SPA3-2

SPA3-2

The SPA3-2 is a 3-axis dc servo power amplifier and is a drop-in replacement for the SPA3. The SPA3-2 is compatible with the UCC controller range and the MCUlite-2, MCU5-2 and MCU W-2 joysticks.

This system can operate on the majority of CMM structures without the requirement for changing motors.

Features

The SPA3-2 has the following improvements over the SPA3:

  • The primary advantage of the SPA3-2 is the ample machine I/O: six inputs and seven outputs as well as six I/O ports which are configurable to be either inputs or outputs
  • Adjustable power supply voltage to readheads and motor encoders
  • Support for absolute BiSS readheads
  • Support for up to four axes of position feedback for dual Y scale machines

Operating specification

  • Three axis dc servo motor drive:
    • Independent axis voltage control of 12 V to 80 V
    • Independent axis current limits up to 9.5 A peak
    • Simulated linear power amplifier. Drive outputs are free from switching edges, eliminating noise from drive PWM, improving repeatability and reducing emissions
  • Axis scale and motor encoder power supply: 5.25 V to 6.75 V, 0.5 A maximum (each)
  • +24 V 1 A power supply for CMM solenoids, solid state switches, machine user specific hardware
  • Digital input signals from air pressure, crash detection, all axis inner and outer travel limits and six user specific inputs
  • Digital output signals to control machine air, axis brakes and seven user specific outputs
  • Six configurable digital pins which can be independently configured to be either input or output
