13.13.3 Activation of the corrections
Parameter K165 allows the user to activate these corrections:
By default, there is no correction because K165 = 0. If K165 is equal to 1, 2, 3 or 4, the correction will be
activated only after the homing. The setting of parameters K165 to K169 will be done only after the end of a
movement.
13.13.4 Use
In order to monitor the effect of the correction on the scope, a new monitoring variable has been added:
monitoring M8. It represents the position reference in dpi before the encoder scaling and mapping correction.
Monitoring M0 represents the correction after the encoder scaling and mapping.
Remark: Once the corrections of the position are activated, there are also valid in interpolated mode with
the DSMAX (as shown above).
As the corrections are done with regard to the absolute position in dpi, the SET command which
changes the offset for the variable in upi can be used without affecting the correction.
Once the controller is powered on, K168.0=M8.0 can be executed to automatically set a null
correction at the current position. K169 will be modified by the user to change the correction of the
encoder scaling.
