ES500A High Performance VFD
ES500A is a versatile high-performance VFD of Epsivo with optimized vector variable-frequency technology. With its high-performance current vector technology, it can easily drive a wide range of asynchronous and permanent magnet synchronous motors. The technical and performance problems encountered in applications such as cable, machine tool, metal product, petrochemical, natural gas, lifting equipment, papermaking, textiles, printing and dyeing, and ceramics can be easily solved.
AC 3PH 220V~240V 0.75~200kW
AC 3PH 380V~415V 0.75~710kW
Application:
Papermaking, lifting machinery, elevators, CNC machine tool, precision injection molding, metallurgy, mining, electric power, petroleum and chemical industry, which highly require speed control for synchronous motor driving or asynchronous motor driving.
1. Driving various motors
It supports vector control of AC asynchronous motors and synchronous motors, and supports vector control of permanent magnet synchronous motors without position feedback.
2. Excellent permanent magnet synchronous motor control performance
It drives permanent magnet synchronous motors smoothly and efficiently (including the PMSM without speed or rotor position sensors) to achieve higher energy efficiency;
Direct drive is possible on low-speed control industrial equipment, achieving higher energy efficiency and better control performance.
3. Optimized vector control technology, bringing breakthrough in motor control performance
SVC speed control ratio is increased to 1:1000; SVC replaces FVC when the output torque is greater than 10%; SVC winding and unwinding torque accuracy is ≤ 5%.
4. High-performance vector control, improving equipment accuracy
The maximum output frequency of 500Hz achieved with vector control enables high-precision speed output within 10 times the weak magnetic speed regulation range.
5. Large torque at low speeds, improving the low-speed control performance
In the closed-loop vector mode, the linearity deviation of the torque line is within 3%; the torque output is stable, the low-frequency torque is large, and stable loaded operation at ultra-low speed and 0.01Hz can be achieved. The torque mode and speed mode can be easily switched.
6. Instantaneous power loss without shutdown
In the event of a momentary power failure or sudden voltage drop, the VFD reduces the output speed and compensates for the voltage drop by feeding energy back through the load, so as to maintain the drive in operation for a short period of time.
7. Built-in adaptive PID function module
Two built-in PID parameter groups can be automatically switched according to deviations, DI terminals and frequency conditions. The given and feedback sources are various and practical. The PID feedback loss detection function facilitates user to perform fault diagnosis.
8. Extensive expansion function cards
With modular design concept, ES500A has superb expansion functions. Users are free to select different communication cards, PG cards and other expansion cards according to their needs, for example, ModBUS / CANopen / EtherCAT communication card, differential / rotary / open collector PG card.
9. Industry application macro function
Designed for the special requirements for performance functions in industry applications, such as winding machines, winches, cranes, extruders and presses, the industry application macro function realizes the one-key initialization function, reducing the workload and technical requirements of the front-line debugging personnel.
10. Powerful upper computer monitoring software
Extensive background monitoring functions which facilitate on-site data collection and debugging; online oscilloscope function; batch uploading and downloading parameters; displaying Group U0 parameters in real time; and monitoring and diagnosis functions.
Good features based on our professional production.
