Thermal Overload / High Utilization

What does 11 mean?

This fault indicates either the unit's heatsink temperature has exceeded its permitted limit (sub-error 1-2) or the total utilization of both drives in dual-motor operation is excessively high (sub-error 4-5). Causes include high ambient temperatures, insufficient ventilation, or excessive mechanical load on the drives. Overheating and overutilization can lead to component degradation, reduced lifespan of the MOVIFIT unit, and potential permanent damage to power electronics if not resolved promptly.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Reduce the mechanical load on the connected drive(s) to decrease current draw and subsequent heat generation within the unit.

2. 4

   For dual-motor operation, review the application's duty cycle to minimize frequent starts/stops or high continuous loads that may exceed the unit's thermal capacity.
