To Next PageTo Next PageWhy does my Lenze AC Tech SF210 show a Current Overload Fault?
A Current Overload Fault in your Lenze AC Tech Controller indicates that the VFD is undersized for the application or there is a mechanical problem with the driven equipment.
What causes an Output Transistor Fault in Lenze AC Tech SF210 Controller?
An Output Transistor Fault in your Lenze AC Tech Controller can be triggered by a phase-to-phase or phase-to-ground short circuit on the output, a failed output transistor, boost settings that are too high, or an acceleration rate that is too fast.
What causes a Low DC Bus Voltage Fault in Lenze AC Tech SF210?
A Low DC Bus Voltage Fault in your Lenze AC Tech Controller is caused by line voltage that is too low.
