Renishaw PHC10-3 PLUS Probe Controller Installation Guide
Renishaw PHC10-3 PLUS probe controller installation guide, used to guide the installation, wiring, communication configuration, and troubleshooting of PH10 PLUS series electric probes. The equipment supports RS-232/USB dual communication interface, 24V DC power supply, 13 configuration switches, LED status diagnosis, and PICS interface, which can directly replace the old PHC10-2 and meet the high-precision motion control requirements of CMM coordinate measuring machines. It complies with FCC Class A, CE, and BS EN61010-1 standards.

PPOFF probe prohibition signal
3 0V public ground
5/9 Probe signal probe triggers output
7 PDAMP probe damping to reduce false triggering
Installation specifications
Size: 440 × 44 × 180 mm, weight 1.5kg
Installation method:
Desktop: equipped with rubber foot pads
Rack: 19 inch standard rack
Wiring requirements:
The internal resistance of the probe cable is ≤ 2.5 Ω
Continuous connection of shielding layer to reduce interference
Maintenance and troubleshooting
Maintenance: There are no user repairable parts, and any malfunctions need to be returned to the factory; Wipe the surface with a dry cloth
Typical faults:
The power light is not on: check the 24V power supply and emergency stop
Probe not moving: check wiring, baud rate, instruction set
Measurement error: loose probe, damping not closed
STOP trigger: overload, cable disconnection, USB hot plug
Key issues
Question: What is the main difference between the PHC10-3 PLUS and the old PHC10-2? What should be noted when upgrading? Answer: PHC10-3 PLUS has added USB communication, removed IEEE interface, and adjusted the layout of Rear interface, but the types are compatible; Simplify and consolidate the dip switches into one row. When upgrading, simply refer to the switch mapping table configuration, and after modification, press the reset button to directly plug and play the replacement.
Question: In what scenarios are the RS-232 and USB communication methods of PHC10-3 PLUS used? What are the restrictions? Answer: RS-232 is used for old CMM systems and requires baud rate/stop bit/instruction set settings; USB is used for new systems, plug and play, and faster. Restriction: Cannot access simultaneously; The maximum length of USB cable is 5 meters; USB disconnection triggers STOP; Switches 1-6 are invalid in USB mode.
Question: What are the functions of PPOFF and PDAMP signals in the PICS interface of PHC10-3 PLUS? In what scenario is it used? Answer: PPOFF is a probe power prohibition signal used to cut off and trigger the probe during indexing to avoid misoperation; PDAMP is a damping signal used to reduce the sensitivity of the CMM probe during rapid movement, prevent false triggering of vibration, and restore normal detection after reaching the position. Both work together to enhance measurement stability and safety.
