VMODE = NC
This parameter is specified in s
-1
(1/s).
In NC Mode the loop gain is normally specified rather than the deceleration distance
6
.
The internal gain is calculated from this gain value together with the VMAX and POSITION parameters.
Calculation of the internal control gain
In NC Mode the following error at maximum speed is calculated by means of the loop gain. This following
error corresponds to the deceleration distance with stroke-dependent deceleration. The conversion and
therefore also the correct data demands related to the control system are relatively simple if the relation-
ship described here is taken into account.

The loop gain is alternatively defined as a KV factor with the unit (m/min)/mm or as Vo in 1/s. The conversion is KV
= Vo/16.67.
