This field determines how long the motor can operate while peak rms current is flowing in its windings. This time should be determined by motor manufacturer.

This is an index of motor's "over-heat" status. It changes between 0 and 250. At 0%, the motor is not overheated. When this value reaches 100% the motor is at its maximum allowed over the heated conditions, and if motor I2t protection is enabled, the maximum rms current will be limited. This limitation will be removed when the percentage drops to 50% or less.

This object value is updated with the motor heat index only when motor i2t protection is enabled i.e. when 0x200a:01 Enabled is selected as Motor i2t and combined stall protection - Current Limit or Motor i2t and combined stall Protection - Error Reaction. Stall protection doesn't update this index.

As long as it is 0, i2t or stall protection is not enforcing any limit on maximum rms current of your motor. Once it is 1 it means that i2t or stall protection is limiting the "maximum rms currents" of your motor. I2t protection limits the current to motor rated current. Stall protection limits the current either to the motor rated value or FET rated value depending on which one is smaller. If only FET Stall Protection is enabled than current is limited to the rated FET current value.
