Display Configuration
The Display Configuration form is where which axes can be selected
for display, and in what order. The following additional setups are
also available.
8 Scroll to the desired display, and press ENTER.
8 Press the ON/OFF soft key to turn the display on, or off. Press the
LEFT, or RIGHT arrow key to select the axis label.
8 Scroll to the Input field. Press the numeric key associated with the
encoder input on the back of the unit.
8 Press the + or - soft keys to couple a second input with the first. The
input numbers are displayed next to the axis label indicating that the
position is a coupled position (i.e. “2 + 3”).
8 Scroll to the Display Resolution field. Press the COARSER, or FINER
soft keys to select the display resolution.
8 Scroll to the Angle Display field if the encoder type is set to Rotary.
Press the ANGLE soft key to display the position as 0° - 360°, ±
180°, ± infinity, or RPM.
Error Compensation
The distance a cutting tool travels, measured by an encoder, can in
certain cases, differ from the actual tool travel. This error can occur
due to ball screw pitch error, or deflection and tilting of axes. This
error can either be linear,or non-linear. You can determine these errors
with a reference measurement system, such as gauge blocks, laser,
etc. From an analysis of the error, it can be determined which form of
compensation is required, linear, or non-linear error.
The 300S provides the opportunity to compensate for these errors,
and each axis can be programmed separately with the
appropriate compensation.
Error compensation is only available when using
linear encoders.
