CAUTION
Do not use it in the combination of the teaching unit without deadman switch (A31TU-DN ) and
cable for teaching unit with deadman switch (Q170TUD3CBL3M). The protective function stops
working.
When the teaching unit (A31TU-D3 ) is not used in the Motion CPU (Q173CPUN-T/
Q172CPUN-T), connect the short-circuit connector for teaching unit (A31TUD3TM) to the control
panel side connector of the cable for teaching unit (Q170TUD3CBL3M). If it is not connected,
the emergency stop state of Motion CPU occurs, and the servomotor becomes coasting state.
