To add to the current home calibration data:

press the

softkey

cursor to the position you want

key-in the new data

press

[TRANSMIT]

Important: If a parameter value that is out of range is entered, the error

message “PARAM VALUE OUT OF RANGE” appears in row 0 (zero) of

the screen. If an invalid value such as a float value (decimal number)is

entered where an integer is expected, the error message “INVALID

INPUT VALUE” appears in row 0 (zero).

Press the

{UPDATE & EXIT}

softkey to save the modified home

calibration data. The control then returns to softkey level 4.

PARAM

The online axis calibration parameters specify the commanded position
and the actual position or the difference between the commanded position

and the actual position of a machine axis.

Once any axis calibration parameter value is altered, the axis is marked as

unhomed. Homing operations are disabled while the axis values

are updated.

Modified Axis Calibration Parameter values for an axis become active

once the axis has been homed (assuming the axis has this feature).

If no axis data has been entered, the control displays the axis calibration

screen shown in Figure 40.1. If axis data has previously been entered for

an axis, the control displays the axis calibration screen shown in

Figure 40.2.

Important: To avoid the accidental loss of your axis calibration data you

should back up the axis calibration points both to control memory (page

40-16) and to a peripheral device (page 40-21). You can then restore these

calibration points whenever necessary.
