Settings：
If the setting is wrong, the servo motor will easily have sudden
unintended acceleration.
Please follow the rules for setting:
The setting of pulse input:
Range of command pulse input: 1／50＜Nx／M＜25600
NOTE
1） The setting value cannot be changed when Servo ON neither in
PT nor in PR mode.
Electronic gear provides simple ratio change of travel distance. The high electronic gear ratio
would cause the position command to be the stepped command. S-curve or low-pass filter can
be used to improve the situation. When electronic gear ratio is set to 1, the motor will turn one
cycle for every 10000PUU. When electronic gear ratio is changed to 0.5, then every two pulses
from the command will be refer to one PUU of motor encoder.
