The
command allows you to simulate the activation of specific limit inputs (without actually wiring
LIMEN
the inputs to the drive) by disabling them and setting them to a specific level (ON or OFF). This is useful
for testing and debugging your program (see program example below).

Example:
DEL tsting
; Delete program called "tsting"
DEF tsting
; Begin definition of program called "tsting"
LIMFNC3-E
; Define hardware end-of-travel limit #3 (normally defined
; as the home end-of-travel limit) as a "pause/resume" input.
COMEXR1
; Activating the pause/resume input will pause command and
; motion execution, de-activating the pause/resume input
; will resume command and motion execution.
MC1
; Set the axis to continuous motion profiling mode
A15
; Set acceleration to 15 units/sec/sec
AD5
; Set deceleration to 5 units/sec/sec
V4
; Set velocity to 4 revs/sec
GO1
; Initiate continuous motion
END
; End definition of program called "tsting"
; While this program is running and motion is in progress, you can send
; immediate LIMEN commands to simulate the function of the "pause/resume"
; input as follows:
;
1. Start the program by sending the RUN TSTING command to the drive.
;
The axis will start moving, using a continuous motion profile.
;
2. Send the !LIMEN.3=1 command to the drive. This disables the
;
"pause/resume" input but simulates its activation. Motion and
;
program execution will pause.
;
3. Send the !LIMEN.3=0 command to the drive. This disables the
;
"pause/resume" input but simulates its de-activation. Motion and
;
program execution will resume.
;
4. Send the !LIMEN.3=E command to the drive. This re-enables the
;
"pause/resume" input for normal operation with an external switch
;
or sensor.
;
5. To stop this experiment, send the !K command to the drive.
;
This "kills" program execution and motion.
