Step Action
1.
UseP 530 - ENC_Encoder1SeltoselectthechannelforSercos:1st
encoder
2.
UseP 531 - ENC_Encoder2SeltoselectthechannelforSercos:2nd
encoder
3.
Selectionoftheencoderwhoseactualpositionvalueistobechanged,
withP 590 - ENC_ACOR_Sel
4. EnterinterpolationpointpitchinP 593 - ENC_ACOR_PosDelta
5.
Thecorrectionvaluesaredeterminedusingareferencemeasurement
system(e.g.laserinterferometer).Theinterpolationpointsforthevarious
directionswithinthedesiredcorrectionrangeareapproachedoneafter
anotherandthecorrespondingpositionerrorismeasured.
6.
Theinterpolationpoint-specificcorrectionvaluesareenteredmanuallyin
tablesP 595 - ENC_ACOR_VnegTab(neg.direction)andP 596 - ENC_
ACOR_VposTab(pos.direction).
7. Savevalues
8. Restartthedevice
9.
P 592 - ENC_ACOR_PosEndnowshowsthepositionendvalueofthe
correctionrange.
10.
Startcontrol(inpositioncontrolexecutehoming)andthenmovetoany
position.
11.
ThemomentarycorrectionvalueiswrittentoP 594 - ENC_ACOR_Val.
Thisvalueissubtractedfromtheapproachedpositionvalue.Thisapplies
toallpositions.Endposition=interpolationpointpitchmultipliedby
numberofinterpolationpoints(tablevalues)+startposition(onlyifstart
position≠0).

Position control
The direction of movement is produced when the time-related change in position
reference (speed pre-control value) has exceeded the amount of the standstill
window in the positive or negative direction.
