7.5.19 Motor data object
Class: 0x28 (40
10
)
There are 2 instances of the Motor data object. Instance 1 will represent menu 5 motor
information (motor 1) and instance 2 will represent menu 21 motor information (motor
2). The instance being used by the other dependant objects will be determined by Pr
0.11.045, to use the second motor map objects (instance 2), Pr 0.11.045 should be set
to Motor 2. Pr 0.11.045 is polled in the background task, so the user should be aware
that during motor map changeover, the RPM speed reference may not be accurate. The
available attributes and associated functions for the AC motor data object are shown in
Table 7.25 AC Motor data object attributes below.
Table 7.25 AC Motor data object attributes
(* The MotorType attribute has no effect on drive operation, it is only used to provide
information to the user as shown in Table 7.26 Supported motor types below)
