General wiring standards

To achieve reliable operation of the UCCFusion and the CMM host computer, the following should be observed:

• The PSU must be single fault tolerant, approved to EN60950-1 and must be connected to a supply incorporating a protective earth conductor. Earthing provisions and residual fault protection for the complete machine is the responsibility of the OEM or installer.
• The system must be PAT tested before the equipment is powered.
• All signal cables MUST be screened and all cable screens should be connected electrically to the cable connector’s metal shells.
• It is recommended that screens for motor cables should be connected to the shell on the UCCFusion end and connected to the motor housing at the CMM end.
• Signal cables such as tacho and scale cables should be connected to the UCCFusion and have a cable shield that runs to the machine but is left unconnected at the machine end.
• Motor screens should be connected to both the UCCFusion and the motor housing.
• Please refer to appropriate product installation guides when other Renishaw components (PH10, PI200 etc) are integrated into the system.
• All cables that are used to connect the UCCFusion to the CMM (that are not data cables) must have a minimum cross section of 0.3 sq. mm. (as specified in EN  60204-1 para.12.6.) UCCFusion has a maximum voltage of 80 Vdc and peak current is 10 amps. The actual peak current will be dependent on the size of the motor fitted and how hard it needs to be driven, so cable sizes need to be calculated by the system installer.
• All cable connectors should be secured to the UCCFusion by the connector jack screws.

The power input to the UCCFusion controller is via a 3W3 connector; refer to the Connector and signals section for more information.

UCCFusion power requirements

The UCCFusion controller requires 30 W of power to support the controller functions integrated into the unit; this must be factored into the power supply used.
