Terminal descriptions
Encoder pulse input
Use shielded twisted pairs to match the high input frequency.
● To reduce noise interference, connect the reference ground of the external
encoder to the GND of the drive. Use shielded cables and connect the shield to the
CN7 terminal enclosure.
● The input mode of the external encoder is differential input.
● The maximum pulse frequency supported by a phase A/B linear encoder is 4 Mbps.
● The pulse input terminal of a phase A/B encoder supports open circuit detection.
Suppose the current consumed by the motor encoder is 200 mA, you can select the
cable based on the following recommendations.
