TONiC readhead and ring compatibility
T20x1 readhead models are compatible with a range of REXM/REXT ring sizes. The optical
configuration is optimised for the following conditions:
Readhead model
T2001
T2011
T2021
Ensure readhead part number and REXM/ REXT size range compatibility at the time of ordering
and installation.
NOTE: Published accuracy specifications only apply when 2 readheads are used and the output
combined and blended using either a DSi or with the customers own electronics. For optimum
accuracy performance, the readheads should be mounted diametrically opposite each other so
that the optical centrelines are 180 ±1° apart.
TONiC Ti interface and DSi compatibility
When connecting a DSi the TONiC Ti interfaces must:
•
Be configured with line driven alarm outputs.
•
Have the same interpolation factor /resolution.
•
Have a clocked output option the same or lower than the connected DSi.
For details on readhead and interface configuration, refer to the TONiC
data sheet (Renishaw part no. L-9517-9337).
