activation switch deactivates the STO. Any faults generated must be reset before restarting.
The STO function has a redundant architecture, that is, both channels must be used in the safety function implementation.
The safety data given is calculated for redundant use, and does not apply if both channels are not used.
WARNING! The STO function does not disconnect the voltage from the main and auxiliary circuits of the drive.
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
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. Validation instructions of the STO function can be found in the drive hardware
manual.
