(1) Example of wiring with an open collector output type encoder (24VDC)
For the wiring between the RD62 and an encoder, separate the power supply cables and the signal cables. The following
figures show its examples:

Because currents flow in
the same direction in the
shielded twisted pair cable,
canceling effect will be lost
and electromagnetic
induction may occur.
