Opcrly Relay Option Module - GE AF-650 GP Design Manual

Set-up example
In this example a Permanent Magnet (PM) Motor is used with resolver as speed feedback. A PM motor must usually operate in flux mode.
Wiring:
The max cable length is 150 m when a twisted pair type of cable is used.
NB!
Resolver cables must be screened and separated from the motor cables.
NB!
The screen of the resolver cable must be correctly connected to the de-coupling plate and connected to chassis (earth) on the motor side.
NB!
Always use screened motor cables and brake chopper cables.
