Pump-motor control application
Inverter in injection moulding machines to control the motor of the pump
Inverter type: V/f DFNT without feedback
Characteristics:
- Overload 200% for 2 sec. for high breakaway torque
- Min. revolution speed always present
- V/f characteristic with the possibility of motor discharge (deflussare) to reach revolution speed above 50 Hz
- Auto tuning to any motor type
- Revolution linearity at low frequencies
- Possibility to set PWM
- PTC thermal switch control
- Temperature reading
