Master parameter Initial value Function
Proportional gain
(Kp)
10.00
It indicates the speed of tracking the set working
pressure. A greater value indicates a higher speed
of tracking and easier oscillation. A smaller value
indicates a lower speed of tracking and slower
adjustment. The recommended setting range is
5.00
–15.00.
Integral time 2.00 The recommended setting range is 2.00
–4.00.
Differential time (Td) 1.00
It is used for lag tracking on the large-scale lag
system (such as temperature).
Sampling time (T) 0.100s It indicates the sampling period for feedback values.
PID output upper
limit
100%
It indicates the upper limit of the output of the PID
regulator.
PID output lower
limit
0.0%
It indicates the lower limit of the output of the PID
regulator. It is set based on the lower limit
frequency.
Max. output
frequency
50.00Hz
It indicates the maximum output frequency of the
VFD.
