FAILURE 300-353: MITSUBISHI INVERTER ALARM MESSAGE
Always make sure you have the correct Frequency Inverter Parameter settings in the Inverter, especially when you have replaced the Inverter.
If unsure go to the Configuration Menu and select "Inverter Menu...", set the correct Machine Type and supply voltage; then load the
parameters from the washer computer to the Inverter again. If the correct parameters are not in the Frequency Inverter all sorts of Inverter
alarms may occur. See also the Frequency Inverter manual (available on request) for more info.

Motor overload See detailed explanation on following pages.
Fan stopped Repair the cooling fan (clean or replace if necessary).
Stall prevention See detailed explanation below.
Brake transistor Short circuit in brake transistor circuit. Power off immediately!
Replace the Inverter.
Ground fault Output overcurrent to ground.
1) Check the motorcable and motor for ground faults.
2) Disconnect the motorcable and try again. If you still have the error,
replace the Inverter.
Ext thermal relay External thermal relay (TRM module, see electrical scheme) for
motor protection tripped. TRM module was only used on certain
washers with MCB controller and A500 Inverter.
Option See detailed explanation below.
Corrupt memory Memory was overwritten too many times. Replace Inverter.
PU leave out See detailed explanation below.
Retry no over The max number of retries after fault reached. The actual Inverter error
code that causes the problem and which should be solved, is stored
just before Err 316 in the error log.
CPU Fault Communication error of built in CPU. Replace Inverter.
CPU Fault 6 Internal fault. If the fault is persistent, replace the Inverter.
CPU Fault 7 Internal fault. If the fault is persistent, replace the Inverter.
Instantaneous power Power failure between 15 and 100ms. Check for bad contacts in
failure the power circuit. Repair the power supply.
Under voltage Supply voltage too low. Check jumper P/+-P1.
Output phase failure Phase open detected on Inverter output. Check for bad contacts or
defect (open) motor windings.
Option slot 1 Problem with the option in slot 1 or option contact fault
Option slot 2 Problem with the option in slot 2 or option contact fault
Option slot 3 Problem with the option in slot 3 or option contact fault
PU short circuit Short circuit on the RS485 communication connector.
Check for short circuit in the communication cable.
24VDC short circuit Short circuit on the 24VDC power output (PC terminal).
Check for short circuit on the Inverter control terminals.
