Product Description

Product Description

Core Product Positioning
 
The ES580P is a Made-in-China frequency inverter dedicated to pump applications by Cumark. Focused on fluid transfer needs such as constant pressure water supply, industrial circulating water, and municipal secondary pressure boosting, it features "precision master-slave coordinated control + efficient multi-pump linkage" as its core. Compatible with both single-pump independent operation and multi-pump parallel expansion, it covers a power range of 0.75kW-560kW, balancing energy efficiency, redundancy reliability, and scenario flexibility.

Core Functions: Master-Slave Mode & Multi-Pump Control
 Master-Slave Coordination Logic: Supports "1 master + N slaves" (up to 8 pumps). The master drive synchronizes commands via CAN bus/DI hard wire, handles PID constant pressure/flow calculations, while slave drives execute speed commands from the master. It supports dual backup of communication and terminals, enabling emergency switching when communication fails in industrial scenarios.

Mode Classification:Multi-Pump Confluence: The master drive provides unified control, and slave drives have no independent commands. Suitable for constant pressure water supply and injection molding machine oil pump confluence; slave pumps automatically enter sleep mode for energy saving under low load.

Multi-Master Coordination: Multiple masters coexist and can switch between confluence and shunt modes; slave drives support independent PID control. Suitable for zoned water supply and complex hydraulic systems.

Fault Redundancy Switching: When the master drive fails, the slave drive automatically takes over within 0.5 seconds via DI signal to avoid water supply interruption. Ideal for 24/7 continuous operation scenarios (e.g., chemical circulating water).

 Features of Multi-Pump Control
 
Intelligent Switching & Load Balancing: Automatically adds/removes pumps based on pressure/flow thresholds (e.g., 0.8MPa for pump addition, 0.6MPa for pump reduction). Supports two sequences: "Priority to pumps with the least running time" and "Priority to efficiency grade," balancing pump group wear and extending overall service life.

Precision Regulation Capability: PID pressure fluctuation < ±0.02MPa, speed synchronization accuracy < 2%, meeting the requirements of stable water pressure for high-rise buildings and precise flow for industrial processes.

Full-Scenario Protection: Built-in dry pump protection (52.09-52.13, judged by torque), water leakage detection (53.04-53.09, two detection methods triggering alarms/faults), overpressure, overcurrent, and overheating protection. Compatible with different media such as clean water and chemical liquids.

Energy-Saving Design: Slave pumps enter sleep mode under low load, with only the master drive maintaining pressure at a low frequency. Saves 30%-55% more energy than power frequency operation, suitable for scenarios like low water consumption at night in residential areas and pressure holding of injection molding machines.

Typical Application Scenarios
 Municipal/Civil Constant Pressure Water Supply: Suitable for high-rise residential buildings (32+ floors) and commercial complexes. Adopts 1-master-3-slave architecture; automatically adds pumps to maintain pressure during peak hours and puts slave pumps to sleep at night, saving up to 180,000 kWh of electricity annually.

Industrial Circulating Water/Process Water Supply: For chemical workshops and steel mill cooling systems. Uses dual communication + terminal links for 24/7 continuous operation; soft start/stop prevents pipe water hammer, reducing maintenance costs by 70%.

Injection Molding Machine Hydraulic Oil Pumps: For injection molding machines of 380 tons and above. 1-master-2-slave confluence; multi-pumps output large flow at the same speed during injection, and slave pumps sleep during pressure holding. Product qualification rate increases from 96% to 99.5%.

PV-Complementary Water Supply: Compatible with ES580-PV model, supporting dual input of solar energy and municipal power. Uses solar energy to drive multi-pumps during the day and switches to municipal power at night. Suitable for rural centralized water supply and irrigation in remote areas.
