2 SYSTEM CONFIGURATION
(10) Selection of the modules used in the extension base unit
The modules used in the extension base unit are selected according to the total
of current consumption of the modules, and peripheral devices (Manual pulse
generator, Incremental synchronous encoder, etc.) supplied by the Motion
controller and Motion controller internal power supply.
5VDC internal current consumption of shared equipments with PLC might be
changed. Be sure to refer to the MELSEC-Q series PLC Manuals.

• Power consumption of overall modules
I = 2.00 + 0.05 + 0.38 + 0.06
5V
= 3.595 [A]
System configuration is possible because of the total of current
consumption 3.595 [A] is the allowable value 4[A] or less.
POINT
Configure the system in such a way that the total current consumption at 5VDC of
all the modules is the allowable value 4 [A] or less.
