6.8.8 Electrospindle states and corresponding outputs from
inductive sensors
ES327 and ES330 “air”
ES330 “liquid”
The sensor “ON” condition corresponds to an output equal to the power supply
voltage. The “OFF” condition corresponds to a 0 V output..

OFF OFF
The electrospindle shaft can only rotate in the "tool holder cone coupled" state;
if S1 output changes to “OFF”, stop the rotation of the electrospindle shaft.
