Renishaw RCU10, Installation And User Manual, Page: 65 / 202

4-16 System installation

Change the mode manually using the Mode button in the button bar. This is a
toggle button and will always try to change mode, i.e. if in compensation mode it will
change into configuration mode and vice versa.

Remove and then restore power to the system. At power on, the RCU10 will always
try to enter compensation mode.
NOTES: The RCU10 will not change into compensation mode if the Inhibit
compensation mode setting is not cleared in the configuration (this applies to
all RCU10 units in a network) or any critical errors are detected at power up.
Any data that has been entered into the PC but not transmitted to the RCU10
will be lost if proceeding with a mode change.
The mode shown on the status bar is not updated until the connection wizard
is closed.
Compensation algorithms and parameter table selections will not be
implemented until after the system has been referenced.
WARNING: The RCU10 system may be returned to configuration mode at any
time if it is required to make changes to the parameters or configuration. The
RCU10 does not provide valid feedback signals when in configuration mode. For safety
reasons it is important that the machine or axis is safely disabled before proceeding with
a mode change. The RCU10(s) asserts the RS422 error line to ensure that this occurs.
4.3 Configuration validation
Before proceeding to controller integration, the validity of the RCU10 system
configuration needs to be verified. Now that the system is in compensation mode, this is
simply a case of observing that the display on the front of each RCU10 unit shows RDY.
If this is the case, then the next stage of installation is controller integration as described
in section 5 of this manual.
If ERR is displayed on any of the RCU10 units, then select the Diagnostics button on the
RCU CS button bar. The system status screen will be displayed (as shown in Figure 4.6),
with the axis or axes which are displaying error having either the Comms or Status
indicator RED.
