Mitsubishi Electronics 700 Series Parameter clear D9147, All parameter clear program example

Inverter Status Monitoring, Special Registers for Control

(5)Parameter clear (D9147)

Writing H9696 or H9966 to D9147 clears all parameters. Writing H5A5A or H55AA to D9147 clears the parameters other than the communication parameters (Refer to the Inverter instruction manual (applied)).

			cleared.

At completion of clear, the write completion signal (X27) turns on, and at the same time, 0 is set to D9150. If any value outside the setting range is written or write is performed during inverter operation, HFFFF is set to D9150 as soon as the write completion signal (X27) turns on, resulting in abnormal completion. If abnormal completion occurs, the parameters are not cleared.

REMARKS

Check the terminal function parameters and communication-related parameters in the parameter list (Refer to the Inverter instruction manual (applied)).

POINT

Setting is enabled in the PU operation mode and NET operation mode. Refer to the inverter instruction manual (applied).

<All parameter clear program example>

The following program clears all parameters.

All parameter clear request

Normal write

Abnormal write

Turns on all parameter clear request pulse.

Check whether all parameter clear signal turned on to judge whether write was performed normally or not.

Stores H9696 (all parameter clear code) to D9146 and turns on alarm definition batch clear command.

(Until completion signal turns on)
