Resolver connection [X2A]
The 9-pin D-SUB connection [X2A] is used to evaluate standard resolvers. Single- and multi-pole resolvers are supported. The
user can state the number of pairs of poles of the servo motor in
the "Motor Data" menu of the item Motion Soft
parameterization program so that the
item C 1-Series determines the speed correctly. However, the number of pairs of poles can also be identified automatically.
The number of pairs of poles of the motor (P
0Motor
) is always an integer multiple of the number of pairs of poles of the resolver
(P
0Resolver
). Wrong combinations such as, for example, P
0Resolver
= 2 and P
0Motor
= 5 lead to an error message during motor
identification.
The resolver offset angle, which is determined automatically during the identification, is readable and writeable for service
purposes.

Encoder connection [X2B]
At the 15-pole D-Sub connection [X2B], motors with encoder can be fed back. The possible incremental encoders for the
encoder connection are divided into several groups. If you want to use other types of encoders, please contact your sales
representative.
