E8040

Torque/force actual value limit active

Indramat · IndraDrive MPx02

What does E8040 mean?

The actual torque or force produced by the motor is being limited by a configured parameter in the IndraDrive MPx02. This warning indicates that the motor is operating at its maximum allowed torque/force, potentially due to excessive load or a low-set limit, preventing further increase in output.

Common Causes

  • The mechanical load on the motor requires more torque/force than the configured limit (e.g., S-0-0092, Torque command value limit).
  • The torque/force limit parameter is set too low for the application's needs.
  • The motor is approaching its maximum continuous or peak torque capability, leading to automatic limitation.
  • Friction, binding, or unexpected resistance in the mechanical system.
  • Incorrect scaling of torque/force feedback in the drive.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Monitor the actual motor torque/force output (if available via diagnostics) and compare it to the drive's configured torque/force limit (e.g., S-0-0092).

  2. 2

    Assess the mechanical load on the motor and determine if it is unexpectedly high or if there is binding/friction in the system.

  3. 3

    If the application requires higher torque/force, and the motor/drive system can safely provide it, increase the torque/force limit parameter in the IndraDrive MPx02.

  4. 4

    Verify that the motor's nominal torque and current parameters in the drive match the motor nameplate and application requirements.

  5. 5

    Check for any external factors or process variations that might be increasing the load beyond normal operating conditions.
