2 SYSTEM CONFIGURATION
Control panel
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 (Q173HCPU-T/Q172HCPU-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.
(b) Connection between the teaching unit (A31TU-DN ) and
Motion CPU (Q173HCPU-T/Q172HCPU-T)
There are following two connecting method.
• When the connector is connected to the control panel.
• When the connector is connected directly in the control panel.
1) When the connector is connected to the control panel.
a) Connect the cable for teaching unit (Q170TUDNCBL3M) between
the TU connector of Motion CPU (Q173HCPU-T/Q172HCPU-T) and
control panel. (Refer to the exterior dimensions of "APPENDIX 1.3
Cable for the teaching unit" and "APPENDIX 2.7 Connector", when
it is fit to the control panel.)
b) Connect the teaching unit (A31TU-DN ) to the cable for teaching
unit (Q170TUDNCBL3M) connected to the control panel.
c) When the teaching unit (A31TU-DN ) is not used, connect the
short-circuit connector for teaching unit (A31TUD3TM) to the control
panel side connector of the cable for teaching unit
(Q170TUDNCBL3M).
Connection example between the cable for teaching unit (Q170TUDNCBL3M) is
shown below.
