Prior to Sequence Program Creation
4.2.3
Sequence program execution key
The sequence program execution key (STOP/RUN) of the PLC is switched by turning
off/on the SQ signal.
POINT
SQ-SD must be shorted to execute the built-in PLC function. (Built-in
sequence signal: X5 ON)
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. 507 "inverter operation lock mode setting".
(Refer to page 40.)
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 143)
REMARKS
•Refer to page 8 for the SQ terminal specifications.
•The validity limit of the SQ terminal can be controlled using Pr. 507 "inverter operation lock
mode setting". (Refer to page 138.)
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.
