Func. Name Description
F_015
Control Mode
Selection
(Pump Parallel)
=0: Disable the functions related to pump.
=1: Single pump application.
*Constant pressure is controlled by single pump.
=2: Multi-pump applications; E-mode (Equal-mode).
*Pumps run at identical speed to maintain the pressure in
constant.
*Recommend to select this mode for 2 pump applications to
increase the efficiency and save the energy.
=3: Multi-pump applications; F-mode (Full-mode).
*Only one pump auto-adjusts the speed, and other pumps
run at full speed when the multi-pump system outputs the
constant pressure.
*Recommend to select this mode for more than 2-pump
operations to increase the efficiency and save the energy.
=4: Multi-pump applications; M-mode (Manual-mode).
*Pump ON/OFF is controlled by multi-function input
terminals (X1, X2, X3).
*F_052, F_053, F_054 must set to
―0‖.
*Drive will start/stop in sequence when any terminal is
activated.
*Recommend to select this mode when installing or trial
running the pump.
=5: Multi-pump applications; S-modet
*Lead pump which have an automatic speed control,
auxiliary pump1 or pump 2 will follow setting condition to run.
AC power start operating to maintain constant pressure.
*Start condition of sequential operation:
Lead Pump

Auxiliary Pump1

Auxiliary Pump2
(1) When lead pump run at full speed, but PV value < F_022
(Start detection level), the multi- output terminal will detect
immediately and start the auxiliary pump 1 (AC power); And
so on, auxiliary pump 2 will start in sequence.
(2) When lead pump run at full speed, and operating time >
F_021(Start detection time), the muti-output terminal may
detect immediately and start auxiliary pump 1 (AC power);
And so on, auxiliary pump2 will start in sequence.
*Stop sequential operation:
Auxiliary Pump2

Auxiliary Pump1

Lead Pump
*Auxiliary pump stop condition:
(1) When PV value > F_022(Start detection level), the
muti-output terminal may detect immediately and stop
auxiliary pump 2(AC power stop), and so on, auxiliary
pump 1 will stop in sequence; When operating frequency of
lead pump < F_133( Drive standby level), lead pump will
decelerate and stop.
