Renishaw RCU10, Installation And User Manual, Page: 60 / 202

System installation 4-11
Tristate On Error: The output quadrature signal may be configured to transfer into a
high impedance (undriven differential) when an error occurs on the
RCU10. Ensure that the controller is capable of recognising this if it
is enabled. This selection is not available if analogue output format is
selected.
See configuration warning 4 on page 4-12.
Controller Logic: Selects the voltage level used on the Auxiliary I/O port, between 5 V
and 24 V. This must be selected to match the link settings on the
PULL pin of the Auxiliary I/O connector (refer to section 2.3.2 for
details).
Limits
Maximum Following Sets the error limit for the maximum error that can occur
Error (Accuracy): between the input and output counts of the RCU10. User-
selectable from 11 fixed settings ranging from 1 mm to 1

m.
Recovery Injection Sets an injection rate that is used to re-inject movement when
Rate: certain functions are operated (e.g. deactivating workpiece
compensation at distance, compensation buffering).
Misc
Inhibit Compensation When selected, the RCU10 will only power up into
Mode: configuration mode. When deselected, the RCU10 will
automatically power up into compensation mode.
The factory default setting is on, and should be changed
only after final checking of each axis configuration. This
setting should be the same for all units.
Termination Enabled: On a multi-axis system, the physical end units in the system must
have this option enabled to prevent "ringing" on the high-speed
serial link transmission lines. The software will allow either 0 or 2
to be selected in a system. This function should be configured as
shown in the table below (the table assumes that the RCU10
units have been configured and installed sequentially).
NOTE : Do not enable internal termination if your system was
supplied with external high speed link terminators.
