How to Change the Pulses Per Revolution for the A6 Series Servo Motor?

The Pulses Per Revolution (PPR) for a servo motor refers to the number of electrical pulse signals required for the motor to complete one full rotation. This is a critical parameter for controlling the motor's rotational accuracy. In the drive's manual, this parameter is listed as C00.02, with a default value of 10000.

The value of C00.02 can be modified using the following three methods:

Using the Configuration Software

1. Click on "Parameter Management".
2. Click on "C00 Group Parameters".
3. Check the box for C00.02 and enter your desired value in the setting field.
4. Click "Write Selected".

Finally, power cycle the drive for the change to take effect.

Modifying via 485 Command

The corresponding 485 address for C00.02 is 0002. Send the following command:

01 06 00 02 xx xx CRC CRC (Where xx xx represents the hexadecimal value of the desired number. For example, 5000 in hexadecimal is 13 88).

Note: Ensure the motor enable is not activated when modifying. If you need to save the parameters permanently, it is recommended to send the save command before writing the modification:

01 06 0A 05 00 01 CRC CRC

Modifying via the Drive Panel Buttons

After powering on the drive, when the panel defaults to displaying P-rd, proceed as follows:

• Press the below button once. The panel will display C00. blinking.

• Press the SET button again. The panel will display C00.00 blinking, indicating the current parameter being set is C00.00.

• Press the UP button twice to increase the value; the panel will display C00.02.

• Press the SET button again. The panel will now display the lower four digits of the C00.02 value (For detailed information about high, middle, and low values, please refer to page 182 of the manual).

• Use the UP and DOWN buttons to adjust the value.

• After setting the value, press the SET button to confirm.

Finally, power cycle the drive for the change to take effect.
