LCGK LC410 Three-Phase Variable Frequency Drive, | RFQ Sourcing Details

The LCGK LC410 is a general-purpose variable frequency drive designed to control industrial motors and pumps. The documented range covers 1.5–500 kW, with 3AC 380–460 V ±15% input and output adjustable from 0 V to the rated input voltage.

Supported control methods are V/F, sensorless vector control (SVC), and flux vector control (FVC). The drive uses high-carrier-frequency PWM control and an AC-DC-AC voltage-source architecture. For automation integration, the LC410 includes an RS-485 interface supporting the Modbus-RTU protocol.

Built-in PID control can support closed-loop regulation of process variables such as pressure, temperature, and flow. The stated output-frequency capability is up to 500 Hz.

The product information also identifies speed tracking, instant-stop functionality, removable control panels, expansion-card options, asynchronous motor control, and support for user-programmable PLC control cards. Documented overload capacity is 150% for 60 seconds and 180% for 3 seconds in G mode.

In P mode, it is 120% for 60 seconds and 150% for 3 seconds. Braking-unit configuration varies by drive size: units from 1.5 to 22 kW have a standard built-in braking unit;30 to 37 kW units offer an optional built-in unit;larger ratings require confirmation of the external braking arrangement.

Listed protection functions include overcurrent, overvoltage, undervoltage, overheating, phase loss, overload, and short-circuit protection. Fault-status recording and automatic fault reset are also stated.

Potential equipment categories include CNC machine tools, forging equipment, textile machinery, Roots blowers, lifting equipment, plastics machinery, petroleum equipment, and food-processing machinery. These examples do not establish suitability for a particular machine or operating environment.

Before procurement, the buyer should confirm the exact LC410 model against the motor nameplate, including rated power, current, voltage, frequency, duty type, starting torque, and overload profile.

Also confirm enclosure requirements because the listed protection level is IP20, along with ambient conditions, cooling and cabinet arrangement, cable lengths, EMC or harmonic requirements, braking-resistor needs, fieldbus or expansion-card configuration, and any required safety functions.

Warranty information in the supplied product details is inconsistent, so the applicable warranty period and terms should be resolved in the purchase documentation.

Certification coverage, documentation language, accessories, dimensions, weight, and final lead time should likewise be confirmed for the selected power rating.
