Fixed modes of inverter pump:
In the fixed modes of inverter pump, RY1 is permanently used and RY2~RY8 is arbitrarily selected to be
used.
Inverter decelerates/ accelerates to lower/ upper limit frequency when user increases/ decreases pumps
and function of PID is temporarily disabled. When the inverter reaches lower/ upper limit frequency,
function of PID restores and the inverter output is determined by the feedback.
Cycle modes of inverter pump:
In the cycle modes of inverter pump, RY2 and RY1 are always used. The rest (RY3~RY8) is a group of
two, RY3/RY4, RY5/RY6, and RY7/RY8. If any one of the group is set to be disabled, this group is
disabled.
The inverter output disconnects when user increases pumps. When a motor originally drived by the
inverter is switched by commercial AC power supply, it requires the switching time of magnetic contactor
(24-05) to allow the AC power supply input. Then the inverter output drives the next motor, which is
determined by the feedback.
Switch off the motor of the first on when user decreases pumps to make the pump (motor) be the equal
using frequency.
Cycle modes of inverter pump in the control board:
In the cycle modes of inverter pump, RY1 is permanently used and RY2~RY3 is arbitrarily selected to be
used. 24-01 can only set 0xxx (Relay 4 can not be set.) and 24-02 can only set 0000 (Relay 5-8 can not be
set.) so this parameter will be hidden.
24- 03 Duration of Upper Limit Frequency
Range
【
1.0 ~ 600.0
】
Sec
Set the inverter output frequency controlled by PID reaches the upper limit frequency (the proportion
setting by parameter 00-12) via parameter 24-03. 1 to 8 pump card controls the time required for
increasing pumps.
The setting value of duration of upper limit frequency (24-03) is determined by the changing time speed of
system pressure. The setting value of 24-03 is the fewer the better in the range without producing
oscillation of system pressure.
24- 04
Duration of Lower Limit Frequency
Range
【
1.0 ~ 600.0
】
Sec
Set the inverter output frequency controlled by PID reaches the lower limit frequency (the proportion
setting by parameter 00-13) via parameter 24-04. 1 to 8 pump card controls the time required for
decreasing pumps.
