When the deviation value accumulated by
integral time, need to set an upper limit for
deviation accumulation. For example, the upper
integral limit of frequency is equal to 01-03(P.3) *

 Calibration instructions for the offset and gain of the analog feedback signal:
1. The user does not connect the feedback signal for correction, the corresponding relationship is as follows:
3-5 input analog voltage signal
3-5 input analog current signal
Correction voltage
Correction ratio
Correction current
Correction ratio
0.1V
08-18(P.223)
4mA
08-18(P.223)
5V
08-19(P.224)
20mA
08-19(P.224)
Note: 1. The default setting corresponds to a range of 0.1~5V. If it does not match the range needed, please set
08-18 (P.223) and 08-19 (P.224). Also need to set 08-00 (P. 170)at the end to achieve uniform range.
2. To use terminal 3-5 as the PID feedback source, be sure to set 02-20 (P.17) and AVI-ACI switch first, to select
the voltage/current for terminal 3-5 signal.
Example 1：Use 0~7V for feedback signal on terminal 3-5
08-18(P.223) = 0.1 / 7 * 100.0 = 1.4
08-19(P.224) = 5 / 7 * 100.0 = 71.4
After setting 08-18 (P.223) and 08-19 (P.224) according to the above calculated value, set 08-00 (P.170)=2,
then the range after calibration is 0~7V.
Example 2: Use 0~20mA for feedback signal on terminal 3-5
08-18(P.223) = 4 / 20 * 100.0 = 20.0
08-19(P.224) = 20 / 20 * 100.0 = 100.0
After setting 08-18 (P.223) and 08-19 (P.224) according to the above calculated value, set 08-00 (P.170)=2,
then the range after calibration is 0~20mA.
