Product bulletin: PBC-1112 - SPA2 product replacement - SPA2-2 product launch (pdf)

As part of Renishaw’s continuous product improvement program, we have reviewed the design of the SPA2 Servo Power Amplifier system and a new Mk.2 version, SPA2-2, is now available. The new SPA2-2 has been redesigned to simplify both the customer configuration process and in-house manufacturing. As part of these changes we have now incorporated motor encoder functionality as standard onto the main PCB. This means that for CMMs fitted with rotary encoders, for motor velocity control, a separate encoder plug in card is no longer required. All the motor type option cards and the additional axis card have also been updated to be compatible with the new enclosure design. The additional axis card is now fitted in the opposite side of the unit over the power supply.
