MACHINE PARAMETERS.
(REF: 1402)
General machine parameters. Execution channels.
programmed feedrate. The rapid traverse will also be limited by channel parameter
FRAPIDEN.
FRAPIDEN
Rapid traverse in the channel for movements in automatic mode.
Possible values: From 0 to 500000.0000 mm/min / from 0 to 19685.03937 inch/min.
Default value: 0.
Associated variable: (V.)[ch].MPG.FRAPIDEN
Maximum feedrate in the channel for the program being executed, when rapid traverse for
the automatic mode is active (parameter RAPIDEN). If the parameter is set with a "0" value,
the feedrate is not limited.
This parameter does not the movements programmed in G00 or the threads. Movements
in G0 are carried out at the feedrate set in parameter G00FEED. The threads are executed
at the programmed feedrate.
Rapid traverse cannot exceed the value set in axis parameters G00FEED and FRAPIDEN
or the maximum feedrate set by PLC (variable (V.)PLC.G00FEED). Rapid traverse cannot
exceed the value set in axis parameter MAXFEED of the channel and the active feedrate
set by PLC (variable (V.)PLC.F).
MAXIMUM ACCELERATION AND JERK ON THE TOOL PATH.
MAXACCEL
Maximum acceleration on the machining path.
Possible values: From 0.0010 to 600000000.0000 mm/min / from 0.00004 to 23622047.24409 inch/min.
Default value: There is no maximum feedrate.
Associated variable: (V.)[ch].MPG.MAXACCEL
This parameter may be used to smooth the feedrate on the tool path by limiting the maximum
acceleration on it. Regardless of the value of this parameter, the CNC always respects the
dynamics of the axes involved in the path; i.e. it respects the acceleration set for each axis.
How to change temporarily the maximum acceleration defined.
The variable "(V.)[ch].G.MAXACCEL" may be used to temporarily change at a particular time
and in real time the value set by the machine parameter. The CNC assumes the change
immediately and stays active until M30 or reset is executed, in which case the CNC restores
the value set by the machine parameter. If the variable takes the value of ·0·, the CNC does
not apply any acceleration limit on the tool path, not even the one set by machine parameter.
MAXJERK
Maximum jerk on the machining path.
Possible values: From 0.0010 to 6E11 mm/min / from 0.00004 to 2.362E10 inch/min.
Default value: There is no maximum feedrate.
Associated variable: (V.)[ch].MPG.MAXJERK
This parameter may be used to smooth the feedrate on the tool path by limiting the maximum
jerk on it. Regardless of the value of this parameter, the CNC always respects the dynamics
of the axes involved in the path; i.e. it respects the jerk set for each axis.
How to change temporarily the maximum jerk defined.
The variable "(V.)[ch].G.MAXJERK" may be used to temporarily change at a particular time
and in real time the value set by the machine parameter. The CNC assumes the change
immediately and stays active until M30 or reset is executed, in which case the CNC restores
If "EXRAPID or rapid key" is the chosen option for RAPIDEN and the CNC has several channels, the
EXRAPID mark will only affect the corresponding channel. The rapid key, on the other hand, affects
simultaneously all the channels that may be affected at the time. If the active channel is in jog mode
and another channel is executing a program, when pressing the rapid key in the active channel (jog
mode), the rapid traverse will also be applied in the channel that is executing the program.
In a system where the rapid key may affect several channels at the same time, we recommend to choose
the "EXRAPID and rapid key" option or manage by PLC the behavior of the rapid key according to the
active channel and the selected work mode (jog or automatic).
