This Scalar Control (V/F control) special AC drive (vvvf drive, vsd) for injection molding machine is AC-DC-AC converter, dediciated for injection moulding machine, has the features below:
 
1.Central control module based on DSP, realizes high-speed & high performance control.

2.Control mode: Scalar Control (V/F control), Scalar Control (V/F)+PG control (optional).

3.3 space voltage vector waveform produce methods.

4.Dead compensate function, realize low frequency and large output torque control.

5. Automatic slip compensates.

6. At most 7 steps speed control and 8 steps acceleration control can be realized.

7. 6 programmable output control terminals.

8. Internal PID function, realize high performance closed loop control (with optional PG card,closed loop control with encode  ).

9. PID regulates DC braking.

10. Speed pursues starting and restarts after momentary power loss.

11. Forced communicated function, support standard RS485 and CanBus, supply remote keyboard control function.

12. Humanization display menu with liquid crystal display, and LED display 3 state parameters simultaneity.

13. Special converse module (IGBT) temperature control function, adjustable fan control, timely reduce motor noise and temperature.

14. High-efficient faults inquiry and record function conveniently obviate the fault.

15. Special converse module (IGBT) temperature control function, adjustable fan control, timely reduce motor noise and temperature.

16. Unique design, make frequency converter least pollution to the power.

17. Outstanding behave 3-phase AC synchronous motor of permanent magnetism control.

18.  Ambient temperature: -10~40 degree C
19) Altitude: 0~1000 m, 1000~4000 m with derating 
20) 30 kinds of protection function 
21) User can plug in option card to achieve specialized inverter for different application 
22) Avoid high temperature and moisture and avoid being wetted due to raining, with the humidity below 90%RH (not dewing).
