Chapter 6 Control Modes of Operation

Revision April 2009
The electronic gear function provides easy travel distance ratio change. However, the over high
electronic gear ratio will command the motor to move not smoothly. At this time, the users can use low-
pass filter parameter to improve this kind of situation. For example, assume that the electronic gear ratio
is equal to 1 and the encoder pulse per revolution is 10000ppr, if the electronic gear ratio is changed to
0.5, then the motor will rotate one pulse when the command from external controller is two pulses.
For example, after the proper electronic gear ratio is set, the reference travel distance is 1
μ
m/pulse, the
machinery will become easier to be used.
