(*) WEG motors that can be used with the Optimal Flux function: Nema Premium Efficiency, Nema High Efficiency, IEC Premium Efficiency, IEC Top Premium Efficiency and "Alto Rendimento Plus". When this function is activating, the motor flux is controlled in a way to reduce their electric losses on slow speeds.
Page 126: Optimal Braking
Vector Control NOTE! For torque control in the sensorless vector mode (P0202 = 3), observe: - The torque limits (P0169/P0170) must be higher than 30 % to assure the motor starting. After the start and with the motor rotating above 3 Hz, they can be reduced, if necessary, to values below 30 %. - For torque control applications with frequencies until to 0 Hz, use the vector with encoder control mode (P0202 = 4).
Page 127 Vector Control The Optimal Braking makes it possible braking the motor with a higher torque than the one obtained with traditional methods, as for instance, the braking by the injection of direct current (DC braking). In the DC braking case, only the losses in the motor rotor are used to dissipate the energy stored as the mechanic load inertia, rejecting the total friction losses.
