FR200 Series Vector control inverter
- 120 -
When the offset between setting and feedback is less than the set value of F13.15, PID
adjustment is determined by Kp1, Ti1 and Td1. When the offset between setting and feedback is
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:1.0%
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:00
～
11
Default:00
Unit's digit (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 digit (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.
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
Detection value of PID
feedback loss
Range:0.0%
～
100.0%
Default:0.0%
F13.25
Detection time of PID
feedback loss
Range:0.0
～
30.0s
Default:1.0s
When offset between feedback and setting of PID is less than set value of F13.24 and the lasting
time attains the set time of F13.25, the drive reports fault “Err19". If F13.24 is set to 0.0, feedback loss
detection is disabled.
F13.26
PID operation at stop
Range:0
～
1
Default:0
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.
Group F14 Swing Frequency, Fixed Length, Count and Wakeup
The swing frequency function is applied to the textile and chemical fiber fields and the applications
where traversing and winding functions are required.
The swing frequency function indicates that the output frequency of the AC drive swings up and
down with the set frequency as the center. The trace of running frequency at the time axis is shown in
the following figure. The swing amplitude is set in F14.00 and F14.01. When F14.01 is set to 0, the
swing amplitude is 0 and the swing frequency does not take effect.
