Error description 231-88C0

Error message

88C0 Max. nominal motor speed %1 exceeded

Cause of error

- Axis: Maximum feed rate is greater than the maximum motor speed (N-MAX) multiplied by the configuration datum distPerMotorTurn
- Spindle: Maximum spindle speed is greater than the maximum motor speed (N-MAX) multiplied by the gear transmission ratio
- The relationship between the line count of the position encoder and that of the motor encoder is faulty
- The N-MAX entry in the motor table is faulty
- Incorrect entry in the configuration datum motName
- EcoDyn: The selected feed rate exceeds the max. permissible voltage

Error correction

- Inform your service agency
- Check the N-MAX entry in the motor table
- Check the configuration data maxFeed, manualFeed and distPerMotorTurn
- Check the configuration data for spindle speed
- Check the STR column in the motor table and line count in the spindle parameter block (configuration datum "posEncoderIncr")
- Check all configuration data under CfgServoMotor
