【
Feedback Signal Disconnection Detection
】
F1709 Feedback signal disconnection detection time
The function to set the disconnection detection of feedback signal and the detection time.
● Detect the relationship between PID control command value and feedback value, when there is an abnormal
situation, it will be judged as disconnection, warning or alarm for shutdown.
· F1709=0: only warning (the inverter will continue to run).
During disconnection detection, even when it is judged as disconnection, the inverter will continue to run, a
warning of
“ ”
will be displayed.
If it stops during warning display, the inverter will also stop the free run.
· F1709=0.01
-
119.99: set the detection time of disconnection judgment. (Initialization=5s)
During disconnection detection, when it is judged as disconnection,
“ ”
will be displayed and an
alarm for shutdown will be output.
When the system response speed is very slow and a false detection may happen, please prolong the detection
time.
· F1709=120: no disconnection detection.
No action of disconnection detection, warning or alarm for shutdown.

PID Various Variables Output
】
F1501 Internal analog output function 1
F1504 Internal analog output function 2
The function to output (0

10V) the various variables in PID control from the analog output AOUT1/AOUT2.
● F1501 will output signal through AOUT1, F1504 will output signal through AOUT2. Refer to the following table for
output variable and setting.
● The output format of each PID variable is 120Hz/10V.
● Please adjust the coefficient and offset of output signal according to F1502 (AOUT1)/F1505 (AOUT2) and F1503
(AOUT1)/F1506 (AOUT2).

Note: The variable of PID control will be output with an absolute value. When it is negative, it will be positive during
output.
Besides analog output, the internal variables in PID control can also be displayed on operation panel timely.
● The follows are function code and variable as well as the setting value displayed on the operation panel.
