HEIDENHAIN iTNC 530 HSCI - Limit Values; Motor Overload with I2 T Monitoring

912 HEIDENHAIN Technical Manual iTNC 530 HSCI
Limit values The limit values for the I
2
t function (measure of the permissible temperature
inside the device [%]) are managed by the control's NC and are structured as
follows:
 Value exceeds 100%: An axis-specific I
2
t early warning is sent to the PLC
(for evaluation and possible countermeasures such as reduction of the feed
rate with error message by PLC program with the aid of PLC Module 9160).
If the value does not exceed 110% and falls below 90%, the axis-specific
early warning is reset.
 110%: An NC stop is triggered and the drives are switched off.

Note
In the oscilloscope you can display the current value of the I
2
t monitoring
of the motor and power module, as well as the current load of the drive.
