This chapter explains practical programs for inverter communication.
10.1
Practical Example 1
This fundamental program example monitors operations of an inverter, controls operations of the inverter and
writes parameters to the inverter.
Programs can be made simpler and the communication time can be reduced by using the IVMC instruction as
long as the PLC and inverter support the IVMC instruction.
For details on PLC versions support the IVMC instruction, refer to section 9.9.
Refer to "9.9.2 Applicable inverters" for supported inverters.
10.1.1 System configuration example
An FX PLC (ch 1) is connected to an inverter.
10.1.2 Contents of operation
As an example of operation control, an inverter can be stopped (X000), rotated forward (X001) and rotated
reverse (X002).
By changing the contents of D10
*1
, the speed can be changed.
The contents of D10
*1
can be changed from a sequence program or display unit.
