Synmot AC 380V Servo Drive For PMSM Of Injection Molding Machine
ZK AS850 series Servo Drive for Permanent Magent Synchronous Motor (PMSM):
High Positioning Accuracy
AS850 series servo motors feature incremental encoders with 20-bit level resolution which can improve low speed stability, smooth motor operation and enhance the accuracy of positioning.
Absolute type encoder with 17-bit level resolution is supported.
High Responsiveness
Up to 1 kHz frequency response.
Settling time below 1 ms.
7 ms acceleration time for speeds from -3000 r/min to 3000 r/min with an empty load!
(Note: The test record is of a 400 W motor with 60 mm frame size).
Output frequency range: 0 to 400Hz.
Input voltage: 3 phase 380V±15%, 2.2kw to 90kw
Pressure signal reference: external analog 0-10V, 0-1A.
Protection function: Input phase missing, input under voltage, over voltage, over current, over load, over heat, external disturbing .
Cooling method: force cooling
Mount: Wall mount
Function features
Energy saving: up to 60% energy saving compare to traditional fixed pump system. 75% is possible be achieved according to difference injection condition.
Lower oil temperature: reduce 5-10 degrees
High repeated accuracy: To achieve high accuracy flow and pressure control
Long pressure holding time: It is favorable for big wall thickness.
Quick response: frequency response up to 50ms.

Advantage:
The injection molding machine power consume take up 75% of system total in traditional constant flow of IMM.
It need difference flow and pressure during difference working stage of IMM such as mold close, injection, pressure holding, molding open. When the required over the setting pressure and flow, the flow and pressure will be adjusted by relief valve or proportional valve. this process call high pressure throttling. Up to 40-75% energy wasting during this stage.
Application:
1. Injection molding machine
2. pressure die casting machine
3 . brick machine
4. shoes machinery
5. Pressing machine
6. Aluminum extrusion machine
7. Hydraulic, CNC punching machine
8. Civil engineering machine
9. Other hydraulic machinery
