U2 - 01
Shortage of inverter 1 power supply voltage
(Master)
Make a diagnosis of the relevant unit based on the following.
Shortage of power supply voltage
If the other units detect shortage of power supply voltage, power
supply voltage during operation may be unstable. Check the
power supply condition.
If a particular unit detects the error, operation of 52C may be
defective. Follow the
U2
flowchart.
Open phase of power supply
The wiring between power supply and inverter PCB may be
disconnected. Check that power supply is connected to terminal
block, terminal block is connected to PCB without broken wire or
disconnection, and reactor wiring is secured. If no abnormality is
found, follow the
U2
flowchart.
Defective capacitor in main circuit
P-N on the inverter PCB (electrolytic capacitor, power module)
may be damaged and short circuited. Operation of current limiting
relay may be defective or the wiring between the reactor and PCB
may be disconnected. Measure the resistance between P-N on
the inverter PCB and check for short circuit. If no abnormality is
found, follow the
U2
flowchart.
