MULTI-PUMP (SINGLE DRIVE) APPLICATION
You can use Multi-pump (single drive) application in applications, where 1 drive controls a
system that has the maximum of 8 parallel motors, for example, pumps, fans or
compressors. By default, Multi-pump (single drive) application is configured for 3 parallel
motors.
The drive is connected to 1 of the motors, which becomes the regulating motor. The internal
PID controller of the drive controls the speed of the regulating motor and gives control
signals by relay outputs to start or stop the auxiliary motors. External contactors (switch) set
the auxiliary motors to the mains.
You can control a process variable, the pressure for example, by the control of the speed of
the regulating motor and by the number of motors that operate.
See the descriptions of the parameters in 10 Parameter descriptions.
