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)
