Why does my Leeson SPEEDMASTER SM display a Current Overload Fault?
A Current Overload Fault in your Leeson Inverter typically means that the VFD is undersized for the application or there's a mechanical problem with the driven equipment.
What causes a High Temperature Fault on a Leeson SPEEDMASTER SM?
A High Temperature Fault can be triggered if the ambient temperature is too high, or if the cooling fan has failed (if the inverter is equipped with one).
What does it mean when my Leeson SPEEDMASTER SM Inverter shows a Remote Keypad Fault?
A Remote Keypad Fault indicates that the communication link between the drive and the optional Remote Keypad has been lost. Check the wiring and look for any noise that might be interfering with the signal.
What causes an Incompatibility Fault in a Leeson SPEEDMASTER SM?
An Incompatibility Fault occurs when an EPM with an incompatible parameter version has been installed. You can either remove the EPM or perform a factory reset (Parameter 48) to align the parameter version of the EPM with that of the drive.
How to fix a Control Fault on a Leeson SPEEDMASTER SM?
A Control Fault happens when a blank EPM, or an EPM with corrupted data, is installed. To resolve this, perform a factory reset using Parameter 48 - PROGRAM SELECTION.
Why does my Leeson Inverter show an External Fault?
An External Fault occurs if one of the TB-13 terminals is set as an External Fault input and that terminal is open with respect to TB-11. Refer to Parameters 10, 11 and 12 for configuration details.
Why does my Leeson Inverter show a Low DC Bus Voltage Fault?
A Low DC Bus Voltage Fault indicates that the line voltage is too low.
What to do if Leeson Inverter shows a Start Fault?
A Start Fault means a start command was present when the drive was powered up. If START METHOD is set to NORMAL, wait 2 seconds after power-up to apply the Start command.
What does it mean when my Leeson SPEEDMASTER SM displays a Data Fault?
A Data Fault indicates that user data and OEM defaults in the EPM are corrupted.
What causes an EPM Fault on a Leeson SPEEDMASTER SM Inverter?
An EPM Fault indicates that the EPM is either missing or damaged.
