F5.15误差限制范围Set up the integral regulation function and close-loop
frequency presetting function (F5.17~F5.19);
Adjust the close-loop filtering time, sampling cycle, error
limit and gain(F5.12~F5.15).
F5.00 Close-loop control function Range:0. 1【0】
0: disabled
1: enabled
F5.01 Reference selector Range:0. 1. 2【1】
0: digital input
Take the value of F5.05 (when the setting is analog
close-loop, F5.02=0~5);
Take the value of F5.06 (when the setting is pulse
close-loop, F5.02=6).
1: VCI analog voltage input(0~10V)
2: CCI analog input
Chapter 5 Parameter Introductions 57
EV2000 Series Universal Variable Speed Drive User Manual
Analog input range:0~10V(Jumper CN10 is placed at
side V), or 0~20mA(Jumper CN10 is placed at side I).
Note:
Use pulse feedback to control the speed. If the reference is
analog signal, then 0~10V (4~20mA) reference corresponds
to synchronous speed n0 (n0=120fmax/P).
F5.02 Feedback selector Range:0~6【1】
0: VCI 0~10V analog voltage input
1: CCI analog input
2: VCI+CCI
3: VCI-CCI
4: Min {VCI,CCI}
5: Max {VCI,CCI}
Settings of jumper CCI are the same with the above.
When current input is selected, the signal will be
converted into voltage signal by the formula:
Voltage value = current value (mA)/2;
6: pulse input
Both single-phase PG feedback and dual-phase PG
feedback can be used. Refer to the definitions of
multi-function input terminal X7 and X8 (functions of
F7.06~F7.07).
F5.03 Reference filter Range:0.01~50.00s【0.50s】
F5.04 Feedback filter Range:0.01~50.00s【0.50s】
Both the reference signal and feedback signal carry
noise. These signals can be filtered by setting the time
constant of filter (F5.03 and F5.04). The bigger the time
constant, the better the immunity capability, but the
response becomes slow. The smaller the time constant,
the faster the response, but the immunity capability
becomes weak.
F5.05 Digital setting of
reference Range:0.00~10.00V【0.00】
When analog feedback is used (F5.02=0~5), this
function can realize digital setting of reference via panel
or serial port.
F5.06 Close-loop speed
reference Range:0~39000rpm【0 rpm】
If PG pulse feedback is used (F5.02=6), the speed
reference can be set by panel or serial port
F5.07 Number of pulses per
revolution of PG Range:1~9999【1024】
The setting of F5.07 is determined by the parameters of
PG.
F5.08 Min reference Range:0.0%~ F5.10

F5.09 Feedback value

F5.08~F5.11 define the relationship between the
close-loop reference and feedback value. The setting is
the ratio (percentage value) of input and feedback value
to reference (10V or 20mA).

F5.12 Proportional gain KP Range:0.000~9.999【0.050】
F5.13 Integral gain Ki Range:0.000~9.999【0050】
F5.14 Sampling cycle T Range:0.01~50.00s【0.50s】
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.
