Description: Enables the multi-pump control function.
0: Multi-pump control inhibited
1: Multi-pump control enabled
Value: 0: disable
1: enable
Dependency: The "Multi-pump control" function is only available for induction motors.
The "Multi-pump control" function is not supported on G120X inverter variants of power rating 30kW or above.
Note
when P29520=0, P29521 cant set to a !0 value.
when P29520 value change from 1 to 0, P29521 value will change to 0 automatically

Description: Selects the number of motors that will be used as multi-pump control.
Value: 0: NONE
1: M1=1X
2: M1=1X,M2=1X
3: M1=1X,M2=1X,M3=1X
4: M1=1X,M2=1X,M3=1X,M4=1X
Note
1X means motor power that configured in P307.
Currently multi-pump control only support that all motors should have the same power.

Description: Parameter for selecting the control mode for swtiching-in and switching-out motors
Value: 0: Fixed sequence
1: Absolute operating hours
Note
For p29522=0:
Motor selection for switching-in/switching-out follows a fixed sequence and is dependent on the multi-pump control
configuratin(p29521).
For p29522=1:
Motor selection for switching-in/switching-out is derived from the operating hours counter p29530.When switching-in,
the motor with the least operating hours is connected.When switching-out,the motor with the most operating hours is
disconnected.
