12 INVERTER COMMUNICATION INSTRUCTION
12.2 Inverter operations control(Drive)
12.2 Inverter operations control(Drive)
IVDR
This instruction writes a control value necessary for inverter operation to a CPU module using the computer link operation
function of the inverter.
■Descriptions, ranges, and data types
*1 Refer to Serial communication manual or respective inverter manual.
■Applicable devices
*1 T, ST, C cannot be used.
The control value specified in (s3) is written to the instruction code specified in (s2) of an inverter connected to the channel to
be used (n) whose station number is specified in (s1). For details, refer to Serial communication manual. (For the
instruction codes, refer to the each inverter manual.)
Three devices are occupied from the device specified in (d). Make sure that these devices are not used in other controls.
For communication errors, refer to Serial communication manual.
