360 Motion Object Attributes
Change Pos Reference
The Change Position Reference bit attribute is set when the Servo loop has
switched to a new position coordinate system. The Logix processor to uses
this bit when processing new position data from the servo drive to account for
the offset implied by the shift in the reference point. The bit is cleared when
the Logix processor acknowledges completion of the reference position
change by clearing its Change Cmd Reference bit.
Drive Fault Bit Attributes All of the fault bit attributes defined below can be handled by the
ControlLogix processor as a Major Fault by configuring the associated Group
Object’s “General Fault Type Mechanism” attribute accordingly. Otherwise
any specific fault handling must be done as part of the user program.
