6.8.5 ES332 electrospindle sensors
The electrospindle ES332 is fitted with inductive sensors for monitoring its state and a "thermal
alarm" for protecting the electric windings.
6.8.6 ES370 electrospindle sensors
The ES370 electrospindle has a "thermal alarm" to protect the electric windings and inductive
sensors can be fitted (optional) to monitor the correct coupling of the toolholder cone.
6.8.7 Technical characteristics of inductive sensors
NAME SIGNAL INFORMATION
S1 Tool holder cone coupled
S2 Collet open - Tool uncoupled
S1+S4 HSK cone locked in the correct position
S5 Cylinder in place
Thermal Alarm
Motor overheated:
stop the electrospindle!
NAME SIGNAL INFORMATION
S1 Tool holder cone coupled
S4 HSK cone coupled and in the correct position
Thermal Alarm
Motor overheated:
stop the electrospindle!
In the case of electrospindle models without sensors it is the customer's
responsibility to monitor its state, with particular attention to the toolholder
coupling.
An imprecise coupling may constitute a serious risk to the operator.
Proximity PNP type Normally Open (N.O.)
Power supply voltage 10 ÷ 30 V (DC)
