STO Loss 1 (STL1)
STO1–SCM1 internal loop detection error.
STO1 and SCM1 short circuit lines are not connected - Connect the short circuit line.
Hardware failure - After you make sure all the wiring is correct, if STOL fault still exists after cycling the power, check drive hardware.
Bad connection of the IO card -
Check if the PIN of IO card is broken.
Check if the IO card connects to the control board correctly, and if the screws are tightened well.
