MACHINE PARAMETERS.
(REF: 1402)
Machine parameters for the axes and spindles.
When activating function G201, the feedrate assumes instantaneously the value set by
IPOACCP.
LEADSCREW ERROR COMPENSATION.
LSCRWCOMP
Leadscrew error compensation.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Yes / No.
Default value: No.
Associated variable: (V.)[ch].MPA.LSCRWCOMP.xn
This parameter indicates whether the axis uses leadscrew error compensation or not.
LSCRWDATA
Leadscrew compensation table.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
This parameter shows the table to define the leadscrew error compensation. The table shows
the following parameters to configure it.
NPOINTS
Number of points in the table.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 1000.
Default value: 0 (there is no table).
Associated variable: (V.)[ch].MPA.NPOINTS.xn
Parameter included in the LSCRWCOMP table.
The leadscrew error compensation table can have up to 1000 points.
Considering the following values for the Y axis:
G00FEED: 1000 mm/min.
JOGFEED: 100 mm/min.
MAXMANFEED: 120 mm/min.
IPOFEEDP: 50%
MANFEEDP: 50%
When executing the following blocks:
N10 G201 #AXIS [Y]
N20 G1 Y100 F1000
At block N20, the maximum execution feedrate of the Y axis is not 1000 mm/min (G00FEED), but 500
mm/min due to the 50% limitation of IPOFEED over G00FEED. Therefore, in spite of the programmed
feedrate "F1000", the axis will move at 500 mm/min due to the limitation in G201.
If while the execution, the Yaxis is moved via JOG panel, a 100 mm/min feedrate (JOGFEED) should
be added. However, the maximum jogging feedrate will be 60 min/min because it has been limited
to 50% of MANFEEDP over MAXMANFEED.
Therefore, the Y axis will move at 560 mm/min when combining the automatic and jog modes.
