STO - Safety Torque Off function active.
The switch action of STO1/SCM1 and STO2/SCM2 (OPEN) - Reset the switch (ON) and cycle the power.
When Pr.06-44 = 1 and after STO error is cleared, it automatically resets.
When Pr.06-44 = 0 and after STO error is cleared, reset it manually.
Poor 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.
