Overview
Distributed motor starters are used for switching and protecting
loads locally. Versions with graded functional scope and with
different installation possibilities ensure that both the functional
requirements of the process and the constructional boundary
loads locally. Versions with graded functional scope and with
different installation possibilities ensure that both the functional
requirements of the process and the constructional boundary
conditions of the machine or installation are taken into account.
Distributed motor starters are available for PROFIBUS DP and
AS-Interface.

mounted onto the motor.
The following are available
• Single units for geographically distributed motors and
• Isolated solutions (ET 200X) for drives installed close together.
The functionality in the ECOFAST system ranges from direct on-
line starters, to reversing starters and soft starters through to
frequency converters (ET 200X).

Brake contacts are available as an option for the starters.
Two resp. four integrated digital contacts enable sensors to be
scanned locally.
