Resolver connection

Resolvers are connected to X7 (9-pole Sub-D socket).
To avoid interference injection, only use shielded motor and encoder cables if an encoder
is used.
You can connect and operate:

When a resolver with a lower rotor impedance (Z
connected, the integrated overload protection limits the
excitation current which impairs the signal quality and
may distort the determined actual values.
