Control system response
At POWER ON and
RESET
, the retraction path is set as configured (MD), as is the state of
LFON
or
LFOF
and
LFTXT
or
LFWP
using machine data:
MD20150 GCODE_RESET_VALUES
from the corresponding G group.
Smoothed actual values
If lowresolution encoders are being used, smoothed actual values can be applied for constant coupled path and
axis motions.
Machine data:
MD34990 ENC_ACTVAL_SMOOTH_TIME
can be used to change the time constant for more effectively smoothed actual values for:
• Thread cutting with feedrate for
G33
,
G34
,
G35
• Revolutional feedrate for
G95
,
G96
,
G97
,
FRAPON
• Display of actual positions and actual speed/velocity
The larger the time constant, the better the smoothing of the actual values and the longer the overtravel.
