3.2.21.1 Evaluation of the following error
The actual following error signal is generated by the function block CCTRL (output CCTRL−POUT)
and is read at CERR1−PHI−IN (see e.g. signal−flow diagramm, configuration 1000).
In the function block it is compared with the configurable following error limit CERR1−LIM. If the set
limit is exceeded, the following error warning is output at CERR1−ERR.
Input signal Output signal
CERR1−PHI−IN Within the window CERR1−ERR = LOW
Outside the window CERR1−ERR = HIGH
0 CERR1−PHI−IN
C1380 CERR1−LIM CERR1−LIM C1380
Hyst
CERR1−LIM generates a window around 0 inc.
3.2.21.2 Definition of the following error limits
l The following error limit is defined at the input CERR1−LIM.
l The limit for the following error pre−warning is determined via the reduction value
CERR1−WFAC.

Note!
The input values at CERR1−LIM are limited to a maximum of 4194300 inc
(4194300 inc = 63.9 × motor revolutions).
