4.8.3 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:
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 4 kHz
Impedance Z
RO
= (R
RO
+ j X
RO
) = 90.9 Ohms (max.)
When a resolver with a lower rotor impedance (Z
RO
) is
connected, the integrated overload protection limits the
excitation current which impairs the signal quality and
may distort the determined actual values.
