Mitsubishi Electronics 700 Series, FR-A700 Operation mode setting write D9143 Data are as follows

Inverter Status Monitoring, Special Registers for Control

(1)Operation mode setting write (D9143) Data are as follows:

Data Setting	Operation Mode
H0000	NET operation mode
H0001	External operation mode
H0002	PU operation mode

The operation mode switching method is as shown below when the Pr.79 Operation mode selection value is "0".

NET mode	H0001	External	H0002	PU operation
(CC-Link)	H0000	operation mode	H0001	mode

H0002

H0000

When Pr. 79 =2, switching is performed as shown below.

NET mode H0001 External

(CC-Link) operation mode H0000

REMARKS

When Pr. 79 is other than 0, the mode is fixed.

There are no restrictions on operation mode switching.

On normal completion of operation mode setting, the write completion signal (X23) turns on, and at the same time, 0 is set to D9150.

If the value written is other than H0000 to H0002 or write is performed during inverter operation, HFFFF is set to D9150 as soon as the write completion signal (X23) turns on, resulting in abnormal completion.

If abnormal completion occurs, the operation mode is not changed.

<Operation mode setting write program example>

The following program changes the operation mode to the NET mode.

Operation mode write setting request

Normal write

Abnormal write

Turns on operation mode setting write request pulse.

Check whether operation mode setting write completion signal turned on to judge whether write was performed normally or not.

Stores 0 (CC-Link operation mode) to D9143 and turns on operation mode setting write command. (Until completion signal turns on)
