Note:
Pay special attention to the sign of nominal mechanical coordinate and actual mechanical coordinate, especially
when equipment like laser interferometer is used to measure the length. Calculate after the measured length is
converted to the corresponding mechanical coordinates, or a wrong result may occur.
3) Annotation: it must be in a separate line and started with semicolon. Its syntax is:
;<Annotation contents>
Note that semicolon must be the first character of the separate line, that is, no other character
should be in front of the semicolon, even blank space.
An example of screw error compensation file format:
;unit=mm
[X]
-570.025, 0.027, 0.083
-450.020, 0.025, 0.077
-330.015, 0.015, 0.068
-210.010, 0.000, 0.057
Compensation Method
Generally the value of screw error compensation can be measured by a laser interferometer, with
two ways for compensation.
1) File compensation. Save the measured value into the file and name it ―axeserr.dat‖, then save it to
the root directory of the USB flash disk. The system will then perform compensation automatically in
processing based on the data in the file. For the format of screw error compensation file, refer to its
introduction in 3.11.1.
2) Directly setting compensation on the interface. Turn to [Compensation (=)] screen under
[Parameters] function area, then press F7 (Leadscrew button), and then press F3 to set the
compensation parameters, as shown in Fig. 3-37.

Insert: continuous inserting of multi-blank-line prohibited; next inserting is allowed after previous one
is completed.
Import & Outport: compensation files can be copied from or to a U disk or other external storage.
Apply: i.e. save. After parameters are set, press Apply before restarting the software. Reboot is
