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.
● Do not connect cables to the reserved pins.
● To determine the length of the encoder cable, consider voltage drop caused by the cable resistance
and signal attenuation caused by the distributed capacitance. It is recommended to use twisted-pair
cable of size 26AWG or above (as per UL2464 standard) and with a length within 10 m.
