Compatible inverter models
1.1 Compatible inverter models
This Instruction Manual provides information about the PLC function, which is
available with the upgraded FR-F700-NA/EC inverters. To find out whether an FR-
F700-NA/EC is equipped with the PLC function, check the Instruction Manual of the
inverter.
1.2 Block diagram
How I/O data is 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.
* Setting "9999" in Pr.178 to Pr.189 (input terminal function assignment) and Pr.190 to Pr.196
(output terminal function selection) changes these terminals to general-purpose I/O terminals.
Refer to the inverter manual for details of Pr. 178 to Pr.189 and Pr.190 to Pr.196.
