Observe the following precautions when wiring the encoder:
1. Servo drive and shield at servo motor side must be properly grounded. Otherwise, the
servo drive will report false error.
2. It is recommended that twisted-pair cables of size from AWG26 to AWG16 be used. The
cables shall not exceed 20 m.
3. Do not connect wires to the reserved pins.
4. 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 AWG26 or above (as per UL2464 standard)
and with a length within 10 m. The following table lists the recommended cable sizes.
