308 Motion Object Attributes
Axis Control Bit Attributes
Abort Process Request
When the Abort Process bit is set, the servo module disables any active
process, such as a tuning or test process.
Shutdown Request
When the Shutdown Request bit is set, the servo module forces the axis into
the shutdown state which opens the OK contact and zeroes the DAC output.
Zero DAC Request
When the Zero DAC Request bit is set, the servo module forces the DAC
output for the axis to zero volts. This bit only has an affect if the axis is in the
Direct Drive State with the drive enabled but no servo action.
Abort Home Request
When the Abort Home Request bit is set, any active homing procedures are
cancelled.
Abort Event Request
When the Abort Event Request bit is set, any active registration or watch event
procedures are cancelled.
Change Cmd Reference
The Change Command Reference Request bit attribute is set when the Logix
processor has switched to a new position coordinate system for command
position. The servo module processor uses this bit when processing new
command position data from the Logix processor to account for the offset
implied by the shift in the reference point. The bit is cleared when the Servo
module acknowledges completion of the reference position change by clearing
its Change Position Reference bit.
