Writing machine data (#MACHINE DATA)

Release Note

The availability of this function depends on the configuration and on the version scope.

This command permits a change in axis-specific machine parameters in the NC program. The new values are valid program global. They are overwritten by the next update of machine data lists at controller start-up.

Notice

An active path interpolation is stopped until the new parameter is adopted and the value is effective. Any rotating spindles are not stopped.

Syntax:

#MACHINE DATA [<mode>] [ AX<name> | AXNR=.. <Param_ID> =.. | <Param_ID>{.<idx>}<value> |

AXPARAM "<string>" [ WAIT ] ]

<mode>

Synchronisation mode

---: Synchronisation at decoding level (initial state)

SYN: Synchronisation at interpolation (real time) level

AX=<name>	Name of the related axis or spindle where a new axis-specific parameter is to be written
AXNR=..	Logical axis number of the path axis or spindle where a new axis-specific parameter is to be written. Positive integer.

Attention

No plausibility check is conducted for the logical axis number. The operator is solely responsible for making the correct entries. A change to any parameter value with #MACHINE DATA causes the complete axis parameter list to be retransferred to the NC channel. Axis parameter values previously changed using other NC commands (e.g. software limit switches via G98/G99) are overwritten and are no longer valid in the NC channel.

<Param_ID> =..

Axis parameter in ISG notation (P-AXIS-xxxxx) with new value in the unit of the axis parameter list [AXIS].

<Param_ID>
{.<idx>}<value>

With axis parameters that address an array, the corresponding element is written by the extended specification of point and index (e.g. P-AXIS-00209.0).

Notice

A slave axis in a hard gantry combination can only be addressed by the logical axis number.

The following axis parameters are available via predefined keywords (Param_ID):

Param_ID	Meaning
P-AXIS-00001	Non-linear velocity profile: Axis acceleration at velocity increase
P-AXIS-00002	Non-linear velocity profile: Axis deceleration at velocity decrease
P-AXIS-00004	Acceleration in rapid traverse (G00)
P-AXIS-00005	Linear velocity profile: Acceleration step 1 in rapid traverse (G00)
P-AXIS-00006	Linear velocity profile: Acceleration step 2 in rapid traverse (G00)
P-AXIS-00008	Permissible axis dynamics: Maximum permissible axis acceleration

P-AXIS-00012	Linear velocity profile: Acceleration step 2 at feed interpolation (G01, G02, G03)
P-AXIS-00045	Minimum distance (safety distance) between two collision axes
P-AXIS-00056	Maximum difference after deselecting tracking mode
P-AXIS-00075	Gantry operation: Velocity for compensating for static offset between master and slave axes due to differences in measuring systems
P-AXIS-00099	Acceleration factor k_v for P positional control
P-AXIS-00103	Size of backlash
P-AXIS-00109	Maximum permissible velocity override for independent axis and spindles
P-AXIS-00151	Maximum transient time to reach the exact stop window

P-AXIS-00168	Maximum position lag
P-AXIS-00169	Minimum position lag
P-AXIS-00172	Type of position lag monitoring
P-AXIS-00195	Non-linear velocity profile: Ramp time for acceleration down-gradation

P-AXIS-00201	Minimum permissible ramp time of the drive to limit axis jerk
P-AXIS-00208	Maximum feed of compensation motion after deselecting tracking operation
P-AXIS-00209	Rapid traverse velocity G00

P-AXIS-00212	Permissible axis dynamics: Maximum permissible axis velocity
P-AXIS-00216	Minimum permissible axis velocity for spindles. Below this velocity, the rotational speed monitor in the position controller supplies the "speed zero” state
P-AXIS-00217	Factor to calculate the actual rotational speed at which the "speed setpoint reached" state is signalled.
P-AXIS-00218	Minimum homing velocity
P-AXIS-00219	Maximum homing velocity
P-AXIS-00221	Linear velocity profile: Changeover speed in feed interpolation (G01, G02, G03) between velocity ramp 1 and velocity ramp 2
P-AXIS-00236	Size of control window for exact stop
P-AXIS-00414	Maximum position offset for distance control

AXPARAM "<string>"	Alternative syntax: Axis parameter with complete structure path and value in internal notation of the axis parameter list [AXIS] (see example). It is possible to write all axis parameters.
WAIT	This keyword may only be used in conjunction with the synchronised setting (SYN) of an axis parameter. If a WAIT is programmed, program decoding is also interrupted (implicit FLUSH) and the program waits until the new parameter is adopted and becomes effective in the NC channel.

Programing Example

Writing machine data

N10 G00 X100 (Position at rapid traverse velocity acc.)

(to default setting after start-up)

N20 #MACHINE DATA SYN [AX=X P-AXIS-00209=80000] (New rapid traverse velocity)

N30 ... (The new rapid traverse velocity applies in the following program sequence).

Alternative with axis list notation:

N20 #MACHINE DATA SYN [AX=X AXPARAM="getriebe[i].vb_eilgang 80000"]

(New rapid traverse velocity)

For a spindle axis:

Alternative with axis list notation:

N20 #MACHINE DATA SYN [AX=S P-AXIS-00109=1200] (New velocity override)

Set a software limit switch and wait in the channel:

N20 #MACHINE DATA SYN [AX=X AXPARAM="kenngr.swe_pos 15000000" WAIT]

Set the rapid traverse velocity for gear stage 1 with index:

N20 #MACHINE DATA SYN [AX=X P-AXIS-00209.1=80000]
