11.29.1. Upgrading the Spindle encoder on MASSO G2
Upgrading the MASSO G2 encoder inputs to take up frequency up to 20kHz
INFORMATION: This procedure is for only for the MASSO G2 as the G3 is capable of frequency
up to 60Khz
By default MASSO can take up to 8kHz encoder signals, to upgrade the inputs so that they can take
up to 20kHz please follow the below procedures.
To check the maximum frequency as per your machine spindle RPM and encoder PPR, please use
THIS CALCULATOR
If the calculated frequency is under 8Khz then you do not need to do the modification.
