(b) Interface between manual pulse generator/incremental synchronous
encoder (Voltage-output/open-collector type)
(Note-1): Set "1: Voltage-output/open-collector type" in " Manual pulse generator/Incremental synchronous
encoder input type selection" if the manual pulse generator/Incremental synchronous encoder of voltage-
output/open-collector type is used.
The default value is "1: Voltage-output/open-collector type".
(Note-2): Set the signal input form in " Manual pulse generator/Incremental synchronous encoder input selection".
(Note-3): The 5VDC power supply from the Simple Motion module must not be used if a separate power supply is applied
to the manual pulse generator/Incremental synchronous encoder.
If a separate power supply is used, use a stabilized power supply of voltage 5VDC.
Anything else may cause a failure.
(Note-4): Be sure to connect the 0 V (-) of the manual pulse generator/incremental synchronous encoder and the SG of
the Simple Motion module.
