Section 3 Initial Setup

COM 4 depending on how many serial ports and serial devices you have, such as a modem. Once you determine the serial port, choose it from the Serial Port pull-down menu.

3.The Baud Rate is the speed at which the LC communicates across the serial port with the Controller. It is measured in bits per second. This is typically set at 38,400. For older PC’s exhibiting serial communications problems, set this to a lower speed. For most applications, LC will perform the same at baud rates of 19,200, 38,400 and 57,600. If you change this setting, you must reset the baud rate on the Controller by going Offline and Online from the Controller menu. If there are communication problems, you must turn the Controller off and on before going back online.

4.The Buffer Time is used to prevent system events (such as screen updates) from affecting motor movement on the machine tool. The larger the Buffer Time, the less effect system events have on motor movement. The smaller the Buffer Time, the more responsive the machine tool is to mouse clicks and keyboard commands. In most cases, the lag-time between the PC and the motor movement is imperceptible. The value can range from 0.01 to 1.0 seconds. Slower computers may require a higher value. If you want to change this setting, enter a new value in the Buffer Time text box.

5.The Start Delay allows the screen to fully update after the Start button or Jog button is selected and before your machine tool begins moving. There are separate values for Jog moves and G-Code or Point moves. Slower computers may require a higher value. If you want to change these settings, enter a new value in the appropriate text box.

6.The Coordinate Update value determines how often the coordinates are updated in the Tool Position Box while the tool is moving. There are separate values for Jog moves and G-Code or Point moves. Higher values may increase performance on slower computers. If you want to change these settings, enter a new value in the text box. Note that coordinates are always updated at the end of every move.

7.The size of the Program Listing Box affects system performance during a continuous run. To see the entire Program Listing Box during a continuous run, select the Show Program Listing Box radio button. For better performance, select the Show Current G-Code Line Only radio button. This is especially important when you’re running programs with a large number of very short moves.

8.LC Series can easily be configured for the type of machine that you are running. Choose either Mill or Lathe from the Type pull-down menu. If you are using a machine with CNC control on the X and Y axes only, remove the check from the Z Axis check box.

9.The Controller model you have affects the way in which the limit switches should be wired. Choose the appropriate model number from the pull-down menu. If you have Model 401A the limit switches should be wired normally closed. If you have Model 401 the limit switches should be wired normally open.
