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.
NOTE
Resolver cables must be screened and separated from the
motor cables.
NOTE
The screen of the resolver cable must be correctly
connected to the de-coupling plate and connected to
chassis (earth) on the motor side.
NOTE
Always use screened motor cables and brake chopper
cables.
