Windmill application

Phase1 - Use of CANopen DIV and PSC2 digital Controller

Phase2 - Use of Profibus Motion Control Valve (MCV) with local CANopenloop closure

Moog DIV Application:

Analog wiring into rotating equipment is very difficultLower system cost with higher reliability using

fieldbus technology the new concept requires

three individual axis instead of one with

mechanical coupling ( need for local intelligence,

synchronized axis )
