(Note-1),

(Note-1): Set "0: Differential-output type" in " Manual pulse generator/Incremental synchronous encoder input type
selection" if the manual pulse generator/Incremental synchronous encoder of differential-output type is used.
The default value is "1: Voltage-output/open-collector type".
(Note-2): Set the signal input from in " Manual pulse generator/Incremental synchronous encoder input selection".
(Note-3): The 5VDC power supply from the QD77MS 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.
