Detailed instruction of parameters
0.0~6000.0h
Automatic circulation among idle power frequency
motors, no circulation in the stage of adding or
reducing motors or hibernation, no circulation all
the time when setting to 0
0.0~6000.0h
Automatic circulation among idle variable
frequency motors, no circulation in the stage of
adding or reducing motors or hibernation, no
circulation all the time when setting to 0
P00.05~P00.03
When the running frequency is larger than the
value, there will be no circulation for variable
frequency motors to protect water supply from big
changes of water pressure.
0.2~100.0s
Time from sending contactor switching-on
command to switching on actually, send the
inverter start command after delaying the time
0.2~100.0s
Time from sending contactor switching-off
command to switching off actually, connect to
power frequency after delaying the time
0.00~P00.03
