    HEIDENHAIN ROD 426.0010-128 - what PPR?

    Hi Folks,

    I have two heidenhain incremental encoders. Theirs name plates say ROD 426.0010 - 128. Id. Nr. 250 048 57.
    I found Heidenhain datasheet for the whole encoders family. ROD 426 is described on page 28 but there is no info how to check how many pulses per revlution my encoder produce! I can't check it electrically by hooking it up to some drive etc...

    Do you guys have some more detailed datasheet for ROD 426 series Heidenhain encoders??

    Mine are reasonably self explanatory, i might have made the classic mistake but have assumed they are 1000's.

    initially i thought mine encoders are 128 ppr but there are no 128ppr resolution listed under ROD426 encoders in Heidenhain catalogue...
