Resolver
Resolvers are connected to X7 (9−pole Sub−D socket).
The use of third−party resolvers is permissible. For this purpose the number of pole pairs of
the resolver in C00080 must be adapted to the resolver used. When the stator coils are
excited with 4 kHz, the apparent impedance of the connected resolver must not fall below
65 Ohm. When lower impedances are connected, the overload protection integrated in the
resolver output limits the output current and can falsify the resolver evaluation.
Resolvers are operated in reverse mode:
ƒ Supply to the sine and cosine track,
ƒ Both signals are controlled in a way that the current flow on the reference track is
reduced to zero.
