LCGK LC410 3-Phase Vector Control VFD, 1.5–500 kW | RFQ Sourcing Details

Product overview The LCGK LC410 is a general-purpose, voltage-source AC-DC-AC variable-frequency drive for industrial motor control. Listed power options span 1.5–500 kW. The drive accepts 3-phase 380–460 V input with a stated ±15% tolerance and provides an output adjustable from 0 V to the rated input voltage.

Available control methods include V/F, sensorless vector control (SVC), and flux vector control (FVC). Control and integration A standard RS-485 interface supports the Modbus-RTU protocol for connection to compatible control systems.

Built-in PID control is provided for closed-loop regulation of process variables such as pressure, temperature, and flow. The drive supports asynchronous motor control, expansion cards, and user-programmable PLC cards described as using programming methods compatible with the H1U PLC series.

The removable control panel has a dual-line display. Operating capabilities The listed output-frequency ceiling is 500 Hz. Overload ratings are stated as 150% for 60 seconds and 180% for 3 seconds in G mode, or 120% for 60 seconds and 150% for 3 seconds in P mode.

Listed functions include speed tracking, instant stop, and acceleration or deceleration as short as 0.1 second. The stated efficiency is 96%, and the enclosure rating is IP20. Braking and protection A braking unit is listed as standard and built in for 1.5–22 kW models.

For 30–37 kW models, a built-in braking unit is optional;configurations above 37 kW are listed for an external braking arrangement. Protection functions include overcurrent, overvoltage, undervoltage, overheating, phase loss, overload, and short-circuit protection.

The drive can record operating status associated with a fault and includes an automatic fault-reset function.

Potential applications The documented application scope includes industrial motors and pumps, CNC machine tools, forging machines, textile machinery, Roots blowers, lifting equipment, plastics machinery, petroleum equipment, and food machinery.

Suitability still depends on the selected LC410 rating, motor nameplate, load behavior, duty cycle, environmental conditions, and required control method.

Procurement questions to confirm Before ordering, the buyer should confirm the exact converter model against the motor's voltage, rated current, power, speed range, and overload demand.

Confirm whether G mode or P mode is appropriate, whether an internal or external braking unit and braking resistor are required, and which expansion or PLC card is included.

Also verify enclosure and cabinet requirements, cooling and derating conditions, EMC measures, fieldbus needs beyond Modbus-RTU, package type, documentation, commissioning support, and the warranty term for the quoted configuration.

Source information lists both 18 months and one year in different sections, so the applicable written warranty should be resolved in the purchase documents.
