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 )
