bigger than the set value of F13.15, PID adjustment is determined by Kp2, Ti2 and Td2 set at F13.11
to F13.13.
2: Switched by terminal
When digital input terminal "PID parameters switch" is OFF, it is determined by Kp1, Ti1 and Td1.
When "PID parameters switch" is ON, it is determined by Kp2, Ti2 and Td2
F13.17
PID offset limit
Range:0.0
～
100.0%
Default:0.0%
If the offset between PID feedback and setting is more than this set value, PID regulator will
implement regulation. If the offset between PID feedback and setting is less than this set value, PID
will stop the regulation and the PID controller output will be kept unchanged. This function can improve
the stability of PID performance.
F13.18
PID integral property
Range:000
～
111
Default:000
Unit's place: Whether to stop integral operation when the output reaches the limit
0: Continue integral operation
1: Stop integral operation
If "Stop integral operation" is selected, the PID integral operation stops, which may help to reduce
the PID, overshoot.
Ten's place: Integral separated
0: Invalid
1: Valid
If it is set to valid, the PID integral operation stops when the DI allocated with function 25 "PID
integral pause" is ON In this case, only proportional and differential operations take effect.
If it is set to invalid, integral separated remains invalid no matter whether the DI allocated with
function 25 "PID integral pause" is ON or not.
Thousand’s place: Integral attributes
0: Incremental mode
1: Position mode
F13.19
PID differential limit
Range:0.0
～
100.0%
Default:0.5%
Set differential output limit of PID control.
F13.20
PID initial value
Range:0.0
～
100.0%
Default:0.0%
F13.21
Holding time of PID initial
value
Range:0.0
～
6000.0s
Default:0.0s
PID does not make adjustment when the drive starts its running, but outputs the value set by
F13.20 and maintains the holding time set by F13.21, then starts PID adjustment. When F13.21 is set
to 0.0, PID initial value is disabled. This function makes PID adjustment get into stable status fast.
F13.22
PID output frequency
upper limit
Range: PID output frequency
lower limit
～
100.0%
Default:100.0%
F13.23
PID output frequency
lower limit
Range:–100.0%
～
PID output
frequency upper limit
Default:-100.0%
This function is used to limit PID output frequency.100.0% corresponds to maximum frequency.
F13.24
Low value of PID feedback
loss
Range:0.0%
～
100.0%
Default:0.0%
F13.25
Detection time for low value
of PID feedback loss
Range:0.0
～
30.0s
Default:1.0s
F13.28
High value of PID feedback
loss
Range:0.0%
～
100.0%
Default:100.0%
F13.29
Detection time for high value
of PID feedback loss
Range:0.0
～
30.0s
Default:1.0s
When the PID feedback value is not in the range of F13.24 and F13.28, and lasting time attains
the set of F13.25/F13.28, then inverter will report Err19(PID feedback loss).
F13.26
PID operation at stop
Range:00000
～
11111
Default:000
Unit’s place
: operation selection when power off
0: No PID operation at stop
1: PID operation at stop
It is used to select whether to continue PID operation in the state of stop. Generally, the PID
operation stops when the AC drives stops.
Ten’s place
: PID output is limited by output frequency
0: No limit
