The flash will effectively be invisible when passing the reference mark if the incremental signal is > 70%.
2
The alarm output will take the form of 3-state or line driven E signal depending on DSi configuration. The Ti interfaces connected to the DSi must be configured with the line driven alarm format.
• The alarm output is a momentary status only. It is only present while the fault condition remains.
• The alarm may result in axis position error, redatum to continue.

Some Ti interfaces do not output overspeed alarm. See the TONiC encoder system data sheet (Renishaw part no. L-9517-9337) for details of interface configuration. This can be downloaded from our website at
www.renishaw.com/tonicdownloads and is also available from your local Renishaw representative.
