(Note-2): The manual pulse generator or incremental synchronous encoder that consumes less than 0.2[A] of 
current can be connected to the internal I/F connector. 
(Note-3): 5VDC internal current consumption of shared equipments with PLC might be changed. 
Be sure to refer to the MELSEC-Q/L series PLC Manuals. 
(Note-4): Be sure to use the power supply module within the range of power supply capacity. 
(Note-5): Battery Q6BAT is not attached to Battery holder unit Q170DBATC. Please purchase it separately. 
(Note-6): Be sure to use the cable for forced stop input (sold separately). The forced stop cannot be released 
without using it. 
Cable for forced stop input is not attached to the Motion CPU module. Please purchase the cable for 
length according to system separately. 
(Note-7): These modules can be used in Q172DLX. It cannot be controlled using Q173DPX. 
(Note-8): Please contact your nearest Mitsubishi sales representative for the cable of less than 30m(98.43ft.).
