AS850 series servo drive for permanent magnet synchronous motor (PMSM), is KEWO own developed hydraulic electric servo drive system for injection molding machine energy saving. It has following advantage, high energy saving, high power factor, quick response and high accuracy control, etc. AS850Z has powerful overload capability even under low speed, 180% rated torque for 30s under 0 speed is possible to ensure good pressure keeping ability.
Output frequency range: 0 to 400Hz.
Input voltage: 3 phase 380V±15%, 2.2kw to 75kw
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.
