POINT
Configure a system by choosing the motion modules and MELSEC-A series I/O modules so that the sum
of 5VDC consumed currents of the motion modules, MELSEC-A series I/O modules, synchronous
encoders and manual pulse generators connected to the main base unit is within 5 (A) for the
A172SHCPUN or 3 (A) for the A171SHCPUN.
