12 INVERTER COMMUNICATION INSTRUCTION
12.6 Inverter multi command
12.6 Inverter multi command
IVMC
This instruction writes 2 types of settings (operation command and set frequency) to the inverter, and reads 2 types of data
(inverter status monitor, output frequency, etc.) from the inverter at the same time.
■Descriptions, ranges, and data types
*1 Refer to Serial communication manual.
■Applicable devices
*1 T, ST, C cannot be used.
This instruction executes multiple commands of an inverter connected to the channel to be used (n) whose station number is
specified in (s1). Specify the send/receive data type using (s2), the head device which stores data to be written to the inverter
using (s3), and the head device which stores values to be read from the inverter using (d1). For details, refer to Serial
communication manual.
