Extended capability F-7
F.1.5 Parameter table selection
A number of ‘parameter tables’ may be available for use during operation. The purpose of
these is to allow the easy selection of a number of common options/operations.
The parameters which may be selected are shown below:
 Dead path for laser encoders or reference offset from scale expansion origin
 Workpiece temperature sensor serial number
 Workpiece expansion coefficient
 Workpiece origin offset
 Workpiece origin type
The use of these switchable parameters allows such options as:
 Multiple machine home positions.
 Changing to an alternative machining zone.
 Use of multiple workpiece material sensors (for multiple machine zones or other
reasons).
 Changing of the material type (e.g. aluminium/steel)
The values for these parameters may be pre-configured at System Configurator level as
detailed in sections 4.2.4 and F.1.7.1, and then selected during operation by the machine
control or a simple switch.
The number of parameter tables available depends on how the system configurator has
programmed the RCU10s. A maximum of four parameter sets may be selected by use of
two hardware lines. The selection control is shown in the table below:
Table F.2 – Parameter table selection
Select parameter table PT select 1 PT select 2
1 HIGH HIGH
2 LOW HIGH
3 HIGH LOW
4 LOW LOW
(NOTE: If single parameter table operation is selected, there is not a requirement to
connect to the parameter table select lines.)
The procedure for use should be as follows:
1. Stop the machine/part program.
2. Change the selected parameter table (by use of the control lines).
3. Re-home the machine or axis. Once this is complete, the new parameter set will be
used and displayed in the software. This can be confirmed by looking at the RCU CS
status display screen to see which parameter table is shown as active.
