Parameter Groups
‑272‑
0.00 Hz to value of F0‑10
Description
When the frequency source is only the PID, the PID cut‑off frequency in reverse
direction is the minimum value of the current PID output. When the frequency
source is main frequency + PID, FA‑08 acts on the main frequency + PID and
outputs the minimum frequency value after "main frequency + PID" operation.
FA-09
PID deviation limit
Address:
0xFA09
Min.:
0
Unit:
%
Max.: 100 Data type: UInt16
Default:
0
Change: In real time
Value Range:
0.0% to 100.0%
Description
When the deviation is within the PID deviation limit, no adjustment is required.
This parameter helps balance the accuracy and stability of the system output.
FA-10
PID differential limit
Address:
0xFA0A
Min.:
0
Unit:
%
Max.: 100 Data type: UInt16
Default:
0.1
Change: In real time
Value Range:
0.00% to 100.00%
Description
It is used to set the PID differential output range. In PID control, the differential
operation may easily cause system oscillation. Therefore, the PID differential
regulation is restricted to a small range.
FA-11
PID reference change time
Address:
0xFA0B
Min.:
0
Unit:
s
Max.: 650 Data type: UInt16
Default:
0
Change: In real time
Value Range:
0.00s to 650.00s
Description
This parameter defines the time required for the PID reference to change from
0.0% to 100.0%.
