8.4.2 Temperatures
Which temperatures are evaluated and displayed depends on the number and the mounting
location (e.g. for sensor S6, bearing temperature front) of the sensors installed in the spindle.
The motor temperature is not displayed when the temperature sensor sensor type parameter
p0601 = 0 or 1.
Note
Temperature limits
The limit values displayed here refer to the spindle monitoring and have no effect on the drive
parameter values set in the drive that apply for the shutdown response of the spindle. The
temperature limit values are preset in the SMI24 and cannot be changed in this window. If
necessary, you must adapt the shutdown limit values for the drive.
Up to three temperatures can be evaluated:
