Note: When the Fixed Speed Auto is activated, the sleep and lead-lag functions are disabled. This configuration is only active

in Auto Mode.

The L4-01 parameter of the last drive controls the previous drive and activates the Auto Mode (when the frequency level drops below

L4-01).

◆ MEMOBUS / Modbus Communication <0034>

The current iQpump software only allows the drive to be a slave on a MEMOBUS / Modbus Network which means that an external

device such as a computer or PLC needs to be connected to the network and issue commands to the drives. Having a drive act as a

MEMOBUS / Modbus Master eliminates the need for an external master and introduces better drive control since it can be configured for

either a general or specific application feature.
