⚫ STO means that Channel 1 and Channel 2 enable Safe Torque Off at the same time.
⚫ STO1 indicates that the difference between Channel 1 and Channel 2 is too large, and Channel 1
is active. Check the external wiring.
⚫ STO2 indicates that the difference between Channel 1 and Channel 2 is too large, and Channel 2
is active. Check the external wiring.
⚫ STL1 indicates Channel 1 internal circuit detected abnormal.
⚫ STL2 indicates Channel 2 internal circuit detected abnormal.
⚫ STO1–SCM / STO2–SCM ON: means STO1–SCM / STO2–SCM input voltage > 15 V
DC
