Outline of PLC function
• To enable the PLC function, set a value other than "0" in
Pr.414 PLC function operation selection
. When "2 or 12" is set
in
Pr.414
, the Sequence startup (SQ) signal from the external input terminal is valid regardless of the setting of the
Pr.338
Communication operation command source
. (The
Pr.414
setting change becomes valid after inverter reset.)
• Switch the execution key (RUN/STOP) of the sequence program by turning the SQ signal ON/OFF. The sequence program
can be executed by turning the SQ signal ON. To input the SQ signal, set "50" in any of
Pr.178 to Pr.189 (Input terminal
function selection)
to assign the function to a terminal.
• When "1" is set in
Pr.415 Inverter operation lock mode setting
, the inverter can be operated only when the sequence
program is running. By changing the PLC program status from RUN to STOP during inverter operation, the motor
decelerates to stop.
To stop the inverter operation at the STOP status of the PLC program while performing auto operation using SD1148 (or
SM1200 to 1211) of the PLC program, set
Pr.415
= "1".
• For reading or writing sequence programs, use FR Configurator2 on the personal computer connected to the inverter via
RS-485 communication or USB. (When
Pr.414
≠
"0", sequence programs can be read from or written to FR Configurator2.)
User parameter (data register (D)) auto storage function selection
• Setting
Pr.675
= "1" enables the auto storage function for user parameters.
• The user parameter auto storage function is used to store the setting of
Pr.1195 PLC function user parameters 46
(D251)
to
Pr.1199 PLC function user parameters 50
(D255) automatically in EEPROM at power OFF or inverter reset.
• The auto storage function is disabled while the inverter performs any of the following.
Measurement of the main circuit capacitor's life, offline auto tuning, or measurement of load characteristics
NOTE
• The auto storage function may fail if the EEPROM is accessed by other functions at the same time at power OFF. To ensure
the auto storage, provide a power source for the control circuit separately from that of the main circuit.
User parameter reading from EEPROM
• User parameters (
Pr.1150 to Pr.1199
) are read from RAM or EEPROM according to the settings in
Pr.342 Communication
EEPROM write selection
and
Pr.414 PLC function operation selection
. When
Pr.414
= "11 or 12", RAM data is read
regardless of the
Pr.342
setting.
NOTE
• For the details of the PLC function, refer to the PLC Function Programming Manual and the Instruction Manual of FR
Configurator2.
