9.14 Motor thermal protection
The controller performs a thermal protection of the driven motor by monitoring its
temperature and applying a linear cutback to the maximum current when it
becomes excessive.
Thermal protection can be tuned setting parameters MAX. MOTOR TEMP.,
STOP MOTOR TEMP. and MOT.T. T.CUTBACK in the ADJUSTMENTS list.
A linear reduction is performed for temperatures between MAX. MOTOR TEMP.
and STOP MOTOR TEMP. . It acts scaling down the torque profile (see
paragraph 9.12) by a percentage from 100% to MOT.T. T.CUTBACK.
When motor temperature reaches STOP MOTOR TEMP., current cutback is fixed
to the percentage set in parameter MOT.T. T.CUTBACK.
4
Cutback is valid only during motoring, instead during braking the 100% of the
maximum current is always available regardless the motor temperature.
4
If the signal from the motor thermal sensor is out of range (for example due to a
problem related to the wiring), a cutback equal to parameter MOT.T. T.CUTBACK
is applied.
