*1. Set "0: Differential-output type" in "[Pr.89] 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".
*2. Set the signal input form in "[Pr.24] Manual pulse generator/Incremental synchronous encoder input
selection".
*3. The 5 V DC power supply from the RD77MS 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 5 V DC.
Anything else may cause a failure.
