Ovo je kavezni trofazni motor upravlan preko acs600 I taj acs mjenja napon I frekvenciju da bi pri odredenim okretajima dobio odgovarajucu snagu I moment da bi izvrsio rad koji je potreban.
ACS 600 is a new generation AC drive that achieves the ultimate in AC motor control performance. The first AC
drive to utilize Direct Torque Control (DTC), the ACS 600 accurately controls the speed and torque of any standard
squirrel cage motor
Direct Torque Control (DTC) is a unique motor control method for AC Drives. The inverter switching directly
controls the motor flux and torque.
The measured motor current and voltage are inputs to an adaptive motor model which produces an exact actual
value of torque and flux every 25 microseconds. Motor torque and flux comparators compare actual values to the
reference values produced by the torque and flux reference controllers. Depending on the outputs from the twolevel
controllers, the optimum pulse selector directly determines the optimum inverter switch positions.
. Full Torque at Zero Speed
The motor run by the ACS 600 can develop motor nominal torque at zero speed without any pulse encoder or
tachometer feedback. The feature is essential in several applications including elevators, lifts, hoists, and
extruders. However, if long-term operation at zero speed is required, a pulse encoder may be necessary.
. DC Magnetizing
When DC Magnetizing is activated the ACS 600 automatically magnetizes the motor before the start. This feature
guarantees the highest possible breakaway torque, even 200 % of motor nominal torque. By adjusting the
premagnetizing time, it is possible to fix the motor start with a mechanical brake release, for example. The
Automatic Start feature and DC Magnetizing cannot be activated at the same time.
. Automatic Start
The Automatic Start feature of the ACS 600 outperforms the flying start and ramp start features normally found in
AC drives. Because ACS 600 can detect the state of the motor within a few milliseconds, starting is immediate
under all conditions. There is no restart delay. For example, the starting of turbining pumps or windmilling fans is
easy.
. DC Hold
By activating the motor DC Hold feature it is possible to lock the rotor at zero speed. When both the reference and
the motor speed drop below the preset DC hold speed, the ACS 600 stops and starts to inject DC into the motor.
When the reference speed again rises above the DC hold speed, the normal ACS 600 operation resumes.
