Vacon 100 flow Applications Manual

The checklist for the commissioning a Multi-pump (multidrive) system is in 10.16.1 Multi-
pump (multidrive) commissioning checklist.
Each motor has a drive controls that applicable motor. The drives of the system
communicate with each other by Modbus RTU communication.

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. The internal PID controller
in the drive of the regulating motor controls the speed, the start and stop of the motors.
The operation of the system is specified by the selected operation mode. In the Multifollower
mode, auxiliary motors follow the speed of the regulating motor.
Pump 1 controls and pumps 2 and 3 follow the speed of pump 1, as the curves A show.
