CNC Bender LiteControl 10.0.6.0
Contents |
This is change to an older version of CNC Bender LiteControl. It is intended to update customers with older 800 x 600 screen operator stations.
New: BUILT IN - SEAM DETECT LOGIC
New seam detect logic uses a secondary process list that runs in parallel to the main process list in order to detect a seam.
The diagram on the right shows the main process in the orange box on the left. This is the actual bend program process.
The box on the right is the secondary process called SEAM_DETECT. It causes the rotate axes to spin until the seam is located and the seam detect input is ACTIVE. (This process can be modified for your application.)
When the seam is detected, then the SEAM_DETECT process STOPS RUNNING, causing the ROTATION JOG to also STOP.
Then the main process detects that the seam detect input is ACTIVE and moves to the next step (See "3" in the orange box).
New: BUILT IN - SEAM DETECT OPTION
The new feature can be switched on with the Seam Detect option in the PreBend option:
Enable this option to include seam detection logic in the process list.
If enabled, the new commands for seam detection are added to the processlist between the chuck close and the run button logic. This is a sample of what is inserted. (What you see here represents the commands for STEPS 1 and 2 in the orange box in the image above.)
The new "seam_detect.cncprocesslist" is a secondary multitasking processlist that is configurable to work with the application.
NEW: INTERNAL COMMANDS [direct_axis_jog] and [direct_axis_jog_halt]
[direct_axis_jog]
This processlist internal command will allow the process to direct-jog and axis as if a user had pressed a jog button. Configure the command by including parameters like this:
[direct_axis_jog] servo_controller_module_1, 2, 1
Each parameter is separated by commas and are defined as:
- PARAMETER 1: The first parameter is the name of the module
- PARAMETER 2: The second parameter is the axis of the module (1 or 2)
- PARAMETER 3: The third parameter indicates direction. "1" means positive jog. "-1" means negative jog.
[direct_axis_jog_halt]
This processlist command uses no parameters. It halts all jog motion.
Sample of How Used
These commands can be used to move, for example, the rotate axis until a seam is detected by a device which actives an input. Examine the "seam_detect" processlist to see how this works:
[direct_axis_jog] servo_controller_module_1, 2, 1 [if] and, input=Input_SeamDetect_End // Seam detected - Disable the rotate jog now [direct_axis_jog_halt] [SECONDARY_PROCLIST] seam_detect, disable [end]
The jog command rotates the 2nd axis of the first servo module in the positive direction. This is the rotate axis. The motion continues until the seam detect input activates. At that point the jog is halted with the second command, and the secondary processlist disables itself.
