1.7 Inverter Status Monitoring, Special Registers for Control

You can assign the data for grasping and changing the inverter's operation status to D9133 - D9147 and read/write them from the user sequence. (Refer to page 14 for the list.)

1.7.1Data that can be read at all times

The following data can always be read. They are automatically refreshed every time the END instruction is executed.

(1) Operation monitor

The following data devices are always read-enabled (write-disabled) to allow you to monitor the output frequency, output current and output voltage of the inverter. Note the setting units.

Device	Name	Setting	Data Example		Data Access Enable
No.		Unit			Condition
D9133	Output frequency	0.01Hz	Device data 6000	→ 60.00Hz
	monitor
D9134	Output current	0.01A	Device data 200 → 2.00A		Always
	monitor
D9135	Output voltage	0.1V	Device data 1000	→ 100.0V
	monitor

CAUTION

The frequency can be set in increments of 0.01Hz but actual operation is performed in increments of 0.1Hz.
