Which products are affected?
Software Package Positioner V3.1
Positioner template
What happens?
When changing the machine parameters the 'Home position known' state is not reset.
When does the problem occur?
If the machine parameters under codes C1200-C1204 or C3000-C3001 are changed, these changes are adapted in the StandBy state of the template and the current position value is converted correspondingly. However, the 'Home position known' state remains unchanged although the home position has been shifted.
Possible diagnostics?
If the feed constant is doubled, the current position is doubled, too.
Thus, the reference to the home position is no longer identical. Nevertheless, g_bHomePositionAvailable = TRUE is indicated.
Short-term measures/recommendations?
Homing is to be executed again after changing the machine parameters.
Evaluation:
The machine parameters are not changed during the actual operation of a machine. Usually, the change of the machine parameters is preceded by an actual hardware change which is related to a repeated homing.
