Thermal overload of the output stage or internal unit error

What does 11 mean?

The output stage of the unit has experienced thermal overload, or an internal error has occurred. This suggests that the operating temperature of the output stage is too high due to ambient conditions, inadequate heat dissipation, or excessive drive load, risking hardware damage.

• Output stage overheating due to sustained high load.
• Internal fault within the power module's heatsink monitoring.
• Fan failure or blockage affecting heatsink cooling.
• Parameter P0626 (output stage thermal model) inaccurate.
• Overcurrent condition leading to output stage stress.

Click steps to track your progress.

1. 1

   Lower the ambient temperature surrounding the unit.

2. 2

   Ensure proper ventilation around the unit to prevent heat build-up.

3. 3

   Reduce the mechanical load on the drive.

4. 4

   Reset the fault by switching off the DC 24 V supply voltage.
