CM1 range consisted of two case sizes:
Case Size A: 1.5, 2.2 & 3kW; Case Size B: 4, 5.5 & 7.5kW
all were 400V, 3 phase with built-in Class A EMC filters.

Speed adjustment is made via a potentiometer behind a cover blanking gland.
A second cover blanking gland hides a RS485 interface, where a hand-held unit could be used to set drive parameters for more complex applications.
Replaced by the CM2 in 1997.

6SE96 MicroMaster Integrated, "MMI"

MMIFor the first time, the inverter was designed to mate with almost any manufacturer's motors, a move aimed at market leadership and the highest sales volumes.

So the "MicroMaster Integrated" was conceived.
IEN Award
The European trade journal Industrial Engineering News awarded COMBIMASTER 2 the
"New Product Award 1999" for its innovative technology and high customer interest.
