IU80 interpolator unit
A free-standing interface for the SP80(H)
- Required for installations where the UCC2 daughtercard is not used
- Connected to the probe by the machine cable, the output of the IU80 is then transferred either to the CC6, or alternatively to an OEM controller via a Renishaw supplied unterminated cable
|Height||44 mm (1U)|
The IU80 divides the 4 micron periodic signals produced by the SP80 (H) by a factor of 200. This gives a system resolution of 20 nm for each probe axis.
Error signal generation
The IU80 monitors the signals received from the SP80 (H) probe to ensure that each axis readhead is functional. In the event of probe cable damage or unreliable probe signals, an error signal is latched and provides an output via pin 4 of the 26-way connector. A red LED on the IU80 front panel also indicates the same error conditions however, the different errors can be distinguished by an operator looking at the different LED states as detailed in the probe LED summary section below. The latch can be reset by either pressing the button on the front panel or applying logic ‘1' to pin 3 of the 26-way connector.
SP80 LED control
The SP80(H) probe has a tri-colour LED which can be controlled by the user to act as a visual aid for measurement applications.
The LED can be set to red, green or orange depending on the following inputs to pins 9 and 10 of the 26 way ‘D' plug.
(Logic ‘1' = +3 V to +5 V Logic ‘0' = <0.8 V)
Probe present signal
The IU80 will detect if an SP80(H) probe is connected.
If a probe is present, error signals will be enabled and pin 8 of the 26-way plug will be logic ‘0'.
If a probe is not present, error signals will be disabled and pin 8 of the 26-way ouput connector will be logic ‘1'.
IU80 front panel
The front panel of the IU80 has two LED indicators and a reset button.
The green 'POWER ON' LED is illuminated when power is applied to the IU80.
The red 'PROBE ERROR' LED is illuminated if an error has been detected.
The reset button, when pressed, will clear the error condition.
Probe error LED summary
|PROBE EROR LED status||Indication|
|Permanently off||No error|
|Permanently on||Probe signal integrity compromised|
|Flashing||Cable break detected|
