Axis-specific M/H-functions

In general user-specific M/H-functions programmed in conventional DIN syntax are handled and executed channel-specifically.

If the user wishes to force axis-specific handling for specific M/H-functions, he has the option of defining them additionally in channel parameters list [1]-7/-8 so that they act axis-specifically:

m_default_outp_ax_name[ <m_expr> ]  <axis_name>

or 

h_default_outp_ax_name[ <h_expr> ]  <axis_name>

<m_expr> User specific M-Function with axis specific effect.

<h_expr> User specific H-Function with axis specific effect.

<axis_name> Axis name of the axis on which the M/H-function is to act. Path axes and spindle axes are permitted in this case.

Programming example

Extract from channel parameters list [1]:

Axis-specific M/H-functions 1:

If an axis-specific M/H-function is programmed in a spindle-specific bracket expression, the default setting is ignored and the M/H-function acts on the corresponding spindle axis.

Moreover, for path axes, the NC-program includes the option of also forcing axis-specific output of M/H-functions by use of bracketed expressions:

<axis_name>[ M<expr>  H<expr> { M<expr>  H<expr> } ] { <axis_name>[ ... ] }

<axis_name> Axis name of the axis on which the M/H-function is to act. Only path axes are permitted in this case.

M<expr> User-specific M-function with axis-specific action.

H<expr> User-specific H-function with axis-specific action.

Programming example

:
N10 S1000 M3 X100 X[M20 H12] Y[H10] (S, M3 act on the main spindle axis)
(M20, H12 act on the X-axis)
(H10 acts on the Y-axis)
:

The user thus has the option of executing his specific M/H-functions very flexibly by programming or configuring axis-specifically or channel-specifically.
