How to Make a Servo Motor Rotate Above 2200 RPM Using the ST-C01?

First, we need to consult the manual:

If parameter F-09 is set to the number of pulses required for the motor to rotate one revolution divided by 10, then the value displayed on the ST-C01 corresponds directly to the RPM.

If parameter F-09 is not set this way, then the actual speed is calculated using the formula: RPM / ST-C01 displayed value = (F-09 * 10) / Number of pulses per revolution set in the driver.

Given that this simple controller's display value can only be set up to 999, it is necessary to increase the value of parameter F-09. The specific multiplier should be adjusted according to the formula above.

When using A6-RS series servo motors, some customers report an inability to accelerate beyond 2200 RPM. This requires the wiring method shown in the provided diagram, which can also be found in the manual.

Assuming the servo motor's default setting is 10,000 pulses per revolution, and applying the formula: by setting parameter F-09 to 6000, a display value of 500 on the controller will correspond to 3000 RPM.
