WARNING
Risk of injury due to electric shock.
• For the electrical power supply with extra-low voltages, use only PELV circuits
that guarantee a reinforced isolation from the mains network.
• Observe IEC 60204-1/EN 60204-1.
•
Only connect PELV circuits with an output current of max. 25 A. Otherwise,
use a separate external fuse: 25 A.

Cross-wiring
Cross-wiring makes it possible to set up a device compound consisting of up to 10
servo drives CMMT-AS. The different cross-wiring options are as follows:
–
Cross-wiring of I/O signals at the connection [X1A]
–
Cross-wiring of the mains and logic voltage supply without DC link coupling
–
Cross-wiring of the mains and logic voltage supply with DC link coupling

STO installation
Inputs and outputs for the safety sub-function STO
The 2-channel request for the safety sub-function is made via the digital inputs
#STO-A and #STO-B. The STA diagnostic output indicates whether the safe status
has been reached for the safety sub-function STO.
