3240 Motor Control Board
laser repair, esi laser, gsi laser
The model 3240 indexer (also referred to as the “T80 board”; see Figure 3-12) is an 8-channel, optically-isolated, general purpose stepper motor controller that generates step and direction commands for the driver amplifiers and monitors signals from Home and End-of-Travel sensors. The 3240 is used to control Zaxis height and beam spot size (i.e., focus and zoom lens position) among other functions. The 3240 provides a programmable output that is configured on the driver board to provide input to the amplifiers. An additional input signal to the 3240 can be connected on the driver board to one of a number of possible physical sources to detect possible error conditions.
