Axis-specific M/H functions

In general, user-specific M/H functions programmed in conventional DIN syntax are handled and executed for specific channels.

If the user wants to force axis-specific handling for each user-specific M/H function, he can also preassign them in the channel parameters P-CHAN-00039 and P-CHAN-00025.

Syntax:
m_default_outp_ax_name[<m_nr>]	<axis_name>

h_default_outp_ax_name[<h_nr>]

<axis_name>

<m_nr>	User-specific M function with axis-specific effect.
<h_nr>	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.

N.. S1000 M3 M20 M21 M22 H10 ;S and M3 act on the main spindle axis

;M20 acts on the S2 spindle axis

;M21 acts on the S2 spindle axis

;M22 acts on the Z axis

;H10 acts on the X axis

Notice

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 can also force an axis-specific output of M/H functions by the use of bracketed expressions:

Syntax:

<axis_name> [ [ M.. ] [ H.. ] { [ M.. ] [ H.. ] } ] { <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..	User-specific M function with axis-specific action.
H..	User-specific H function with axis-specific action.

Programing 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)

This gives the user the option of executing his specific M/H functions very flexibly by programming or configuring for specific axes or specific channels.
