6.6Channel2:InterfaceX6
Image 6.3: Encoder configuration channel 2 (X6) screen
This screen is used to select the encoder for channel Ch2. This channel is used to
measure position changes periodically and add them up cyclically – this is referred
to as “cyclical evaluation”. Encoder channel Ch2 does not feature an absolute value
interface. In addition to evaluating resolvers, this channel can also be used to
capture “simple” SinCos signals (up to a max. of 1 kHz and with no zero pulse).
Resolvers must always be evaluated using encoder channel Ch2 (P506 - ENC_
CH2_Sel = RES(1)). The resolver pole pairs are set via P560[0] - ENC_CH2_Lines.

Resolver basics and requirements
The connected resolver must meet the following criteria:
l Ccw(positivesignalprogresscorrespondstoananticlockwisedirection
whenlookingattheshaftfromabove)
l Notransformationphaseshift
l Transformationratioofapprox.0.5
GPOC is a special KEBA online process for improving the quality of SinCos signals
before they are used to calculate a position. If Sel = RES(1) or Sel = SINCOS(2), this
process may come in handy. For details see Section "Signal correction GPOC (Gain
Phase Offset Correction)" on page 75.
