9.6 Inverter Parameter Reading (PLC←Inverter) [FNC272 / IVRD]
This instruction reads a parameter of an inverter to the PLC.
9.6.1 Function and operation
When a parameter number of an inverter is specified in IVRD (FNC272) instruction, the value of the
parameter is read to .
1. Applicable devices
2. Program example
9.6.2 Inverter instruction codes
Refer to related data shown later.
9.6.3 Program example of "second parameter specification code"
→ For second parameter specification code, refer to Section 9.9.
In the program example shown below, the parameters (frequency: 201, time: 1201, motor rotation direction:
2201) are read from the A500 inverter whose station number is 6.
Read devices: D100 = Motor rotation direction, D101 = Frequency, D102 = Time
