Covered distance in current block in per thousand

Per thousand

The position within a motion block is defined in per thousand.

The per thousand display can be read as a display datum on the PLC interface (see Chapter HLI: Covered distance in the block – per thousand) when the current motion is interrupted.

Alternatively, the per thousand display can be specified as a purely required value without being previously read.

Continuation position with current block split by per thousand

If the restart position is defined by the relative display in relation to the motion block (per thousand), this position changes – within the range of resolution accuracy – even for restart when tool radius compensation is active and another tool radius is not.

This means that, if tool radius compensation is active, a tool with a different radius can be replaced in block search.

Value range of per thousand display

The per thousand display of a block is normally within the range [0, 1000].

Per thousand display with two inserted polynomial blocks

If only one block is inserted by the CNC between two original blocks (e.g. when #HSC [OPMODE = 1]), its distance may be between [0,2000]
