deceleration
0~2: The number of opening pumps
in the constant pressure water
supply control
3: close the pump control
The factory default is 3,so if use
constant pressure water supply,
please set D12 to be 0~2.
D06 PID
Feedback bias
value
Deviation adjustment to frequency
order control by PID.
Unit:1%
D07 Limit of PID
integral value
Set the up limits value of frequency
output controlled by I.
Unit:1%
D08 Feedback
filter time
Set the one time delay data of
frequency order controlled by PID.
D09 Feedback
loss detection
0:Detection is disabled
1:Detection is enabled
D10 Feedback
loss detection
level
Feedback lost test standard (PID),
set losing grade of PID feedback
with unit of 1%.
D11 PID
Feedback
loss time
Delayed feedback lost time (PID),
set testing PID feedback lost time.
D13 Rotation
time
When the two auxiliary pumps only
one work, in order to average the
time of working for every pump, the
working time for one pump is D13
and then change to work for another
one.
D14 Interlock
time
When the two auxiliary pumps only
one work, in order to average the
time of working for every pump, the
working time for one pump is D13
and then change to work for another
one. This time is the middle waiting
time.
D15 High-speed
working
When the water consumption is
increasing ,the AC drive is working
on the max frequency, when
it reach the setting time D15, the
corresponding multi-functional
contact action
D16 Low-speed
working
When the water consumption is
reducing, the AC drive is working
on the min frequency, when it reach
the setting time D16, the correspon-
ding multi-functional contact action.
D17 Stopping
Standard
When the water consumption is
reducing, all of the auxiliary pumps
have turned off, the main pump are
working on the min frequency, when
meet the following conditions:
1:(setting frequency/max frequency)*
D17<PID feedback value
2:The time exceed D18
The AC drive stops output, and be
in sleep mode.

D19 Wake-up
standard
The AC drive is in sleep mode.
When the water consumption is
increasing, the pressure of the
pump will reduce accordingly. When
meet the following conditions:
1: (setting frequency/max frequency)
*D19>PID feedback value
2: The time exceed D20
The AV drive begins outputting, the
pump starts working.
