Laser Control Note
To be able to control the laser using the software Laser Control window or Trouble Reset button
in the Laser Status line the laser must be in RS-485 mode. If the laser is in “Panel Mode,”
“External Mode,” or “Ext + RS-485” the buttons in the Laser Monitor screen will not work.
If “Panel Mode” appears on the Branch Shutter screen of the laser:
Reconnect the RS485 using the software button in the Laser Control window
If “External Mode” appears on the laser Branch Shutter screen:
Use the MDI screen to send a M52 to release external control
Reconnect the RS485 using the software button in the Laser Control window
If “Ex RS485” appears on the laser Branch Shutter screen:
Use the MDI screen to send a M52 to release external control.
Note that modification of laser schedules at the laser can only be done with laser in Pendant
Control Mode. External and ERS485 lock out access to laser schedule programming.
This issue can be avoided by including an M53 s1 (removes RS485 control) before the first laser
command and an M52 after the last laser command in every program as standard programming
practice. The RESET button included on your pendant will also set the system in Pendant
Control Mode.
