values (in bits) from the desired

proportional scaling. In addition, the
jump speed and mark speed should be
adjusted.

SetPosAcknowledgeLevel
– The limit value must be specified related to a
16-bit position range.
– The default start behavior is for the scan system
to set the limit value to 0.28% of the full
angular range of an axis (LSB16 or 1/65536,

If other limit values are desired, they must be

frequent system safety shutdowns due to
