Spindle RPM Encoder

An incremental encoder is used to monitor spindle RPM and also for synchronised threading on lathes

 

Pin No. Description Type
Pin 1 Signal A Opto input (5 to 24v)
Pin 2 Signal B Opto input (5 to 24v)
Pin 3 Signal Z – Index Opto input (5 to 24v)

 

 

 

 

INFORMATION:

  1. Recommended maximum encoder PPR is 100, PPR above this will reduce the maximum RPM range.
  2. All inputs can be easily inverted by selecting the input in the INPUTS list and pressing the space-bar key on the keyboard to invert the input signal.
