COG LCD for Portable Device

Part Name: CDP312R device part

Machine No.: ACS800

This product is a portable frequency converter device sold by AB*. Its display module is made of a COG LCD and a light-guide plate. COG LCD support 14 languages and its display module is 4*20. Its backlight is one-piece light-guide plate, which is of very good quality, stable function and long use life.

This machine model #ACS800 is mainly used to is to reduce the impact load caused by the motor at start-up, to control the speed of the motor, to lengthen the start-up time, to smooth the current, and to achieve the purpose of soft start, while also improving the efficiency of the power grid and the motor. Inverter is mainly used for energy saving. Through adjustment, the output voltage, current and frequency can be changed. General speed-regulated motors use inverters to protect the motor in the following areas: over-voltage protection, under-voltage protection, over-current protection, phase loss protection, reverse phase protection, overload protection, grounding protection, short circuit protection, Overclocking protection and stall protection.

Cons:

1. High cost: its price is much more expensive than the soft protection of the computer.

2.Because of the current inverter pulse modulation form, when the inverter is running, high harmonic current is generated on the power supply side, and the voltage waveform is distorted. After the power system is polluted by harmonics, it will affect the operating efficiency of the system in a small way and damage the equipment in a serious way.

As a result, the safe operation of the power system is endangered.

3.Overload causes the inverter to jump more frequently. When an overload phenomenon usually occurs, the motor has a strong overload capacity.

The motor parameters in the parameter table are set properly, and generally the motor overload will not occur. Poor overload alarms easily occur.
