Heidenhain · NC Control

What does 2196 F160 mean?

The I-MAX (peak current) of the motor for the displayed axis is incorrect. This indicates a mismatch between the configured peak current limit in the NC control and the motor's actual capabilities or application requirements.

Common Causes

  • I-MAX (peak current) parameter for the motor on the displayed axis is incorrectly configured.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the motor's peak current parameter setting (I-MAX) in the NC control for the specified axis against the motor nameplate data.

  2. 2

    Check for any mechanical binding, excessive load, or rapid acceleration requirements on the axis that could cause unusually high peak currents.

  3. 3

    Inspect the motor power stage and drive system for potential issues if the parameter is confirmed correct and the load is normal.

  4. 4

    Ensure the drive system is sized correctly to handle the expected peak torque requirements of the application for the specified axis.
