Verify Motor Detection in Configuration

Navigate to MOD function → CfgServoMotor table and confirm the new motor entry matches the physically installed motor model.

Check that the motName parameter corresponds to the correct Heidenhain motor part number

Validate Motor Parameters

Review automatically populated motor parameters including rated current, torque constant, and encoder resolution in the CfgServoMotor table.

Incorrect motor parameters can cause servo instability or damage

Clear Informational Alarm

Acknowledge the alarm using the CE key as this is an informational message confirming successful motor registration.

Save the machine parameters after confirming correct motor detection

Check Cable Connection Status

Verify all motor encoder and power connections are secure at both motor and drive ends, ensuring proper EnDat communication.

Use the encoder diagnostic functions in MOD → Diagnosis → Encoder to verify EnDat communication quality

Verify Motor Identity Consistency

Compare the detected motor parameters with previous configuration backup to ensure the same motor was reconnected.

Mismatched motor types can cause unexpected machine behavior

Perform Reference Point Return

Execute reference point return for the affected axis using the REF function to re-establish machine coordinate system.

Monitor axis movement during reference return for any unusual behavior indicating motor mismatch

Access Drive Configuration

Navigate to MOD → CfgAxes and verify the drive assignment matches the physical drive module configuration.

Check the driveNo parameter corresponds to the correct PWM output channel

Validate Drive-Motor Pairing

Confirm in CfgServoMotor that the motor registration corresponds to the correct axis assignment in the drive configuration.

Incorrect drive-motor pairing can result in axis runaway conditions

Test Servo Loop Functionality

Use the servo diagnosis functions to verify proper torque control and position feedback for the re-detected motor.

Monitor following error values during slow axis movements to confirm proper servo tuning

Review System Boot Log

Check the PLC error log and system messages for any initialization errors that occurred during the motor detection process.

Look for EnDat communication errors or timeout messages in the diagnostic log

Verify Complete System Initialization

Ensure all axes show ready status in the axis status display and no additional configuration alarms are present.

Incomplete initialization may result in unpredictable machine behavior

Confirm Operational Readiness

Perform a complete machine reference cycle and verify all servo axes respond correctly to positioning commands.

Use manual axis movement at reduced feedrate to verify smooth operation before automatic operation

Check Software Version Status

Verify the TNC software version and motor parameter database version in MOD → System Info to confirm recent updates.

Document software versions before and after updates for troubleshooting reference

Compare Motor Parameters

Review the updated motor parameters in CfgServoMotor against previous settings to identify any significant changes.

Parameter changes may require servo tuning adjustments

Validate System Performance

Perform axis performance verification including acceleration tests and positioning accuracy checks with updated parameters.

Save a configuration backup after confirming proper operation with updated motor parameters
