Setting the spindle parameters
Fig.7-16: NC parameter axes
Fig.7-17: Parameter setting for axes: travel range, velocity, acceleration
Two travel range limits TrvLim[1] and TrvLim[2] can be defined for each axis.
Switching between these two travel ranges can be controlled via the PLC. If
you need only one travel range, we recommend that you set the two travel
ranges to the same limits.
Setting of the parameters for the gear (n1, n2), spindle pitch (k) and
position polarity (p) is explained in
Drives" on page
To set the spindle parameters, you must first decide whether you need a spindle
or a spindle C-axis. The basic projects of the MTXmicro each feature precon‐
figured spindle C-axes. You should define a pure spindle only if there is no
position encoder available for the spindle.
When do you need a spindle C-axis?
A turning machine needs a spindle C-axis if one of the following functions is
required:
● Face transformation COORD(3))
● Cylinder jacket transformation (COORD(1..2))
● Thread cutting (G33)
A spindle C-axis is required on a milling machine or on the tool spindle of a
turning machine for the following functions:
