Settings:

 

 

Please set electronic gear ratio when the servo drive is Off (Servo Off). As the wrong setting can cause motor to run chaotically (out of control) and it may lead to personnel injury, therefore, ensure to observe the following rule when setting P1-44, P1-45.

The electronic gear ratio setting range must be within: 1/50<N/M<200.

In terms of the servo drive which the firmware version is V1.018 or above, the electronic gear ratio can be set when the servo drive is On (Servo On).

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 μm/pulse, the machinery will become easier to be used.

Travel distance per pulse = T
