•
In case a manually operated activation switch is used, the switch must be of a type that
can be locked out to the open position.
•
The contacts of the switch or relay must open/close within 200 ms of each other.
•
A CPTC-02 thermistor protection module can also be used. For more information, see
the module documentation.
■
Cable types and lengths
•
Double-shielded twisted-pair cable is recommended.
•
Maximum cable lengths:
•
300 m (1000 ft) between activation switch [K] and drive control unit
•
60 m (200 ft) between multiple drives
•
60 m (200 ft) between external power supply and first control unit
Note:
A short-circuit in the wiring between the switch and an STO terminal causes a
dangerous fault. Therefore, it is recommended to use a safety relay (including wiring
diagnostics) or a wiring method (shield grounding, channel separation) which reduces or
eliminates the risk caused by the short-circuit.
Note:
The voltage at the STO input terminals of the drive must be at least 13 V DC to be
interpreted as “1”.
The pulse tolerance of the input channels is 1 ms.
■
Grounding of protective shields
•
Ground the shield in the cabling between the activation switch and the control unit at
the control unit only.
•
Ground the shield in the cabling between two control units at one control unit only.
