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
conditions of the machine or installation are taken into account.
Distributed motor starters are available for PROFIBUS DP and
AS-Interface.
The starters can be installed in the vicinity of the motor or
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.
All starters are equipped throughout with standardized inter-
faces for data and power in accordance with the ECOFAST
specification (DESINA compatible):
• HanBrid for PROFIBUS DP resp. insulation displacement
method for AS-Interface
• Han Q8 for the power supply
• Han 10e for motor connection
The starters can be connected using T pieces for data and
power to prevent interruption.
