Resolver connection [X2A]
The 9-pin D-SUB connection [X2A] is used to evaluate standard resolvers. Single- and multi-polepair
resolvers are supported. The user can state the number of pairs of poles of the servo motor in
the “Motor Data” menu of the Metronix ServoCommander™ parameterization program so that the
ARS 2300 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 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.
