Application
example(s)
With the variable signal function the machine tool manufacturer can monitor one additional
threshold value for specific applications for each axis/spindle and evaluate the result in the PLC
user program.
Example:
The interface signal:
DB31, ... DBX94.7 (variable signaling function)
should be set to a 1 if the motor torque exceeds 50 % of the rated torque.
