If a separate power supply is applied to the manual pulse generator/incremental synchronous
encoder, be sure it is 5V voltage. Anything else may cause a failure.
Always wire the cables when power is off. Not doing so may damage the circuit of modules.
Wire the cable correctly. Wrong wiring may damage the internal circuit.
5V terminal is the power supply for the manual pulse generator/incremental synchronous
encoder. Do not apply a voltage and do not use it for other purposes.

CAUTION
(d) Connection of manual pulse generator/incremental synchronous encoder
Manual pulse generators/incremental synchronous encoders of the voltage-
output/open-collector type and differential-output type can be connected.
Both connection methods are different. (Refer to this section (9)(a).)
