MM4006 N S A l l o w generation of pulses on interpolation
Usage
■
IMM
■
PGM L 1 MIP
Syntax N S
Parameters N o n e .
Description T h i s command, together with ET command, verifies the correctness of data
entered by NB, NE and NI, NN before allow generation of pulses along the tra-
jectory. If a condition is not satisfied, the generation of pulses is disabled and
the command returns an error. If not, pulses are generated and at every
moment where a pulse is generated, the X and Y axis positions are stocked in
the global trace buffer and can be reread by TQ command.
The pulses are generated on pin 12 of the 25-pin auxiliary connector with a
pulse width of about 5 psec.
NOTE
This command, i f successful, erases effect of the global trace mode
defined previously by any GQ command.
NOTE
This command, if used, must precede immediately ET command.
Returns N o n e .
Errors D — Unauthorized execution.
Synchronization pulses generation impossible.
Rel. Commands N B — S e t trajectory element where the generation of pulses starts.
NE — S e t trajectory element where the generation of pulses ends.
NI — S e t step (curvilinear distance) between Synchronization pulses.
NN — S e t number of synchronization pulses to generate.
