6.7.24 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 map 1) and instance 2 will represent menu 21 motor information
(motor map 2). The instance being used by the other dependant objects will be
determined by Pr
21.15 , to use the second motor map objects (instance 2), Pr 21.15
should be set to ON . Pr 21.15 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 6.25
AC Motor data object attributes below, the available attributes
and associated functions for the DC motor data object are shown in Table 6.27 DC
Motor data object attributes on page 55.
(* The MotorType attribute has no effect on drive operation, it is only used to provide information to
the user as shown in Table 6.26
Supported motor types
below).
