ALPHA6810S Energy Saver works intelligently in the injection cycles. The motor speed is controlled synchronously with the tracking of pressure and flow, which is equivalent to using a variable pump instead of the actual fixed-displacement pump. And the original hydraulic system works adaptively to the machine running power, eliminating the energy loss caused by high-pressure overflow in previous system. Furthermore, the AC Drive makes the motor stop running under non-action state (Mainly the cooling state) thus enlarges the energy saving space and reduces the running noise as well as machine wear and temperature-rise. This series of inverter perfectly combines the injection machine and the asynchronous servo controller’s advantages of rapid dynamic response and strong instantaneous over-current ability. Because of this, the energy saving of oil pump is 25%~70%, and hydraulic oil extends its lifetime to 3 years.
Strong over-load capacity; protection to 250% instantaneous over-current
Three analog inputs (0~1A, 0~10V); multiple selection modes
Rapid dynamic response ensures the production efficiency.
Built-in switching of bypass (Cabinet integration); more reliable running
Bypass switching control mode doesn’t need the modification of injection related parameters after switching.
Soft start and tracking running reduce machine wear and extend lifetime of injection machine.
Pass EMC testing; no interference to original injection control system
Easy installation and debugging, free of alternation to original oil pump circuit
Retain the original injection control mode and its oil circuit
Optimal curve runs adaptively to the properties of injection oil circuit
Keep original injection techniques and its work efficiency
Runs synchronously with injection machine to extend machine lifetime without adjustment
User-defined control curves satisfy all kinds of injection techniques.
Direct proportional valve signal input; no transfer process
Energy saving rate varies among 20%~70% in different injection techniques.
Magnificent reduced heating; stable oil temperature; save higher than 30% cooling water
Extend sealants lifetime; reduce stoppage for maintenance; save large amount of maintenance fee
The energy saver is used together with injection molding machines.
