Safety Wiring - LinMot C1200 Installation Manual

9 Safety Wiring

The C1200 drives with the -1S option have internal safety functions:
Two Safety relays Ksr in series, which support the supply voltage for the motor
drivers. There are also two feedback contacts for each relay.
To enable the -1S drives both relays have to be switched on.
Minimal wiring:
- Connect X33.8 and X33.4 to 24VDC (from safety)
- Connect X33.7 and X33.3 to GND (from safety)
Attention: Never connect X33.8 and X33.4 to the logic supply of X4!
If an overvoltage protection is needed, it must be provided externally and
sized according the safety circuit of the machine!
Attention: The drop out time of the relays is depending on the external circuitry!
