Endless trigger
This mode is destined for applications where the encoder primarily moves in one direction as
in production lines and where equidistant sampling is needed. In order to use this mode, only
a trigger interval has to be parametrized.
Fig A1-2: Endless Trigger
Format
The comm
and has the following form
at: ETR <func
tion> <arg> where f
unction is:
0: Set start position ((int) arg = start position to set, see figure)
1: Set stop position ((int) arg = stop position to set, see figure)
2: Set trigger interval ((float) arg = trigger interval, see figure) Note that the interval can be
given in fractions of encoder counts.
3: Enable encoder (0: disabled, 1: enabled)
4: Enable triggering during return move, see figure. 0: disabled, 1: enabled.
5: Select encoder counter
6: reserved
7: Enable endless triggering (in this mode, start and stop positions are ignored, trigger events
will be generated on the current position and the trigger interval) 0: disabled, 1: enabled.
