If 1000 is added to the previous choices the fixed offset is not executed before the marker cor-
rection has taken place.
33-24 Marker quantity FAULT
Option:
42
Function:
Enter how large the permitted tolerance for the occurrence of
the marker is. The factory setting "0" means all markers are
used. At every other setting only those markers are accepted
which are within the window. Example: Marker interval = 30000
and marker window = 1000. Only markers with an interval of
29000 to 31000 is accepted.
Function:
last marker pulse, i.e. the slave synchronises to the last detected
marker pulse. This is achieved by accelerating to this position.
next marker pulse: The slave waits for the next marker pulse
and synchronises to it.
once the master speed is reached marker correction to next fol-
lowing markers take place(may catch up slow down).
same as "0" but after master speed is reached.
same as "1" but after master speed is reached.
once the master speed is reached marker correction to closest
marker take place.
NB!
This parameter is only used in marker synchronising mode (par. 19-01 = 2 or 5).
Function:
Enter when a FAULT signal (O2) must be set. Input the number
of marker pulses, i.e. a setting of 10 means that ACCURACY
must be low for 10 marker pulses before the FAULT signal is set.
