Design Guide
Set-up example
In Illustration 7.9, a permanent magnet (PM) Motor is used
with resolver as speed feedback. A PM motor must usually
operate in flux mode.
Wiring
The maximum cable length is 150 m (492 ft) when a
twisted-pair type of cable is used.
NOTICE
Always use shielded motor cables and brake chopper
cables. Resolver cables must be shielded and separated
from the motor cables. The shield of the resolver cable
must be correctly connected to the decoupling plate and
connected to chassis (ground) on the motor side.
