Inverter Parameter Access Error (D9150); Inverter Status (D9151) - Mitsubishi Electric 700 Series Programming Manual

1.7.5

Inverter parameter access error (D9150)

Device No.
D9150
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.
1.7.6

Inverter status (D9151)

Device No.
D9151
The running status and operating status of the inverter are stored.
The corresponding bits are set according to the inverter status.
