Setup mode
2.
Set the Absolute Datum using Digifind. Press the slider bar close to
the particular axis to set the datum. For the W-axis, the DRO goes to
the next screen automatically once it senses the reference output
from the encoder.
3.
Bring the encoder near to the machine reference mark and press
. The new machine reference is set.
The default value for the machine reference is zero.
Zero App. Distance
. This is the bar graph that is shown below the axis
display. It is available in all Distance to go modes. You can also force the
bar graph on using the Functions list. The value of this setting is the limit
for the bar graph. The default value is 1.000.
Calibrate Axis
. You use this to compensate for errors arising due to wear
and tear, encoder misalignment, etc. You can calibrate each axis for
Linear Errors or Segmented Errors as applicable. The detailed procedure
for calibration is explained in Calibrate axis on page 14.
Apply Compensation
. You use this to program the type of compensation
to be applied to the selected axis. There are three options: {
none
}, {
l.
comp
} and {
s. comp
}. The none option applies a linear calibration factor
of 1.0. The default compensation type is none.
Axis-specific settings (angular type)
This option is only available for the W-axis.
Counts per Revoln
. This parameter defines the encoder counts per
rotation. You can enter this value if it is known or there is an automatic
calibration process for finding the CPR value. In the automatic process,
you are prompted to pass two reference marks in the same direction. The
DRO counts within them, and sets the CPR value. The default value is
4096.
Resolution (Deg.)
. This parameter defines the Display resolution in
degrees. The default value is 0.1 degrees.
Reference Mode
. This defines which reference mode to select, Internal or
External. For Internal mode, the DRO uses the encoder reference mark
for referencing. For External mode, the DRO senses an external input
(Input 4) first and then references the DRO on the encoder internal
reference mark. You use this mode where one machine rotation
corresponds to more encoder rotations due to gear coupling. The default
is Internal.
Axis Direction
. This defines the counting direction of the encoder,
clockwise (CW) or counter-clockwise (CCW). The default is CW.
Count Mode
. There are two options:
Rollover: The angle rolls back to zero after 360.
Continuous: The angle continues accumulating after 360.
The default is Rollover.
Machine Reference
. This is similar to the machine reference for the linear
type, except that the value is set in degrees.
Display Mode
. The angular axis is configurable for two possible options.
DDMMSS. Degrees:Minutes:Seconds (00:00:00).
DDDEC. Decimal Degrees (0.0000).
The default value is DDMMSS.
Axis Lock
. There are two options:
Axis Lock On
Axis Lock Off.
Axis Lock On stops you axis setting in Absolute mode. Only the operator
can perform referencing. The default value is Axis Lock Off.
Zero App. Angle
. This is similar to the zero approach distance for the
linear mode, except that the setting is in angular mode. The default value
is 10.
