The reference run is conducted for as long as the
Cycle Start key stays pressed. To interrupt the
reference run, release the key.
“Cycle stop” interrupts the reference run.
Monitoring EnDat encoders
If your machine is equipped with EnDat encoders, the control saves
the axis positions during switch-off. During switch-on, the CNC PILOT
compares for each axis the position during switch-on with the position
saved during switch-off.
If there is a difference, one of the following messages appears:
„ “Axis was moved after the machine was switched off.” Check the
current position and confirm it if the axis was in fact moved.
„ “Saved encoder position of the axis is invalid.” This message is
correct if the control has been switched on for the first time, or if the
encoder or other control components involved were exchanged.
„ “Parameters were changed. Saved encoder position of the axis is
invalid.” This message is correct if configuration parameters were
changed.
The cause for one of the above listed messages can also be a defect
in the encoder or control. Please contact your machine supplier if the
problem recurs.
