Communication operation and setting Parameter
6 - 486
6.23.7 Operation by PLC function (Pr. 414 to Pr. 417, Pr. 498, Pr. 506 to 515)
I/O data read, write, etc. can be performed by accessing the inverter in the predetermined
method using special relays, special registers, etc.
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.
Refer to the FR-A700 PLC function programming manual for details of the PLC function.

PLC function is valid
(Inverter reset is necessary to make this
setting valid.)

0
The inverter start signal is made valid
regardless of the sequence program execu-
tion key.
1
The inverter start signal is made valid only
when the sequence program execution key
is set to RUN.
When the sequence program execution key
is in the STOP position, the inverter does
not start if the inverter start signal STF or
STR is turned on. (If the key is switched
from RUN to STOP during inverter opera-
tion, the inverter is decelerated to a stop.)

0 to
65535
Inverter parameters Pr. 506 to Pr. 515 can
be used as user parameters.
Since this parameter area and the devices
used with the PLC function, D110 to D119,
are accessible to each other, the values set
in Pr. 506 to Pr. 515 can be used in a
sequence program.
The result of operation performed in the
sequence program can also be monitored
using Pr. 506 to Pr. 515.
