7.8.2 Technical characteristics of the inductive sensors
7.8.3 Electrospindle conditions and corresponding outputs
of the inductive sensors
The sensor “ON” condition corresponds to an output equal to the power supply voltage. The
“OFF” condition corresponds to a 0V output.
The electrospindle shaft can only rotate in the “tool-holder cone correctly locked”
condition, and if the piston is fully backward (S5 ON, if present). If outputs S1 / S1+S4
(HSK versions only) or S5 (if present) change to “OFF”, stop the rotation of the
electrospindle shaft.
