4.8.3 Resolver connection

Resolvers are connected to X7 (9-pole Sub-D socket).

To avoid i nterference injection, only use shielded motor and encoder cables if an encoder

is used.

You can connect and operate:

ƒ Resolvers

– Parameterisation of the number of pole pairs in C00925

– Lenze setting: Number of pole pairs = 1.

ƒ Multipole resolvers with a number of resolver pole pairs  2

ƒ Resolvers of other manufacturers

Please ensure compliance with the technical limiting values of the resolver:

Description Rated value

Cable length (system cable is recommended) Max. 150 m

Number of resolver pole pairs 1...n

Carrier frequency of the excitation voltage 4kHz

Impedance Z

=(R

+jX

) = 90.9 Ohms (max.)

When a resolver with a lower rotor impedance (Z

)is

connected, the integrated overload protection limits the

excitation current which impairs the signal quality and

may distort the determined actual values.
