10.7.2 Electrospindle states and corresponding sensor S1, S2, S5 outputs
STATE S1 S2 S5
Toolholder unlocked, collet open OFF ON OFF
Collet closed without toolholder OFF OFF ON
Tool-holder locked
and piston in safe position
ON OFF ON
The shaft of the electrospindle can only be rotated when the state is “Tool-holder
locked and piston in safe position”; if the outputs of S1 or S5 move to “OFF”, stop
the rotation of the shaft of the electrospindle.
10.7.3 S3 sensor “shaft idle” (optional)
Sensor S3 supplies two “ON” pulses and two “OFF” pulses at each rotation of the shaft, as shown
in the figure below.

For the electrical specifications see section 10.7.1 .
For the installation follow paragraph 12.1 and make sure to obtain the output illustrated in the
Image 10-1.
10.8 THERMAL ALARM
A normally closed switch is installed inside the motor. The switch opens if the motor reaches a
temperature likely to cause damage. Monitor the state of this switch via the wiring described in
section 9.11 and stop the electrospindle if the switch opens (OFF).
If the shaft stops while the tool is being pressed against the workpiece, this may
damage the spindle bearings. If an excessive amount of time is taken to move the
tool away from the workpiece and stop the rotation, there is a risk of burning-out
the stator.
