System Control Board (SCBEVO-8)

The SCBEVO-8 is a 12 axis motion controller for use in Flying Probe Testers for PCBs.

The module is perfectly driven and controlled by the FourStars-ES ProbeStar Software.

The main function of the SCB are:

• Generation of pulse/direction signals for Servo-Amplifiers and Stepper-Motor-Controllers
• Handling of axis end- and reference-switches
• Test-Probe compression control

The  module contains:

• Power connector for single 24V DC supply
• Local voltage regulators
• Analog components (converters, amplifiers, etc. )
• High performance (Altera) FPGA for real time calculation of speed profiles and pulse generation
• FPGA integrated soft cores for smart data handling
• Interface to  Motor amplifiers
• Synchronization port to measuring devices
• USB-Interface to the controlling PC

Specification:

• Programmable parameter each axis:
  • stepsize (typ. 1 µm)
  • distance (steps)
  • max. speed forward/backward (steps/s)
  • acceleration forward/backward/z-detect (steps/s²)
  • jerk-suppression (steps/s³)
  • etc.
• Field upgradable firmware for CPU and FPGA
