：
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.
6.5.2 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.

Clear pulse：The clear pulse function in DIN can clear the number of pulses that the drive has received but not completed, and
the deviation pulse can be adjusted during operation。When DIN defines a clear pulse and the actual input changes from 0 to 1,
use the rising edge to clear the deviation between the pre-gear pulse data and the post-gear pulse data.
Position fine-tuning: Position fine-tuning is used to set the position data to be fine-tuned in pulse mode, and speed fine-tuning is
used to set the speed of fine-tuning when position fine-tuning is performed. The fine-tuning function can be used during pulse
positioning operation in the following two ways:
Method 1: To achieve positive and negative direction fine-tuning by directly setting the position fine-tuning data value. When the
value of position fine-tuning is greater than 0, positive fine-tuning is performed; when the value of position fine-tuning is less than
0, negative fine-tuning is performed. When position fine-tuning and velocity fine-tuning are set to 0, the fine-tuning function is
disabled. Under this control mode, DIN does not define the positive/negative fine tuning function, and position fine tuning and
speed fine tuning data are not saved when power fails.
Method 2: Define positive fine-tuning and negative fine-tuning functions through DIN to control fine-tuning, position fine-tuning
and speed fine-tuning data can be saved after power failure.
