Over-torque

Kone · Frequency Inverter

What does 6 mean?

This error indicates that the motor torque has exceeded a predefined maximum limit set in the drive. This typically occurs when the mechanical load on the motor is too high, or acceleration/deceleration ramps are configured too aggressively, demanding excessive torque.

Common Causes

  • Mechanical overload on the motor, exceeding its rated capacity.
  • Incorrectly set torque limits or overload thresholds in the drive's parameters.
  • Physical obstruction or binding within the mechanical system preventing free movement.
  • Acceleration or deceleration ramps set too aggressively for the connected load.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Reduce the mechanical load on the motor to ensure it operates within its rated torque capacity.

  2. 2

    Review and adjust the drive's torque limit parameters (e.g., maximum output torque, overload threshold) to appropriate values for the application.

  3. 3

    Inspect the mechanical system for any signs of binding, excessive friction, or physical obstructions.

  4. 4

    Increase the acceleration or deceleration ramp times in the drive parameters to reduce peak torque demands during transitions.
