Dual Signal interfaces
– DSi
|
|
For use with RESM, REST, REXM or REXT rings.
|
|
Note: Part numbers beginning A-XXXX-XXXX are not valid for
TONiC DSi units.
|
|
The nomenclature should be used
when ordering DSi units (For example DSI-QTL01).
|
|
Some variants are not yet included on the ordering system.
Please contact EPD to add variants to the system.
|
|
Note: PLEASE SELECT THE SAME CLOCK FREQUENCY DSi AS THE TONiC
INTERFACES USED.
|
|
Note: Partial-rotation DSi has not been tested with RGS scale

TONiC Dual Signal interfaces – DSi
Renishaw’s
DSi (Dual Signal interface) is now available with its TONiC™ family of
incremental optical encoders, bringing even higher accuracy to rotary axes and
giving customers a selectable reference mark position via the company’s propoZ™
technology.
Using two
readheads on an angle encoder improves the accuracy and repeatability of the
motion system by eliminating eccentricity, bearing wander and all ‘odd’ error
harmonics. When used with Renishaw’s REXM ring encoders, a total installed
accuracy of better than ±1 arc second is achieved. The combined TONiC DSi
system makes adding a second readhead easy by taking care of the combination of
incremental channels and reference mark processing.
Renishaw’s
patented propoZ technology allows a customer to easily select reference output
position with the press of a button. Furthermore, the propoZ output position is
angularly repeatable, regardless of bearing wander or power cycling.
The TONiC
DSi system can be used with Renishaw’s RESM encoder rings in a range of standard
diameters from 52 mm to 550 mm (with even larger diameters and custom sizes
available on request), or with ultra-high accuracy REXM rings for the most
demanding precision rotary motion applications.
As with all
Renishaw encoders, the TONiC DSi system is backed by a truly responsive global
sales and support network. Furthermore the TONiC and DSi products satisfy the
highest environmental standards, with both WEEE and RoHS compliance.
