IVRD
This instruction reads a parameter of an inverter to the CPU module.
Setting data
■
Descriptions, ranges, and data types
*1 Refer to
MELSEC iQ-F FX5 User's Manual (Serial Communication) or respective inverter manual.
■
Applicable devices
*1 T, ST, C cannot be used.
Processing details
The value of the parameter (s2) is read from an inverter connected to the communication channel (n) whose station number is
(s1), and output to (d1). For details, refer to
MELSEC iQ-F FX5 User's Manual (Serial Communication). (For the
parameter numbers, refer to the each inverter manual.)
Precautions
Three devices are occupied from the device specified in (d2). Make sure that these devices are not used in other controls.
