Technical Specification

Motion Control:

• 4 Pulse/direction or CW/CCW independent output for Step motor or servo motor control
• Able to realize cylinder and large breadth flat mark
• 1 MHz maximum step output rate for each axis
• Programmable LIMIT and ALARM protection
• Hardware capture signal : INDEX signal of each axis, HOME switch and Probe
• T curve velocity profile

Scanner Control:

• Voltage output for scanner control, which consists of 2 axes of linear interpolation and 2 axes of circular interpolation, and three-dimensional dynamic focus function (optional).
• 10us scanner control cycle
• Motion buffer can contain up to 10000 motion commands, providing a high real time control capacity
• Pause, stop and restore for the buffer motion
• 2 Modes of the mark on fly: mark on the fly without encoder feedback and mark on fly with or without encoder feedback.
• 3 Modes for the raster images scanning which can scan black-and-white image and grayscale image
• Field correction algorithm in board
• Have jump-laser-on function

Laser Control

• Able to control CO2 and YAG laser sources to give flexible FPK and STANDBY signals
• Supply one channel of high speed IO to control laser On/Off
• Supply laser On/Off delay, unit: 1us or 1/8us. Negative delay time allowed
• 3 laser power control methods: PWM, analog and programmable frequency output.
• Able to control laser power on/off directly

Input and Output:

• 16 dedicated opto-isolated inputs; home switch, positive and negative limit switch, amplifier fault signal for each axis
• 8 dedicated opto-isolated outputs: amplifier enable and amplifier reset signal for each axis
• 8 channels pulse output: pulse and dir or CW and CCW for each axis.
• 3 channels voltage outputs: 2 for scanner control, and 1 for laser power control. 16-bit D/A resolution and voltage scale: -10v~10v.
• 1 channel laser on/off signal output and 1 channel PWM output
