Incorrect unit system
• With POWER ON
• After modifying MD
• Conversion factor assumed to be 1
• An illegal combination has been selected (conversion factor greater
than ten) for the units of the measuring system (position control
resolution) and the unit of the input system.
• Position control resolution for rotary axis < 0.5 · 10
-3
degrees and
the ordering data option for this is missing.
Correct the MD bits then switch the control off and on or include the
ordering data option ”Position control resolution for rotary axis < 10
-3
degrees”
