F-2 Extended capability
F.1 Extended RCU10 system capability
F.1.1 Extended system capability
The RCU10 system includes a number of features that enable the basic performance of
the system (detailed in section 1) to be extended. These optional features include:
 Extended system status monitoring capability through three output lines (per axis).
 Ability to control the material compensation feature through a combination of input
lines to the RCU10 compensator.
 Parameter tables that enable the user to have up to four different sets of
compensation parameters. These parameter tables are selected through two input
lines to the RCU10 system.
Full details of each of these features are provided in this appendix.
F.1.2 Extended system status monitoring
The RCU10 is capable of two different modes of operation with respect to error-handling.
In the simple mode, all errors are indicated by monitoring the Error output line.
There is also an extended mode of error-handling (termed Advanced) which allows a
greater level of monitoring of the RCU10 status by the machine control. When the
extended mode is selected, two lines are available in addition to the standard
Error line;
these are Warning and Suspend .
WARNING : When the Error line signal is asserted on any axis, the machine
control MUST deactivate the entire machine.
F.1.2.1 Extended status monitoring
Extended error line outputs
When the system is configured with extended error line operation enabled, three levels of
error are available to the machine control. The advantage of this extended error handling
is that the machine will not be ‘shut-down’ by problems of lesser importance, but they
may be indicated in a manner that allows planned maintenance. The three levels are as
follows:
Warning Low-level errors which don’t affect system accuracy but indicate that
maintenance is required.
Suspend Medium-level errors which may affect the accuracy or operation of the machine.
Processes/part machining should not be allowed until this error has cleared.
