5000 SyncPos option
67 MENCODERTYPE
This parameter determines the type of master
encoder: incremental or absolute encoder.
Content
Type of encoder for encoder 0 (Master)
Parameter Group
AXE
Value range
0 … 2 ★ 0
0 = Incremental encoder
1 = Absolute encoder, standard ca. 262 kHz
2 = Absolute encoder, ca. 105 kHz
NB!
When selecting 1 or 2 (absolute encoder) the
following commands can not be used: DEF
ORIGIN, HOME, INDEX, IPOS, MIPOS and
WAITNDX.
The use of SYNCM should be avoided as it will not
function correctly.

indow Master SYNCMWINM shows
how large the permitted tolerance for the occur-
rence of the markers is.
With the works setting “0” the window is not moni-
tored, which means that it is always synchronized
to the next marker even if this has a considerably
larger interval.
At every other setting only those markers are ac-
cepted which are within the window. If there is no
marker within the tolerance window the correspon-
ding flag (SYNCSTAT) is set and no marker correc-
tion takes place. The corresponding other marker
is also ignored and only corrected the next time –
i.e. no catching up to the next marker.
When SYNCM is started the monitoring only begins
when the first marker has been found.

Value range
0 … MLONG or. max. Marker interval
SYNCMPULSM (58) ★ 0
0 = The window is not monitored.
1 … MLONG = Only one marker is accepted
within the window. If no marker
is within the tolerance window,
the corresponding flag
(SYNCSTAT) is set and no
marker correction carried out.
This flag can be reset with an
interrupt (ON STATBIT).
Sample
Marker interval SYNCMPULSM = 30000
Tolerance window SYNCMWINM = 1000
Only one marker within an interval of 29000 to
31000 is accepted.
