Electronic Gear Ratio
Electronic gear provides simple ratio change of travel distance. The high electronic gear ratio
would cause the position command to be 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 run one turn
every 10000 PPR. When electronic gear ratio is changed to 0.5, then every two pulses from the
command will be referred to one PUU of the motor encoder.
For example, after setting the electronic gear ratio properly, the moving distance of the object is 1
μm/pulse, which is easier to use.
