1.1 Function Block Diagram

How I/O data are transferred to/from the inverter by the built-in PLC function is explained using function blocks.

(1)I/O data read, write, etc. can be performed by accessing the inverter in the predetermined method using special relays, special registers, etc.

(2)Operation, parameter read/write, etc. can be performed in accordance with the created sequence programs (built in the inverter) using input data from the control input terminals.

With the output signals, output data can be output to outside the inverter from the control output terminals as not only the inverter's status signals but also pilot lamp on/off, interlock and other control signals set freely by the user.
