Marks on the encoder support
Mark on the encoder
Remove the rear cover 011, disconnect the encoder leads from the terminal block 310, remove the stirrups 067 and
extract the encoder. Remove the driving hub 035 and mount it on the new encoder.
Remount the encoder following the above instructions in reverse and connect it to the terminal blocks. Before finally
fixing the encoder set it as follows:
Lock the turret in any position, rotate the encoder slowly until the STROBE signal disappears (this can be checked
on the control system or with a voltmeter).
Mark the encoder and make a corresponding mark on its support. Slowly turn the encoder in opposite direction until
the STROBE signal again disappears, and mark the new position on the support.
This defines the region in which there is a STROBE signal. Slowly turn the encoder until the mark on the shaft is half
way between the two marks on the support.
Tighten the stirrups 067 and replace the rear cover.
