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.

(Note-1): The 5V(P5)DC power supply from the Q170MCPU 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, be sure it is 5V voltage. Anything else may cause a failure.
(Note-2): Input type from manual pulse generator/incremental synchronous encoder switched by SEL.
Not connected: Voltage-output/open-collector type
SEL-SG connection: Difference-output type
CAUTION
(e) 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 (8)(a).)
