Renishaw RCU10, Installation And User Manual, Page: 64 / 202

System installation 4-15
Actuation Method <>: Select the method of activating workpiece expansion.
Data is stored locally in each RCU10 compensator.
Controller Signal: Workpiece thermal compensation is
activated by a signal through the J7 – Auxiliary I/O
connector from the machine control. Usually activated in
the control using M-codes (see Appendix F.1.4.1 for
details).
Axis Reference: Workpiece thermal compensation is
activated automatically at machine reference when the
RCU10 references, so workpiece thermal compensation
is effectively on permanently.
Structure Thermal Compensation
Temperature Sensor: Select the material temperature sensor to be used in the
compensation algorithm. Common for all parameter
tables in one RCU10 axis.
Thermal Compensation: Define the coefficient of thermal compensation required
in order to achieve the desired thermal structure
compensation. Common for all parameter tables in one
RCU10 axis.
4.2.5 Transmitting the configuration
Once the configuration has been completed, it is necessary to transmit it from the PC into
the RCU10 units. The RCU10 units will then store the configuration in non volatile
memory so it is retained even if the RCU10s are switched off.

To transmit the configuration to the RCU10 system, click on the Transmit button in the
button bar or select Transmit Configuration from the Configure menu. A dialogue will
appear for confirmation – this may take a few minutes on a large network.

You will then be given the option of saving the configuration to a file on your PC as a
back-up. Click Yes or No as appropriate to continue. It is recommended that a back
up copy of the configuration file is made at this stage.

RCU CS will respond with a message to advise of the system reset. Click OK and the
system will reset (a series of clicks may be heard from relays inside the RCU10s).

The RCU Connection Wizard will be displayed to re-establish communications with
the network. This will show all axes in configuration mode. Click OK to continue
operating with the system.
Changing operating modes
Once the configuration has been completed and transmitted to the RCU10(s), the system
may be switched into compensation mode (normal operational state).
This may be done by one of two methods:
