CAUTION
Do not use it in the combination of the teaching unit with deadman switch (A31TU-D3 ) and cable for
teaching unit without deadman switch (Q170TUDNCBL3M). The protective function stops working.
When the teaching unit (A31TU-DN ) 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 (Q170TUDNCBL3M). If it is not connected, the
emergency stop state of Motion CPU occurs, and the servomotor becomes coasting state.
