1. Error Code
Abnormal bus voltage rise (Detail code 109)
2. Error definition and error detection method
If Vdc 400V is detected during inverter operation.
3. Cause, check method and remedy
(1) Different voltage connection
Check the power supply voltage on the power supply terminal block (TB1).
(2) INV board failure
If the problem recurs, replace the INV board.
In the case of 4220: INV board
In the case of 4225: Fan board
Refer to section -6- "Inverter (TJMU-A)" under part [4] Troubleshooting Principal Parts for error codes related to the
inverter.(page 251)
