1.1 Compatible inverter models
This Instruction Manual provides information about the PLC
available with the upgraded FR-F700-NA/EC inverters. To find F700-NA/EC is equipped with the PLC function, check the Instruinverter.

predetermined method using special relays, special registers(2) Operation, parameter read/write, etc. can be performed in
created sequence programs (built in the inverter) using input input terminals.With the output signals, output data can be output to outside control output terminals as not only the inverter's status signaon/off, interlock and other control signals set freely by the use

CAUTION
A sequence program cannot be written with its stepsthe sequence program does not run. (The program range is initialized.)
Do not read the built-in PLC function parameters anwithout writing them to the inverter once using GX inverter does not have normal data, always write theparameters and sequence program once.
Since the built-in PLC function parameters and sewritten to the flash ROM, there are restrictions on the n(Approximately 100,000 times)

until a sequence program is executed.The built-in PLC function processings are roughly classified intotypes.(1) Initial processing
Pre-processing for executing sequence operation. This proonly once when power is switched on or a reset is performed(a) The inputs/outputs are reset and initialized.(b) The data memories are initialized (the bit devices are tur
devices are cleared to 0).(c) Self-diagnostic checks are made on the built-in PLC
setting, operation circuit, etc.
(2) Sequence program operation processingThe sequence program written to the built-in PLC function is eto an END instruction.
(3) END processing
Post-processing for terminating one sequence program operareturn the sequence program execution to step 0.(a) Self-diagnostic checks are performed.(b) The present values of the timers are updated and their
on/off, and the present values of the counters are updateare turned on.

The built-in PLC function parameters can be confirmed from to the GX Developer Operating Manual.)

A RUN status indicates that a sequence program is repeating of step 0 to END (FEND) instruction while the SQ signal is ONWhen entering the RUN status, the function outputs the output saccording to the "STOP to RUN-time output mode setting" (refe
(2) Operation processing in STOP statusA STOP status indicates that a sequence program is stoppinthe SQ signal is OFF or after remote STOP is commanded. (When entering the STOP status, the function saves the outpuall outputs. The contents of the data memories other than maintained.
