ASDA-B2
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.
For example, after setting the electronic gear ratio properly, the moving distance of the
object is 1μm/pulse, which is easier to use.
