If both - and + appear, the motion device is either disconnected or a
hardware failure exists. On power-up sequence, the controller checks
every axis for this case. If found, it assumes that no motion device is pre-
sent. The axis is marked with Unconnected on the display and all com-
mands for it will be ignored.
At the end of each axis information line an OK is displayed if no error has
been detected. If a problem is detected on one of the axes, the message
ERROR will appear.
2.3.3 Z e r o Display
During operation in Local Mode, the need may arise to force the current
position to become zero. This means that, without moving, the current
position is displayed and reported as zero. Any subsequent motion will be
referenced to this new zero location and the software limits will be recalcu-
lated to reflect the change while keeping their absolute position relative to
the stage.
To activate this function from the Manual Jog menu, press the ZERO k e y.
Using the keypad, enter the axis number you want to select or leave the 0
default to zero all active axes. Press the y l i b p k e y to execute the com-
mand.

2.3.4 R e l a t i v e Moves
A move is defined as a point-to-point motion. The initial point is the current
position and the ending point is the destination, or desired position.
There are two types of moves: relative and absolute. In this section we dis-
cuss the relative moves.
A relative move is defined as a move for which the destination is specified
as an incremental distance from the current position. Repeating a 1 mm rel-
ative move command, for instance, will advance the motion device 1 mm at
a time. For this reason, the relative motion is sometimes called incremental
motion.
