10.3Speed-/velocitylimits
l P 328[0] - CON_SCON_SMaxcanbeusedtosetthemaximumspeedlimit.
Inthedefaultsettingthespeedlimitisthesameastheratedspeedofthe
motor.Thepossiblesettingrangeis0-2000%.Theparametercannotbe
changedduringoperation.Achangeisonlyeffectiveafterrestartingthe
control.
l P 337[0] - CON_SCON_SMaxScaleenablesthetorquelimitsetinP 328[0]
tobescaledonline–thatis,duringoperation.
l ItisadditionallypossibleviaP 333[0] - CON_SCON_TMaxNegandP 334[0]
- CON_SCON_TMaxPostochangethetorquelimitfordifferentdirectionsof
rotationduringoperation.
l P 744[0] - MON_SDiffMaxisusedtospecifythepermissibledifference
betweenthesetpointspeedandtheactualspeed(trackingerror)in
revolutions.
l P 745[0] - MON_RefWindowisusedtodefinethepointatwhichthesetpoint
isconsideredtohavebeenreached.

10.4Positionlimitation
l Positionlimitingisonlyapplicableinpositioningmodeandwillbeenabled
onlyoncehomingissuccessfullycompleted(seeSection"Homing"onpage
252).
l P 2235[0] - MPRO_402_SoftwarePosLimitisusedtodefinethelower
positionlimit.P 2235[1] - MPRO_402_SoftwarePosLimitisusedtodefine
theupperpositionlimit.Thisfunctionisalsoreferredtoas“softwarelimit
switches”.
l Inaddition,P 743[0] - MON_UsrPosDiffMaxcanbeusedtodefinethe
maximumtrackingerror.
l P 746[0] - MON_UsrPosWindowcanbeusedtodefinethezerospeed
window(positionsetpointreached).
Positioning mode Function
Absolute
Beforeenablinganabsolutemotiontask,acheckismade
whetherthetargetisinthevalidrange–thatis,withinthe
softwarelimitswitches.Ifthetargetisoutside,nomotiontask
issignalledandtheprogrammederrorreactionasperP 30
Error Reactionsisexecuted.
Endless
Thismodecanonlybeusedwhenusingspeed-controlled
operation.Thedrivetravelsuntilasoftwarelimitswitchis
detected.Thentheprogrammederrorreactionisexecuted.
