wire cro ss se ctions or appropriate wire end sleeves
with insulating collars.
• Use twin wire end sleeves for looping through lines between neighbouring devices.
