9.15 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.,
TEMP.MOT. STOP ADJUSTMENTS list.
A linear reduction is performed for temperatures between MAX. MOTOR TEMP.
and TEMP. MOT. STOP . It acts scaling down the torque profile (see paragraph
9.15) by a percentage from 100% to 50%.
When motor temperature reaches TEMP. MOT. STOP, current cutback is fixed to
50%.
Torque reduction for motor thermal protection.
 Cutback is valid only during motoring, instead during braking the 100% of the
maximum current is always available regardless the motor temperature.
 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 50% is applied.
