C.2.65.1.
Profiling Bit in the MOTIONSTATUS Axis Parameter
The profiling bit in the MOTIONSTATUS axis parameter indicates that the axis is in the
profiling mode (G1, G2, G3 or other contoured motion). This bit will be TRUE even
during a manual feedhold or when the MFO = 0, however, it will be false during a
feedhold due to Jog/Interrupt, ONGOSUB, or a canned function.
C.2.65.2.
Moving Bit in the MOTIONSTATUS Axis Parameter
The moving bit in the MOTIONSTATUS axis parameter indicates that the axis is in the
profiling mode (G0, HOME or other contoured motion). This bit will be TRUE, even
during a manual feedhold or when the MFO = 0, however, it will be false during a
feedhold due to Jog/Interrupt, ONGOSUB, or a canned function.
C.2.66.
MOVEQDEPTH
The move queue depth parameter indicates how many commands are waiting to be
executed from that axis motion command queue.
C.2.67.
MOVEQSIZE
The move queue size parameter indicates the maximum number of motion commands that
are permitted in the queue.
C.2.68.
PGAIN
This axis parameter determines the gain of the position loop for the selected axis. Refer to
the UNIDEX 600 Hardware Manual for a description of how this parameter functions in
the servo loop. Note, that you may use the AutoTune feature, within the AerTune.exe
utility (on the Tools menu) to automatically determine servo loop gains for a torque mode
axis.
If the PGAIN axis parameter can not be increased greater than 1, without producing an
instability in the axis, its units may be rescaled.
C.2.69.
PHASE_SPEED
Refer to the BASE_SPEED axis parameter for a description of this parameter.
C.2.70.
PHASEAOFFSET
This axis parameter is used with the PHASEBOFFSET axis parameter to null any offset
in the DAC’s (commands) output to the drive for phase A (and Phase B) of a brushless
motor. Brush motors utilize the DACOFFSET axis parameter.
The value is entered as a signed number representing the number of D/A counts (+/-)
required to bring the DAC output command to zero volts. This value is added to all motor
command values before being output to the DAC.
For example, if an axis has a 60 mV (.060 volt) offset, -392 would be entered for this
parameter. This is calculated by dividing the offset by the voltage value of each step of
the DAC. UNIDEX 600 has a 16-bit DAC (+/- 32767 counts), generating a +/- 10-volt
