E.3 STO function installation checklist
Before installing the STO, check the items described in the following table to ensure that the STO
function can be properly used.
Item
□
Ensure that the drive can be run or stopped randomly during commissioning.
□
Stop the drive (if it is running), disconnect the input power supply, and isolate the drive
from the power cable through the switch.
□
Check the STO circuit connection according to the circuit diagram.
□
Check whether the shielding layer of the STO input cable is connected to the +24 V
reference ground COM.
□
Connect the power supply.
□
Test the STO function as follows after the motor stops running:
 If the drive is running, send a stop command to it and wait until the shaft of the motor
stops rotating.
 Activate the STO circuit and send a start command to the drive. Ensure that the motor
does not start.
 Deactivate the STO circuit.
□
Restart the drive, and check whether the motor is running properly.
□
Test the STO function as follows when the motor is running:
 Start the drive. Ensure that the motor is running properly.
 Activate the STO circuit.
 The drive reports an STO fault (for details, see section 5.5.16 Fault handling). Ensure
that the motor coasts to stop rotating.
 Deactivate the STO circuit.
□
Restart the drive, and check whether the motor is running properly.
