1.5.3 Sequence program execution key
The sequence program execution key (STOP/RUN) of the PLC is switched by turning
off/on the SQ signal.
Open (STOP) the SQ signal-SD terminals when writing a sequence program, for
example.
When executing the sequence program, short (RUN) the SQ signal-SD terminals.
Remote run/stop of the built-in PLC function can be executed in any of the following
methods:
• Setting using the built-in PLC function parameter (contact)
• Using GX Developer
• Via CC-Link communication (refer to page 49)
POINT
•For the terminal used for SQ signal input, set "50" in any of Pr.178 to Pr. 189 to
assign the function.
•SQ-SD must be shorted to execute the built-in PLC function.
REMARKS
•The validity limit of the SQ signal can be controlled using Pr.415 Inverter operation lock mode
setting. (Refer to page 43.)
CAUTION
The outputs (Y) are cleared by turning the SQ signal off (STOP) after sequence program
execution (SQ signal on).
The other devices retain the device data prior to STOP. When you want to clear the
remaining device data, power off or reset (short RES-SD for 0.1s, then open) the
inverter.
CAUTION
If the SQ signal is not turned on, the start signal of the inverter is designed to
become valid by the factory setting of
Pr.415 Inverter operation lock mode setting .
