•
The spindle interface is completely isolated by optocouplers. It can be used for automatic spindle
detection, if enabled.. To set a high level to one bit, a simple connection to the spindle GND is
made. An open contact equals low level. The direction of high/low active can be changed in the
form ‘digital inputs’.
•
The PTC input detects over-temperature of the spindle. A high resistor value at this pin of >600
Ohms causes the switching of digital output overtemp spindle and safety cut-out following the
programmed delay .
•
The Hall sensor input operates from input signal levels of +/- 1V within the common mode range
of 0..10V.
•
The 5V output can be used as a power suppl.
