SPA3
The SPA3 is a servo power amplifier with enhancements for higher power and category 2 E-STOP.
SPA3 can be used with the current range of Renishaw controllers- The high power capability combined with a compact enclosure enables use of the SPA3 across a wide range of machines
- The SPA3 CMM amplifier has the capability to:
- power three axes of a CMM
- accept input signals from air pressure, crash detection and all axis inner and outer travel limit switches
- accept two uncommitted general purpose input signals and generate one uncommitted general purpose output signal
- provide a +24 V supply for use by the CMM switches
- support the MCUlite-2 joystick, and also support the MCU5, MCU5-2, MCU W and MCU W-2
- provide power output of up to 800 W continuous and 960 W for up to 1 second
- set the voltage of each axis independently allowing differing motor voltages to be used
- support dc motors in the range 12 V to 80 V and currents up to 10 A
- support encoder / tacho or linear encoders (torque mode) for velocity feedback
- provide category 2 E-STOP
