EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual Preface Thank you for purchasing EM630/TC6A series inverter. Document No.: 31010030 Issue Date: 2014-04 Version: 103 EM630/TC6A, a high-performance inverter series specially developed for hoisting, is widely used for tower crane hoisting, trolley hoisting, slewing and travel closed-loop. Default parameter settings are adjustable according to applications of F20.00 selection in the hoisting industry . Main Features: Closed-loop vector control and steady performance at high torque and low frequency: smooth output of rated torque 0 Hz/150%, so that a hoist performs stably during start-up, hoisting and decline. Zero servo function:
offers the second type safety protection to hoist under the condition that an encoder is connected by driving motor to hold full load in the air or let it go down slowly even when the braker does not work. Overspeed protection: When an encoder is connected, overspeed stop protection and overspeed operation protection are provided to timely discover abnormalities of speed and braking force during hoisting to prevent slip accident. Braker control logic: Braker control logic controls hoist to open or close at reasonable sequence, which maintains the operation safety and extends the service life of braking system. Wide voltage input range and automatic voltage stabilization:
These functions meet torque output requirements of hoist even when voltage of power grid drops. Wide speed regulation range: This meets the requirements for light load at high speed and heavy load at low speed, thereby improving operating efficiency of hoist. Please read this manual carefully before using EM630/TC6A and keep it properly. Before connecting EM630/TC6A and a motor for the first time, please configure the motor nameplate parameters including rated frequency, rated power, rated voltage, rated current, rated rotation speed, rated power factor, and motor connection.
