MULTIDRIVE CONFIGURATION
The Multidrive modes (Multimaster and Multifollower) control a system that has the
maximum 8 variable speed pumps. Each pump is controlled by a drive. The internal PID
controller of the drive controls all pumps. The drives use a communication bus (Modbus
RTU) for communication.
The figure below shows the Multidrive configuration principle. See also the general electric
diagram of a Multi-pump system in Fig. 18 Electric wiring diagramme of the Multi-pump
(multidrive) system, example 1A.
