CMC-HX Induction Motor Controller – Electronic Soft Start Technology for AC380V Systems

Description

Features

● SCR triggering close-loop control algorithm

The SCR close-loop control is specially designed for standard load and heavy load. User can choose current-limit start or voltage ramp start according to load conditions so as to realize absolutely smooth start without torque oscillation.

● Unique load application parameters

It is built-in 10 kinds of load types for users to choose. It provides a unique start control curve for each type of load to make soft start match the load, so as to achieve the best start and stop.

● Multiple start and stop modes

Voltage exponential curve start, voltage linear curve start, current exponential curve start, and current linear curve start. Programmable kick start torque and start current limit can be applied in each mode. According to the different loads, you can choose the corresponding start curve to achieve the appropriate starting effect. The device is provided with a variety of stop modes including programmable soft stop, free stop, braking, and pump stop. Unique basic algorithm makes the motor start and stop accurately and smoothly.

● Advanced communication function

Standard Modbus RTU communication. Optional Ethernet/GPRS communication module makes user’s network connection control easier and improves the system’s automation level and reliability.

● Analog signal control

Users can input 4-20mA or 0-20mA standard signal, and conduct upper and lower limit setting of analog to achieve the start and stop control of motor and alarm. The data (pressure, temperature, flow, etc.) can also be transmitted via a soft starter.

4-20mA or 0-20mA standard analog signal output function.

● Fireproof material

The product of below 90KW is in plastic structure made with inflaming retarding ABS material; for the product of 90KW and above, the upper cover is in plastic structure and main frame is made of aluminium-zinc plate with features of heatproof and corrosion resistance.

● Movable panel

The panel can be moved to equipment operating surface through machine interface for remote control.

● Powerful anti-interference property

All external control signals are subject to optoelectronic isolation, and different anti-noise levels are set to adapt to the application in special industrial environments.

● Dual parameter function

With two sets of basic parameters, it can control two motors with different power respectively.

● Self-adaption of power frequency

Self-adaption of power frequency 50/60 makes user easy to use.

● Dynamic fault memory

Up to 10 failures can be recorded, making it easy to find the cause of the malfunction.

● Perfect protective function

It detects current and load parameters, having overcurrent, overload, underload, overheating, phase failure, short circuit, three-phase current imbalance, phase sequence detection, frequency error and other functions.

● HMI

LCD liquid crystal display panel; support English display.
