Operation Selection Function Parameters
(1) Operation using the PLC function
The "P.RUN" LED that indicates the PLC function operation is lit when the SQ
signal is turned on. When the following setting is to be made in the sequence
program, the PU operation mode (Pr. 79 = 0, 1 or 3) must be selected.
•
Running frequency write
•
Inverter parameter rewrite
•
Inverter parameter clear or all clear
(2) Operation using CC-Link communication
CC-Link communication operation cannot be performed unless the "PU" and
"EXT" LEDs on the operation panel flicker slowly.
In either of the following two methods, light up the "L.RUN" LED.
<Method 1: Set "H0000" in device D9143 "operation mode selection write".>
• Create an operation mode setting program using GX Developer. (Refer to page 122.)
<Method 2: Set "1" in Pr. 340 "link start up mode selection".>
1)The parameter setting can be changed using the FR-PU04 (option).
2)Using GX Developer, change the setting of the inverter parameter (Pr. 340). (Refer
to page 131.)
POINT
Set "0" (factory setting) or "2" in Pr. 79 "operation mode selection".
REMARKS
The operation mode can also be set using an RS-485 communication user program. (Refer
to page 79.)
POINT
•Priority of X5 and X15 (SQ signal)
Always short X5-SD to execute (RUN) the built-in PLC of the inverter.
RUN/STOP of the built-in PLC can be controlled by turning on/off X15 via CC-
Link. To perform this control, the external input terminal X5-SD must be
shorted in advance. When the X5 terminal is off, the X15 command is
ignored.
Also note that when the built-in PLC is in a STOP status with Pr. 338
"operation command source" set for CC-Link (setting "0"), X5-SD shorted,
and X15 off, the sequence program will run as soon as Pr. 338 "operation
command source" is switched to external input (setting "1").
POINT
Switch power on again. After power is restored, the inverter is placed in the
CC-Link operation mode, the "PU" and "EXT" LEDs flicker slowly, and the
operation and start commands using CC-Link communication are made
valid. (The setting is not made valid unless power is switched on again.)
REMARKS
The Pr. 340 setting can also be made using an RS-485 communication user program.
