[ \RefNum ] (Reference Numeric value) Data type: num<br />

Axis position defined in degrees (mm for linear axis). The position must be inside<br />

the normal working range.<br />

The argument is only to be defined together with the argument \Short, \Fwd or<br />

\Bwd. It is not allowed together with the argument \Old.<br />

Same function as \RefPos but the position is defined as a numeric value to make<br />

it easy to change the position manually.<br />

[ \Short ] Data type: switch<br />

The measurement system will change a whole number of revolutions on the axis<br />

side so that the axis will be as close as possible to the specified \RefPos or \Ref-<br />

Num position. If a positioning instruction with the same position is executed after<br />

IndReset, the axis will travel the shortest route, less than ±180 degrees, in order<br />

to reach the position.<br />

[ \Fwd ] (Forward) Data type: switch<br />

The measurement system will change a whole number of revolutions on the axis<br />

side so that the reference position will be on the positive side of the specified<br />

\RefPos or \RefNum position. If a positioning instruction with the same position<br />

is executed after IndReset, the axis will turn in a positive direction less than 360<br />

degrees in order to reach the position.<br />

[ \Bwd ] (Backward) Data type: switch<br />

The measurement system will change a whole number of revolutions on the axis<br />

side so that the reference position will be on the negative side of the specified<br />

\RefPos or \RefNum position. If a positioning instruction with the same position<br />

is executed after IndReset, the axis will turn in a negative direction less than 360<br />

degrees in order to reach the position.<br />

[ \Old ] Data type: switch<br />

Program execution<br />

Keeps the old position. Note that resolution is decreased in positions far away<br />

from zero.<br />

If no argument \Short, \Fwd, \Bwd or \Old is specified - \Old is used as default<br />

value.<br />

When IndReset is executed, it changes the independent axis back to normal mode. At<br />

the same time, the measurement system for the axis can be moved by a whole number<br />

of axis revolutions.<br />

The instruction may also be used in normal mode in order to change the measurement<br />

system.<br />
