The regulation relationship between C1.05,C1.07 and
reference is shown in Fig.6-42.When the analog input
6V,if C1.05
＝
0% and C1.07
＝
100%
，
then adjusted value
is 60%.If C1.05
＝
25% and C1.07
＝
100%
，
then the
adjusted value is 46.6%.

If the analog type is current input,because the
currentinput range is 4

20mA,then the range of X axis
is 50%

The adjusted value can be observed in d0.24.
The regulation relationship between C1.06,C1.08 and
feedback is similar to reference regulation.Its adjusted
value can be observed in d0.25.

The bigger the proportional gain of KP, the faster the
response, but oscillation may easily occur.
If only proportional gain KP is used in regulation, the
error cannot be eliminated completely. To eliminate the
error, please use the integral gain Ki to form a PI control
system. The bigger the Ki, the faster the response, but
oscillation may easily occur if Ki is too big.
The sampling cycle T refers to the sampling cycle of
feedback value. The PI regulator calculates once in each
sampling cycle. The bigger the sampling cycle the
slower the response.
C1.13 Output filter
0.01

This parameter defines the filter time of the close-loop
output (Frequency or torque).The bigger the output
filter,the slower the response.
C1.14 Error limit
0.0
～
20%
【
2.0%
】
This parameter defines the max. deviation of the output
from the reference, as shown in Fig. 6-43. Close-loop
regulator stops operation when the feedback value is
within this range.Setting this parameter correctly is
