Note

Name Type DIS DIS format CFG List

EXTPOL2−PHIN ph 1425/2 ph 1374/1 Position input

EXTPOL2−STAT d 13461 − − HIGH = extrapolation on

LOW = new data at input −PHIN

EXTPOL2−LIM d 13462 − − HIGH = time limit of C1379 exceeded, extrapolation is cancelled or

master angle is in standstill

LOW = time limit not exceeded, master angle running

EXTPOL2−PHOUT ph 13461 − − Extrapolated position of input PHIN

EXTPOL2−DFOUT phd − − − Extrapolated speed difference signals

The output may be only used up to max. 10 extrapolation cycles per ms

(C1379 = max. 10 ms)

Tip!

Please observe the computing time of the FBs.
