5.1 Operation
This section describes the program used for operation stop (X0), forward rotation (X1), and reverse rotation (X2) to
control operations of the station number 0 (first inverter).
The frequency setting can be changed by changing the value set in D11.

Inverter operation control
The following example program use the IVMC instruction.
5
The IVMC instruction simplifies the programs and reduces communication time.

The programmable
controller starts
communicating with
the inverters when the
precondition turns ON.
