7.7 Safety Functions
The menus described in the following refer to the SFU-Terminal software.
Automatic shutdown
•
The following incidents lead to a controlled braking and decelerating to standstill of the spindle
according to its acceleration times defined in the spindle characteristic.
✓
Stop due to excess temperature at the spindle , in case this function is activated and if its
corresponding delay time is exceeded, which can be adjusted in the menu "Delays..excess temperature
spindle"
In the "Spindle characteristic" this function can be activated with the Check-Button Temp. sensor and
according delay time can be setup in the menu "Delays"
✓
Stop due to excess temperature of the converter , in case this function is activated and if its
corresponding delay time is exceeded, which can be adjusted in the menu "Delays..excess temperature
converter"
✓
Stop due to overload and if its corresponding delay time is exceeded, which can be adjusted in the
menu "Delays..overload" The limit values for overload are determined in the spindle characteristic.
Generally for S1 operation the current value will be 100% and overload condition is about 10% more
and for S6 operation about 30% more. The default delay value is 20sec.
✓
Immediate stop because of exceeding the maximum admissible current of the converter
✓
Emergency Stop because of a valid signal at input Emergency Stop setup in menu "digital inputs"
The following incidents lead to a shut off of the output stage. the spindle will not be braked and will
decelerated by its internal losses and friction. This can take quite a long time until standstill depending
on its rotary mass. For a safe detection of standstill a speed sensor would be recommended.
✓
Stop due to short circuit at spindle connector. The value is defined by internal limits.
✓
Stop because of signal at digital input Power Stage Off setup in menu "digital inputs"
A restart can only be achieved with a systematic Stop/Start-Sequence or with a valid signal at the input
"Error Reset". This can be setup in the menu "digital inputs" the power stage will be activated again
after 4 sec.
