Chapter 12 Robot Control Statements
12-43
Notes
(1) If the controller executes any relative motion command immediately
following an interrupt skip, then the subsequent relative motion will start
from the position where the robot stops. In program lines sandwiched by
the INTERRUPT pair, therefore, use an absolute motion command.
(2) The system does not perform a pass motion during INTERRUPT ON.
If the system finds the pass motion designated, all of then are executed in
the end motion.
(3) Turning an interrupt skip signal ON interrupts all motion commands
sandwiched by the INTERRUPT pair and stops all robot motions. Therefore
carefully design your robot system for multitasking if you use the
INTERRUPT.
Program Example
PRO1
TAKEARM 0
INTERRUPT ON
MOVE P,P0 'Motion command
.
.
.
INTERRUPT OFF
END
PRO2
TAKEARM 1
INTERRUPT ON
DRIVE(7,30) 'Motion command
.
.
.
INTERRUPT OFF
END
When the controller is running PRO1 and PRO2 programs concurrently in
multitasking mode, if an interrupt skip signal turns ON, then the controller
will interrupt all commands (MOVE in PRO1 and DRIVE in PRO2 in the
above example) running in both programs and make the programs
simultaneously proceed to the next step.
