EN630 Mini Flux Vector Variable Frequency Drive
Description
EN630 mini flux vector variable frequency drive uses the 32-bit DSP hardware platform, has a built-in PG card, and can achieve PG close-loop vector control through directing encoder to terminals. The VFD adopts advanced algorithm to support both velocity vector control and torque vector control, and consequently achieves high control precision, rapid response, excellent low-frequency characteristics and complete intelligent fault detection and protection functionality. The keypad of the variable frequency drive supports DCP speed controlling and copying functionality.
Power range
220V single phase: 0.4KW-1.5KW
380V three-phase: 0.75KW-1.5KW
Application
EN630 mini flux vector variable frequency drive can be widely used in food processing, machinery manufacturing, wire drawing machinery, printing machinery, textile industry machinery, cement processing, ceramics; it can also be applied as mini-watt drives in industrial controlling, such as in medical devices and metal tooling.
