ERROR CODE FAULT DESCRIPTION DRIVE MODBUS REGISTER ACTION/CAUSE
E-01 Compressor Phase Over Current Reg.78|80 Bit0 1. Check the U/V/W connections on the drive side.
2. Check the compressor motor windings.
3. Check the compressor is operating within specified
limits.
4. Sensor on Drive not reading properly - Replace
Drive.
E-02 AC Input Over Current (SW) Reg.78|80 Bit1 1. Check that the line voltage is no more than 15%
below the specified voltage for the drive. Check the
line voltage for noise.
2. Check the compressor is operating within specified
limits.
3. If the problem persists, then it is possibly a drive
component issue. Replace the drive.
E-03 DC Bus Over Voltage (SW) Reg.78|80 Bit2 1. Check that the line voltage is no more than 15%
above the specified voltage for the drive.
2. Check the DC bus voltage if it is >385VDC.
3. Check the compressor is operating within the
specified limits.
4. If the problem still persists, then it is possibly a
drive component issue. Replace the drive.
E-04 DC Bus Under Voltage Reg.78|80 Bit3 1. Check that the line voltage is no more than 15%
below the specified voltage for the drive.
2. Check the DC bus voltage if it is <385VDC.
3. Check the compressor is operating within the
specified limits.
4. If the problem still persists, then it is possibly a
drive component issue. Replace the drive.
E-05 AC Input Over Voltage Reg.78|80 Bit4 1. Check that the line voltage is no more than 15%
above the specified voltage for the drive.
2. Check the DC bus voltage if it is >385VDC.
3. Check the compressor is operating within the
specified limits.
4. If the problem still persists, then it is possibly a
drive component issue. Replace the drive.
E-06 AC Input Under Voltage Reg.78|80 Bit5 1. Check that the line voltage is no more than 15%
below the specified voltage for the drive.
2. Check the DC bus voltage if it is <385VDC.
3. Check the compressor is operating within the
specified limits.
4. If the problem still persists, then it is possibly a
drive component issue. Replace the drive.
E-07 Inverter Desaturation Reg.78|80 Bit6 1. Check if all input cables are connected or any line
is missing.
2. Check that the line voltage is no more than 15%
below the specified voltage for the drive.
If the problem still persists, then it is possibly a
drive component issue. Replace the drive.

2. Check that the compressor is operating within
specified limits.
3. Check the mounting screws on the drive, make
sure they are tight. If the fault, persists replace the
drive.
E-13 PFC-IGBT Over Temp Reg.78|80 Bit12 1. Verify proper airflow over the heat-sink of the drive.
Remove any obstructions.
2. Check that the compressor is operating within
specified limits.
3. Check the mounting screws on the drive, make
sure they are tight. If the fault, persists replace the
drive.
E-14 Compressor Startup Fault Reg.78|80 Bit13 1. Cycle power on the drive.
2. If the problem persists replace the drive.
E-17 DC Voltage Low Reg.79|81 Bit0 1. Check that the line voltage is no more than 15%
below the specified voltage for the drive.
2. Check the DC bus voltage if it is <385VDC.
3. Check the compressor is operating within specified
limits.
