Yes: Valid
No: Invalid

Backlash

It sets the value of backlash of each
axis, only valid when parameter
―Backlash Compensation Valid‖ is set
―Yes‖.

0~1000 (

μ

m)

If parameter ―Screw Error Comp‖ is set as ―0‖, and parameter ―Backlash Compensation valid‖ as
―Yes‖, only backlash compensation is activated.

If parameter

―Screw Error Comp‖ is set as ―1‖, and ―Backlash Compensation valid‖ as ―Yes‖,

backlash compensation and unilateral error compensation are activated, used when backlash is
relatively constant; if

―Screw Error Comp‖ is ―2‖, forward error compensation and backward error

compensation are executed together, used when backlash is not constant.



Concept and Principle

Screw error consists of screw pitch error and errors caused by backlash.



Pitch Compensation:

Pitch error is caused by defect in manufacturing of screw and long-term wear, etc. In order to

improve precision, pitch compensation is needed. The sketch of screw is shown in Fig. 3-33. A
coordinate system is established, based on ―0‖ point on the screw as the reference point, nominal value
as X-coordinate, and actual value as Y-coordinate. Then ideal moving cur

ve is as curve ―1‖ in Fig. 3-34,

however, actual curve will be curve ―2‖ due to pitch error. That is to say, the Actual value is not the same
as its corresponding Nominal value, actual moving curve deviating from the ideal one, and their

difference is called error, i.e.:

Error = nominal mechanical coordinate

– actual mechanical coordinate
