Commands which have been extended
SYNC E R R
The return value informs, whether the synchroniza-
tion is running ahead (negative result) or behind
(positive result), if SYNCACCURACY is set to a
negative value.
E R RC LR
As of Version 2.1x ERRCLR also resets Bit 7 of the
control word of the VLT. Then the VLT messages no
longer need to be deleted.
LI N KGPA R
The command LINKGPAR tests whether the value
of the user parameter is within the specified range.
If not, the corresponding limit is used and this
value saved. This ensures that a display appears.
SYNCM
When defined in SYNCMSTART (62), the system
waits for the first evaluation of the marker pulses
on starting SYNCM and only then the offset
SYNCPOSOFFS (54) is applied.
#DE B UG
In addition to ON and OFF you can define NO
STOP. The system is not stopped, but internal
break commands update the line number when
the program is executed incrementally with
"DEVELOPM ENT"
→
"SING LESTE P F9"
The line numbers generated in this way can then
be laid on a VLT parameter 795-799 with
LINKSYSVAR and observed on the LCP display.

New Parameters
ESCCOND (70)
With ESCCOND you can determine how the VLT
will react to a program termination using [ESC].
SYNCMWINM (68) / SYNCMWINS (69)
The Marker Window Master and Slave shows how
large the permitted tolerance for the occurrence of
the markers is.

Parameters which have been extended
POSDRCT (28)
You can invert the evaluation of the encoder infor-
mation without changing the wiring (turning around
the motor leads or exchanging the A and B tracks
in the encoder).
O_BRAKE (48)
If an output is defined for the brake, this remains
active even when the program is terminated with
ESC.
SYNCPOSOFFS (54)
When SYNCM is started – in opposite to SYNCP –
the system waits for the first evaluation of the
marker pulses. Only then is the offset applied.
SYNCACCUARY (55)
Extended input range: A minus sign supplies the
synchronization error to SYNCERR with polarity
sign. It is then possible to tell whether the synchro-
nization is running ahead or behind.
SYNCMSTART (62)
Additional possibilities to define the start condi-
tions of the marker synchronization.
SYNCVFTIME (65)
Master filter for SYNCP and SYNCM
