Note
●
Be sure that the differential input is a 5V system, otherwise the input pulse of the driver is
unstable, which may result in the following situations:
(i) pulse loss when inputting the command pulse;
(ii) command reversal when inputting the command direction.
●
Be sure to connect GND of the host computer to GND of the drive to reduce noise
interference.
