Mitsubishi Electronics FR-A700 Inverter parameter access error D9150, Inverter status D9151

Inverter Status Monitoring, Special Registers for Control

1.7.5Inverter parameter access error (D9150)

Device No.	Name	Data Access Enable
		Condition
D9150	Inverter parameter access error	Always

If any value outside the setting range is written during parameter write, set frequency write, parameter clear, etc. from the sequence program of the inverter, or if write is performed when write is disabled, a write alarm occurs and the corresponding alarm code is stored into D9150.

<Parameter>

The parameter No. + H8000 is stored into D9150.

Example: If an error occurs during write of Pr.0 Torque boost, H8000 (H0 + H8000) is stored into D9150.

If an error occurs during write of Pr.10 DC injection brake operation frequency, H800A is stored into D9150.

<Operation mode, set frequency, alarm definition batch clear, all parameter clear>

HFFFF is stored into D9150. (Normal 0)

POINT

If write is completed normally after error occurrence, D9150 is not cleared (D9150 data is held at error occurrence). When using D9150 to stop operation, etc., the user must clear it.

1.7.6Inverter status (D9151)

Device No.	Name	Data Access Enable
		Condition
D9151	Inverter status	Always

The running status and operating status of the inverter are stored. The corresponding bits are set according to the inverter status.
