Observe the following precautions when wiring the encoder:

Ground the servo drive and shielded layer of the servo motor reliably. Otherwise, the servo drive

will report a false alarm.

It is recommended to use twisted-pair cable sized 26AWG to 16AWG. The differential signals

shall be connected to two corresponding core wires in the twisted-pair cable. The wiring length

shall be as short as possible.

Do not connect cables to the reserved pins.

To determine the length of the encoder cable, consider voltage drop due to the cable resistance

and signal attenuation caused by the distributed capacitance. It is recommended to use twisted-

pair cable sized 26AWG or greater (as per the UL2464 standard) and shorter than 10 m. If the

cable is very long, use the cable of a larger size, as described in the following table.
