Connection Example Using One Master and Three Basic Drives:
8.4.3.2 Addressing
When using the cascade serial/synchron mode in a multi-pump-application (where more than drive is used),
each drive must be addressed correctly.
Master drive – The address of the Master drive is set using the Hydrovar software. Dip switches are used to
program the Basic drives to a specic address. On all Master drives the dip switches must be set to address 1
(default setting, see below).
Basic Drive – When using a Basic drive in a Multi-pump-system the dip switches must be set to the appropri-
ate address for each drive in the system. The addresses for the Basic drives start after the last address of the
nal Master drive in the system. The S1 switchbank is located on the lower board behind the control panel.
(See pictures below for locations.)
Example:
Multi-pump-system with 3 Master and 4 Basic drives
• Set address 1-3 for the Master Inverters via appropriate software parameters (See submenu CONF
INVERTER [0100] or submenu RS485-INTERFACE [1200])
• Address 4-7 for the Basic Inverters via dip-switches
The pre-selected address also denes the initial pump sequence.
