Set frequency RAM D9144 | Mitsubishi Electronics FR-A700 specification

Inverter Status Monitoring, Special Registers for Control

(2)Set frequency (RAM) (D9144)

The D9144 data is written to the RAM as a set frequency. The unit is 0.01Hz. (For example, 6000 indicates 60.00Hz.)

When the speed is set, the speed is either 1r/min or 0.1r/min.

The range where the frequency can be set is 0 to 12000 (0 to 120.00Hz).

When the frequency setting is written normally, the write completion signal (X24) turns on, and at the same time, 0 is set to D9150.

If any value outside the range is written, HFFFF is set to D9150 as soon as the write completion signal (X24) turns on, resulting in abnormal completion. If abnormal completion occurs, the set frequency is not changed.

POINT

•The frequency can be set in the PU operation mode and NET operation mode. Refer to the inverter instruction manual (applied).

<Set frequency write (RAM) program example>

The following program changes the set frequency (RAM) to 30Hz.

Set frequency write (RAM) setting request

Normal write

Abnormal write

Turns on set frequency

write (RAM) command pulse.

Check whether set frequency write (RAM) completion signal turned on to judge whether write was performed normally or not.

Stores 3000 (30Hz) into D9144, and turns on set frequency write (RAM) command.

(Until completion signal turns on)
