DTC has 25 microsecond control loop Traditional PWM: • Control in short steps to avoid overshooting • Control loop time 1-3 ms because of modulator Frequency reference V/F ratio Modu-lator V AC f • Vector control: • Tachometer feedback required • Control loop time 1-3 ms because of modulator Speed control Torque control Modu-lator V AC f T • DTC principle: • Torque controlled by a single step • No risk of overshoot with fast 25 s control loop Speed control Torque control AC • Backlash appears in gearboxes and couplings. In backlash range motor may accelerate leading to backlash impact. Fast DTC control limits impact. • Mechanical resonances often appear due to elasticy of shafts and inertias of motor, gearbox and driven machine. Fast DTC attenuates the resonances.

DTC, Less stress to mechanics • Backlash appears in gearboxes and couplings. In backlash range motor may accelerate leading to backlash impact. Fast DTC control limits impact. • Mechanical resonances often appear due to elasticity of shafts and inertias of motor, gearbox and driven machine. Fast DTC attenuates the resonances.
DriveBus To overriding control Process Section Line Entry Section Drives system reduces energy consumption • Multidrive configuration • Common DC-Bus possible • Energy consumption is reduced • Compensating other loads is possible • Dimensioning of incoming sections and transformers or supply can be smaller • means lower investment
