Cumark ES580/ES580L Crane and Hoist Variable Freq | RFQ Sourcing Details

The Cumark ES580/ES580L is a variable frequency drive designed for AC motor control in cranes, hoists, elevators, lifting machines, and material-handling systems. It uses an AC-DC-AC architecture with PWM switching and supports sensorless vector control (SVC) and flux vector control (FVC).

A braking unit is included for lifting applications requiring controlled deceleration and quick stopping. Published electrical options include 220 V, 380 V, 500 V, and 690 V three-phase input classes with a stated ±15% voltage tolerance. The output-frequency range is 0–599 Hz.

Listed series power ranges are 0.75–75 kW for 220 V, 1.5–800 kW for 380 V, 18.5–1200 kW for 500 V, and 15–1400 kW for 690 V. Another source specification states a 0.4–710 kW range, so buyers should confirm the available range for the exact ES580 or ES580L configuration being quoted.

The drive is specified for 200% starting torque at 0.25 Hz in SVC mode and 200% at 0 Hz in FVC mode. Published overload ratings are 150% of rated current for 60 seconds in heavy-load operation and 120% for 60 seconds in general-load operation.

Available functions include speed-tracking restart after a momentary power interruption, switching among as many as four motor groups, torque limiting, stall control, IGBT temperature monitoring, and fan management.

Protection functions listed for the series include overvoltage, undervoltage, overcurrent, overload, phase-loss, short-circuit, and brake-chopper overload protection. Built-in Modbus communication is stated, with Profibus-DP, CANopen, Profinet, and EtherCAT support also listed.

Buyers should verify whether these additional protocols require optional hardware or a particular model configuration. The stated operating temperature is -10°C to 40°C, with automatic derating from 40°C to 55°C. Cooling is by forced air with an internal fan.

Published enclosure information lists IP20 open-type construction and IP40 fully enclosed versions for some small-to-medium power models. Procurement should be based on the exact motor and lifting duty rather than the series description alone.

Before ordering, confirm the complete model code, motor rated voltage and current, required control mode, braking resistor requirements, duty cycle, enclosure, communications interface, installation altitude, ambient conditions, and cabinet ventilation.

Buyers should also request model-specific wiring diagrams, parameter documentation, dimensional drawings, and applicable certification records. The listed warranty is 20 months, but its start date, coverage, exclusions, and service process should be confirmed in the purchase agreement.
