1. Error code definition
Control power supply error
2. Error definition and error detection method
No power is supplied to the control board from the power board.
3. Cause, check method and remedy
Measure the power-supply voltage. (TB01)
198 VAC - 264 VAC?
Yes
Measure the bus voltage (RYPN) during
INV board stop
248 VDC or higher?
Yes
Is the voltage
across pins 1 and 2 on
CN601 (MAIN board)
13 VDC ±10%?
No
Turn off the power supply, and leave it
turned off for at least 10 minutes.
Measure the bus voltage (RYPN).
20 VDC or lower?
Yes
(1) Check the wiring.
- Between CNVDC (INV board) and
CNDC (PS board)
- Between CN301 (PS board) and
CN601 (MAIN board)
(2) Check the fuse.
- F001 (INV board)
Turn on the power supply.
If the problem persists, replace
the power supply board.

the control board.
Turn off the power supply, and leave it
turned off for at least 10 minutes.
Measure the bus voltage (RYPN).
20 VDC or lower?
Yes
(1) Check the wiring.
- Between SC-P1 (INV board) and
SC-P2 (INV board)
- Between CN110 (PS board) and
SC-R/SC-T (INV board)
- Between FT001/FT002 (PS board) and
ACL
- CN401 (PS board) and CN301 (MAIN
board)
(2) Check the inverter circuit components.
See "8-10 Troubleshooting Inverter
Problems" for the check procedure.
Turn on the power supply.
If the problem persists, replace
the INV board.
If the problem persists, replace
