Notes:
•
If stopping by coasting is not acceptable, stop the drive and machinery using the
appropriate stop mode before activating the STO.
•
The STO function overrides all other functions of the drive.
Wiring

The safety contacts must open/close within 200 ms of each other.
Double-shielded twisted-pair cable is recommended for the connection. The maximum
length of the cabling between the switch and the drive control unit is 300 m (1000 ft). Ground
the shield of the cable at the control unit only.
Validation

EN
To ensure the safe operation of a safety function, a validation test is required. The test must
be carried out by a competent person with adequate expertise and knowledge of the safety
function. The test procedures and report must be documented and signed by this person.
DA
Validation instructions of the STO function can be found in the drive hardware manual.
