The differential input must be 5 V. Otherwise, unstable pulse input will occur on the servo
drive, resulting in the following situations:
● Pulse loss during pulse input
● Reference inverted during reference direction input
Connect 5V GND of the host controller to the GND of the servo drive to reduce noise
interference.

DI circuit
The circuits for DI1 to DI9 are the same. The following description takes DI1 circuit as
an example.
● The host controller provides relay output.
■ For use of an internal 24 V power supply of the servo drive
