STO input state
Corresponding fault
H1 and H2 opened
simultaneously
The STO function is triggerd, and the drive stops running.
Fault code:
40: Safe torque off (SAFE)
H1 and H2 closed simultaneously
The STOP function is not triggered, and the drive runs
properly.
One of H1 and H2 opened, and
the other closed
The STL1, STL2, or STL3 fault occurs.
Fault code:
38: Channel H1 exception (STL1)
39: Channel H2 exception (STL2)
40: Channel H1 and H2 exceptions (STL3)
2. STO channel delay description
The following table describes the trigger and indication delay of the STO channels.
STO mode
STO trigger and indication delay
1), 2)
STO fault: STL1
Trigger delay < 10 ms
Indication delay < 280 ms
STO fault: STL2
Trigger delay < 10 ms
Indication delay < 280 ms
STO fault: STL3
Trigger delay < 10 ms
Indication delay < 280 ms
STO fault: SAFE
Trigger delay < 10 ms
Indication delay < 100 ms
1) STO function trigger delay: Time interval between triggering the STO function and switching off the
drive output
2) STO indication delay: Time interval between triggering the STO function and STO output state

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.
□
COM Check whether the shielding layer of the STO input cable is connected to the
+24 V reference ground COM.
