■ 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.
● Encoder frequency-division output
The encoder frequency‑division output circuit outputs differential signals through
the differential drive. Typically, this circuit provides feedback signals to the host
controller in a position control system. Use a differential or optocoupler receiving
circuit on the host controller side to receive feedback signals. The maximum
output current is 20 mA.
