Step2 ： Confirm CPLD Pulse Filter Setting
The CPLD filter inside the drive is used to filter the high-frequency clutter at the pulse input
port to prevent pulse interference. This filter is only valid for pulsed signals with a 50% duty
cycle. It should be noted that the filter frequency must be greater than the pulse frequency
before the gear, otherwise the effective pulse signal will be filtered.

Step3 ： Confirm the electronic gear ratio
Electronic gear numerator/ Electronic gear dinomerator=65536/number of external input pulses
Example: If the number of external input pulses is 10000 to make the motor rotate once, the
electronic gear ratio should be 65536:10000, the numerator of the electronic gear should be set
to 4096, and the denominator of the electronic gear should be set to 625.
Step4
： Basic parameter settings before running
After setting the parameters of the first three steps, you can check whether there is data in the pre-
gear pulse data, and whether the pre-gear pulse frequency is consistent with the pulse frequency
sent by the host device. After confirmation, the working mode and the control word can be set to
run the motor. The running direction of the motor can be adjusted by modifying the speed, position
and direction control.

Other function
Pulse filter coefficient ： Set the filter coefficient so that the externally input pulse command can be
smoothly input to the drive. Adjusting this parameter can reduce the motor vibration caused by the
high electronic gear ratio setting or the lack of acceleration and deceleration of the pulse command.
If the coefficient is set too high, the motor response may be slowed down.
。 The filter coefficient can
only be adjusted when the motor is stopped
