VFD ERROR SCREENS AND CODES
VFD Error Screens
Voltage Range Error
The VFD is capable of handling a wide range of input power. The voltage range is:
230V models: 200
–230V +/-10% (180–253V)
460V models: 380
–460V +/-10% (342–506V)
If input source power is outside of these ranges, the error on the following screen will appear. The VFD is protected from voltage fluctuations within the specified voltage range.
If a machine is plugged into a power source that is above the machine’s maximum voltage capability (for example, 230V model plugged into a 460V generator), this will damage the VFD and void the warranty.
Cooling Fan Error
The X4 VFDs are equipped with one or two electric fans mounted on the back of the VFD’s cooling fins (heat sink – HS). When the VFD is plugged in, it will run a self-diagnostic to make sure all internal components are operational and to check the cooling fans. If the fans fail to spin, the error on the following screen will appear. This could happen because of debris jamming the fan blades, heavy contamination, or water inhibiting the power that the fan needs to run. In the event of a cooling fan error, unplug the machine and inspect, clean, and check for free movement of the fan blade.

EXPLANATION
Problem with the heat sink fan.
Problem with the internal fan. This occurs only on Size 4 and 5 models. All other models display a fan error warning. Note that this is lack of fan control, so the fan can be spinning and this fault will still occur. This can happen if the fan is on and should not be, or if the fan feedback signals are obstructed from getting to the control board.

GLOSSARY
Line Voltage
This is the voltage of a power source when it has no load applied to it. It can also be called “nominal voltage” as the voltage expressed is usually a guideline voltage.
Load Voltage
This is the voltage of a power source when a load has been applied to it. As a load is applied to the power source, the resistance of the line is easier to examine. When a voltage-measuring device such as a multimeter is used during operation of the machine, you can clearly see that the voltage drops as soon as a load is applied and rises back when the load is taken off.

VFD
A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives, or inverter drives. Because the voltage is varied along with frequency, these are sometimes also called variable voltage variable frequency
(VVVF) drives.
