Procedure
Step Action
1. Openthemanualmodewindowandsetspeed-controlledmode.
2.
Motoroperatedatconstantspeed
l Resolver:1000rpm
l SinCosincrementalencoder:1to5rpm
3. SetP 549[0] - ENC_CH1_Corrto"ADAPT(2)=Autocorrection"
4.
Waitabout1–3minutes.Duringthistime,thecompensationalgorithms
willreachtheirsteadystate.Speedrippleshoulddecreaseafterabout1
minute.Thiscanbemonitoredwiththeactualspeedvalueinthescope
orwithP 550 - ENC_CH1_CorrVal.
5.
SetP 549[0] - ENC_CH1_Corrto"CORR(1)=Correctionwithsaved
values".
6. Saveinthedevice

NOTE
l Theroutinecanalsobekeptenabledpermanently.However,this
approachislessrobustandrequirescarefultestingtodetermine
whethertheimprovedencoderevaluationqualitywillactuallybe
maintainedduringcontinuousoperation.
l TheGPOCroutinewilldeterminetheparametersindividuallyfor
eachencoder.Ifthemotorisreplaced,theGPOCroutinemustbe
activatedagain.
