(4) Wiring example for manual pulse generator/incremental
synchronous encoder
Wire the manual pulse generator/incremental synchronous encoder of differential
output type and voltage output type/open-collector type as follows.
Switch the input type of the Simple Motion module by "[Pr.89] Manual pulse
generator/Incremental synchronous encoder input type selection". It is
recommended to use the external 5V power supply (5VDC±5%) for the power
supply of the manual pulse generator/incremental synchronous encoder. When
using the external power supply, do not connect with the 5V terminal of the
Simple Motion module. When using the internal power supply, connect the 5V
terminal of the Simple Motion module and the 5V (+) of the manual pulse
generator/incremental synchronous encoder.
In either case, connect the 0V (-) of the manual pulse generator/incremental
synchronous encoder and the SG of the Simple Motion module. Do not use the
5V terminal of the Simple Motion module except for connecting the manual pulse
generator/incremental synchronous encoder. It may cause a failure. Also, do not
connect the manual pulse generator/incremental synchronous encoder whose
current consumption exceeds 200mA.
