started first.
According to the principle of start first–stop first control, in order to ensure that every pump
can have the chance to run to prevent some pumps rusted as a result of no use for long , such as
the need to ensure that each operation of the pump can receive equal time, set timing shift
alternation time.
Pump alternation order : E12 = 0x 0001
Starting State :
No. 1 pump frequency;
No. 2 pump frequency conversion;
No. 3 pump stops ;
Rotation :
No. 1 pump stops;
No. 2 pump frequency;
No. 3 pump frequency conversion ;
After the second rotation :
No.1pump frequency conversion;
No.2pump stops;
No.3pump power frequency.
E09
Electromagnetic switch
action delay

s
0.500
Y
Electromagnetic switch action delay time when set up a pump (drive motor) to switch from
variable frequency to industry frequency,or from industry frequency to variable frequency.
This is to avoid inverter output frequency meet with the AC power supply and occur short
circuit caused because electromagnetic switch action too slow.
E10
Pumps shift judging time
0~9999
s

Y
Set when output frequency converter arrives to upper frequency, until the judgment time of
Increasing pumps (driving motor); or when output frequency converter arrives to lower
frequency, until
The judgment time reducing pumps ( driving motor). Set the time long or short according to
the speed of
Pressure change, without oscillating range, the shorter the better.
Drives add or subtract pump control with E12 Water Supply Configuration
Add pump order No. 1 pump → No. 2 pump → No. 3 pump → No. 4 pump.
Reduce pump order No. 4 pump → No. 1 pump → No. 2 pump → No. 3 pump.
If the current : No. 1 pump frequency, No. 2 pump frequency, No. 3 pump convert frequency
after reduce pump: No. 1 pump frequency, No. 2 pump convert frequency,
after add pump: 1 pump frequency, No. 2 pump frequency, No. 4 pump convert frequency
after reduce pump :No. 1 pump frequency, No. 2 pump convert frequency,
after reduce pump: No. 1 pump frequency,
after add pump: No. 1 pump frequency, No. 3 pump convert frequency
after add pump: No. 3 pump frequency No. 4 pump convert frequency
