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 saved in parameter 0x2C43 (0x3443) must be adapted to the used resolver.
If the stator coils are excited with 4 kHz, the apparent impedance of the connected resolver
must not fall below a value of 65 ohms. If smaller 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.
