Torque limit = 0

What does E2056 mean?

The IndraDrive MPx02 detects that the active torque limit has been set to zero. This effectively prevents the motor from generating any torque, causing the axis to stop or be unable to start motion, thereby protecting the mechanical system from unintended force.

• The torque limit parameter (e.g., S-0-0092 or other torque limit parameters) has been set to 0 Nm (or equivalent unit).
• An external control system (PLC) is commanding a zero torque limit, possibly due to a safety interlock or application logic.
• A safety or protection function within the drive or system is actively reducing the torque limit to zero.
• Incorrect parameter configuration or accidental modification of torque limits.

Click steps to track your progress.

1. 1

   Inspect the active torque limit parameter(s) in the IndraDrive MPx02, such as S-0-0092 (Torque command value limit), and verify its current value.

2. 2

   Review the master control system's program (PLC, CNC) to identify any logic that might be setting the drive's torque limit to zero.

3. 3

   Ensure that no safety functions or system interlocks are commanding the torque limit to zero, and that all necessary conditions for motor operation are met.

4. 4

   Increase the torque limit parameter to a suitable, non-zero value corresponding to the application's requirements, ensuring it is within the motor and drive capabilities.
