5. EXAMPLE PROGRAMS
Operation
1
This program is used for operation stop (X10), forward rotation (X11), and reverse rotation (X12) to control operations of the inverter.
The frequency setting can be changed by changing a value set in D31.

Inverter station number: 1
Inverter status information read to D40 using the IVMC instruction
D40 K4M300 The information is stored to M300 to M315 using the MOV
instruction.

Transferred to D60.
When the operation speed is
set to D31, it is stored in
(s3)+1 of the IVMC instruction
as the data to be written to
an inverter.
Information on the forward and reverse
rotation commands is transferred to
D30 using the MOV instruction.
The information in D30 is stored in (s3)
of the IVMC instruction as the data to
be written to an inverter.
