Renishaw RCU10, Installation And User Manual, Page: 141 / 202

E-2 Commissioning tests
E.1 System performance testing
There are a number of calibration tests that may be performed on the installed RCU10
compensation system. Not all tests will be required, depending upon the configuration of
the installation and the functions being used. The majority of tests are designed to test the
operation of workpiece thermal compensation.
NOTE: These tests are designed to confirm the operation and accuracy of the encoder
and RCU10 quadrature compensation system, NOT the machine as a whole.
E.1.1 Prerequisites
The following equipment is required to carry out the tests:

Desktop or laptop PC installed with LaserXL and RCU CS software.

Renishaw XL-80 calibration laser. (If a gantry axis with two independent scales is
being measured, then two XL-80s are desirable to obtain simultaneous
measurements, but not essential.)

Renishaw linear optics kit. (If measuring an axis over 30 m in length, then the long-
range linear optics kit is required.)

Renishaw XC-80 environmental compensation unit.

Renishaw XC-80 air temperature sensor.

Renishaw XC-80 material temperature sensor.
Each set of tests should be conducted for each axis before moving on to the next axis.
This will allow multiple tests to be conducted for one optical set-up. Before commencing
testing, ensure that the following has been carried out:

Connect an XC-80 unit to the XL-80 to compensate for measurement errors due to
environmental effects.

Connect the XC-80 air temperature sensor to the XC-80 system. This must be
mounted close to the air sensor for the axis under test. (If tape/glass scale encoders
are being used, then the air sensor must be placed close to the material
temperature sensor being used to provide encoder compensation for the axis under
test.)

Connect the XC-80 material temperature sensor to the XC-80 system. This must be
mounted close to the material temperature sensor being used for workpiece thermal
compensation on the axis under test.

Connect the XL-80/XC-80 system to a desktop or laptop PC with LaserXL software
installed.

Ensure that any error compensation is disabled in the machine controller.
