100256 master for synchron positioning
Description
The block generates an actual master position with limited or endless position range
specified by the parameter
G30
. The master encoder is set via the parameter
G27
. The
gear ratio which ensures the generation of the desired master units is set by the
parameters
G46
,
G47
,
G48
and
G49
.
The output of the block contains the actual master position
XMstrLim
(limited position
range) or
XMstrEnd
(endless position range), the related timestamp
XMstrTS
and the
master speed
MstrVel
. The output
Over/Und
indicates an overflow of the circular length
G40
by outputting a "1" on this output for one cycle. A "-1" is indicated for one cycle for an
underflow under 0.
A master offset can be set with the parameter
G51
.
A master speed offset can be set with the parameter
G52
. This is primarily used to
simulate a rotating master.
