Make sure the differential input is 5 V. Otherwise, input pulses of the servo drive are unstable,
which will cause:
•
When the reference pulse is input, pulse loss occurs.
•
When reference direction is input, the direction will reverse.
The 5V ground of the host controller must be connected to GND terminal of the servo drive to
reduce noise interference.

Encoder frequency dividing output circuit outputs differential signals via differential drive.
Normally, the encoder output circuit provides feedback signals to the host controller. The
circuit and the host controller together form a closed-loop position control system. A differential
or optocoupler circuit shall be used in the host controller to receive feedback signals. The
maximum output current is 20 mA.
