Calibration
The system must be calibrated if the installation is disturbed or if the DSi has been
moved to a different axis.
1) Install the TONiC readheads as detailed in the TONiC REXM encoder system
installation guide (M-9653-9428).
2) With the power off, connect the TONiC systems and output cable
to the DSi. NOTE: The TONiC interfaces connected to the DSi
must have identical part numbers.
3) Calibrate each TONiC system separately as detailed in the
TONiC REXM encoder system installation guide (M-9653-9428).
4) Check the relevant head orientation switch position on the
!
back of the DSi.
5) Use a small hex-key (or other suitable implement) to press and hold the
recessed propoZ button on the front of the DSi as the power is switched on.
The LED on the DSi will show red. Now release the button and the LED will
show orange, then start to flash green. The K output will be 'low'.
6) For complete rotation: Rotate the axis in one direction until the LED stops
flashing (the K output will go 'high'). NOTE: The axis may need up to two full
rotations to achieve this. The DSi has now memorised the number of counts
per revolution and determined the factory default propoZ position.
For partial arc rotation: Ensure the ring is installed so the reference marks are
positioned correctly (Refer to the REXM/REXT Installation guide M-9653-9248).
Rotate the axis in both directions to its maximum travel until the LED stops
flashing (the K output will go 'high'). The factory default propoZ position has
now been determined.
NOTE: For optimum system accuracy and performance at higher speeds
ensure that the AGC is swtiched off on the interfaces.
Initialisation
( Required at each power-up and after an error)
1) The axis must be rotated in one direction
(either clockwise or anti-clockwise)
TM
until the physical IN-TRAC feature on the ring passes
both readheads. The LED will then go solid green and
the K output will go 'high'.
2) Initialisation is now complete.
The propoZ reference (index) output will be given when
the axis next passes the propoZ output position.
If an alarm occurs, DSi will automatically re-enter initialisation
mode when the alarm condition is removed.
