I2t is an overload temperature protection algorithm.
Elmo uses the I2t protection method to prevent motor winding and insulation damage caused by high motor temperature due to motor excessive work.
The I2t algorithm evaluates the motor dissipating heat without any sensor. When the evaluated temperature exceeds the maximum, the motor current is lowered to continuous current and the peak current is blocked until the I2t Protection algorithm unblocks it.
The I2t principal algorithm calculation is as follows:
