Hardware integration
- The PH20 system is only available with the UCC T5 controller
- SPA3 is a servo power amplifier used to power the CMM
- MCUlite-2 / MCU5-2 / MCU W-2 are the multi-function hand control units available for use with the PH20 system
Head axis range
The PH20 head has two rotary axes (A and B) and is normally mounted on the CMM quill to create a 5-axis measuring system.
The PH20 head's B-axis is mounted on the CMM quill and can rotate continuously in both directions.
The A-axis, which is orthogonal to the B-axis, has ±115° of travel.
The head can only be mounted in the vertical orientation shown below.
