WinPC-NC Economy Parameter settings
Invert movement direction
There are two possible remedies if one of the motors is moving in the
wrong direction.
Changing over
the movement
direction
Either swap over the motor winding connections or change the
movement direction with this parameter. The direction signal for
controlling the motor is then inverted before being output.
Reference switch
This parameter enables you to define in which direction the axis is
moved in order to search for the switch. Movement clear from the
switch then takes place in the opposite direction.
Reference sequence
Reference movement of the individual axes takes place in a particular
sequence. Usually, it is necessary to move the Z-axis upwards first so
it is withdrawn from the workpiece. Then the two other axes move to
their reference points.
Possible faults
with reference
movement
After the machine is started up for the first time, there may be faults
with reference movement which can be remedied as follows:
• Axis moves in the wrong direction
Remedy : Define that the reference switch is at the other
end of the axis.
• Axis moves in the correct direction, but stops after reaching the
switch and does not move clear again
Remedy : Define the reference switch at the other end and
change the switch logic.
Maximum spindle speed
Speed control in
256 steps
WinPC-NC can control the speed of a drilling or milling spindle. It is
possible to define a speed for each tool, or the speed data is taken
from the NC files.
The maximum value defines the reference for step 256. All lower
values are calculated proportionately between 0 and this value, and
are output.
