For axes which are mutually interpolated the k
v
factor must be the same, in order to avoid contour
distortion.

The K

factor in MP1810 is, in general, determined by the rapid traverse (MP1010) of the machine
and the lag, using the following formula:

The rapid traverse (maximum traversing speed) must be adjusted by the desired analog voltage (e.g.
9 V) on the servo-amplifier (see section "Commissioning and start-up procedure"). For each axis-
specific rapid traverse there is an analog voltage which is stored in machine parameter MP1050.
