7.6 Safety functions
The below mentioned adjustments refer to settings made in SFU-Terminal
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 because of
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 because of
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 because of
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 because of
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.
