In position synchronisation (par. 19-01 = 1 or 4) only the slave
marker is used; in marker synchronisation (par. 19-01 = 2 or 5)
both slave and master marker must be detected before count-
ing.
33-25 Marker quantity READY
Option:
Function:
Enter when a READY signal (O1) must be set. Enter the number
of marker pulses, i.e. a setting of 10 means that ACCURACY
must be present for 10 marker pulses before the READY signal
is set.
In position synchronisation (par. 19-01 = 1 or 4) only the slave
marker is used; in marker synchronisation (par. 19-01 = 2 or 5)
both slave and master marker must be detected before count-
ing.
33-26 Velocity filter
Option:
Function:
In speed synchronisation it is recommended to set a filter time
based on resolution. This is to avoid speed fluctuation at low
speed or when using low resolution of encoders. Please see fol-
lowing table:
Encoder Resolu-
tion

For all other types of synchronisation: Changing the sign of the
filter value enables the use of filtering the other types of syn-
chronisation. This means that unstable position or marker syn-
chronisation can be smoothened.
