Chapter 2 BASIC OPERATION
2.1
Power on
Function: Power on then SW4000 enter normal display state.
It can memorize the following parameter after power on.
A. The scale position where power off;
B. ABS/INC/SDM mode;
C. Shrinkage is enabled or disable;
D. Metric/Imperial mode;
The origin of the linear scale must be searched again if the scale is moved when power off.
Note: Normal display state
The state DRO automatically enters after on or exit from “STEUP”. In normal
display state, X window, Y window and Z window displays the current value of
X axis, Y axis and Z axis separately. The message window displays “ABS”,
“
INC” or “SDM XXX” (indicate the Number of SDM coordinate, with a range
of 000—999).When user switch among ABS/INC/SDM, MM/INCH or shrinkage / Un-shrinkage, DRO will not
leave this state. When you enter CALCULATOR function, input data to X (or Y or Z) axis, function of searching
the Reference point (RI) of the linear scale or special function (BHC: BHL: ARC: SLOPE PROCESSING and
EDM function): DRO is not in the normal display state.
2.2
Zeroing
Function: Zero the designated axis in normal display state. Zeroing is used to set the current point as datum
point.
Note: 1 The axis can’t be zeroed when DRO is in other states (for example: in the state of calculating function
or in special function). DRO should return normal display state;
2 The axes can be zeroed in ABS/INC/SDM states;
3 When zero in ABS coordinate, INC display value is cleared simultaneously. Zeroing in INC
coordinate has no effect on ABS and SDM display value.
4 Press the zero key of the same axis will cancel above zero operation
if the scale kept still after zero.
5 zero is means that set the current point as the origin point of current axis.
Example 1: Set the point O (as the figure illustrated) as datum
STEPS:
1)
Return normal display state;
2)
Move the machine table: and align the lathe tool with point O.
The DRO displays as the right figure.
3)
Press
to zero X axis,
