Why does my Lenze AC Tech Controller 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 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 Controller?
A Low DC Bus Voltage Fault in your Lenze AC Tech Controller is caused by line voltage that is too low.
What to do if Lenze AC Tech SF430 Controller displays a Control Fault?
If your Lenze AC Tech Controller displays a Control Fault, it may be due to a blank EPM or an EPM with corrupted data. Perform a factory reset using Parameter 48 - PROGRAM SELECTION.
How to resolve Incompatibility Fault on Lenze AC Tech Controller?
An Incompatibility Fault on your Lenze AC Tech Controller indicates that an EPM with an incompatible parameter version has been installed. You can either exchange the EPM or perform a factory reset (Parameter 48) to change the parameter version of the EPM to match the parameter version of the drive.
What does Single-phase Fault mean on Lenze AC Tech SF430?
A Single-phase Fault on your Lenze AC Tech Controller means that single-phase input power has been applied to a three-phase drive.
Why does my Lenze AC Tech Controller show a Start Fault?
A Start Fault on your Lenze AC Tech Controller occurs when a start command was present when the drive was powered up. You must wait 2 seconds after power-up to apply the Start command if START METHOD is set to NORMAL.
What does External Fault mean on Lenze AC Tech SF430?
An External Fault occurs on your Lenze AC Tech Controller when TB-13A and/or TB-13C is set as an External Fault input and TB-13A and/or TB-13C is open with respect to TB-2. Refer to Parameter 10 or 12.
What causes a Data Fault in Lenze AC Tech SF430?
A Data Fault in your Lenze AC Tech Controller indicates that user data and OEM defaults in the EPM are corrupted.
What does Serial Fault mean on Lenze AC Tech SF430 Controller?
A Serial Fault indicates that the watchdog timer has timed out, meaning the serial link has been lost on your Lenze AC Tech Controller.
