E2000 series AC drives(0.2-220KW)
Application:
E2000 series of AC drives is our newest product of sensorless vector control type. The system function is enriched and advanced vector control core is adopted. With the high utilization rate of voltage, the high power factor, the fast dynamic response, high precision, and low noise. E2000 series can meet wide-ranging application.
Characteristic:
● Auto torque promotion and auto slip compensation realizes larger output torque at low frequency.
● User-defined curve, V/F curve can be adjusted.
● Lower-noise, carrier-wave frequency can be adjusted from 2KHZ to 10KHZ.
● Control protection is immediate and reliable, which improves system stability.
● Built-in filter is optional
● Compatible with NPN and PNP types.
● Advanced vector control technology realizes more precise control and more excellent performance.
● Torque is elevated automatically, starting torque reaches 150% at 0.5Hz, and torque control precision reach ±5%.
● Output frequency is 0.50-650Hz. The highest resolution is 0.01Hz.
Main function:
● Built-in braking unit.
● Built-in EMI filter.
● Kinds of load type: beeline type, square type, under-defined V/F curve type and auto torque compensation type.
● Jogging speed control, multistage speed-control, external analog signal speed control and PC/PLC speed control.
● Standard RS485 communication interface, PC/PLC control by MODBUS communication and several inverters can be operated at the same time.
● Frequency source includes given digit, given analog voltage and given MODBUS, etc.
● Frequency source includes given digit, given analog voltage and given MODBUS, etc.
● With double-polarity NPN and PNP type.
● 6 digital input terminals, each of which can be used as user-defined function terminals. 2 analog input terminals, one of which can be used to input voltage (0~5v, 0~10v) and the other can be used to input current (0~20 mA, 4~20 mA).
● 1 digital output terminal, 1 multifunction relay output terminal and 2 analog output terminals. One of analog terminal can be used to output voltage (0~5v, 0~10v) or current (0~20mA) and the other can be used to output current ((0~20 mA or 4~20 mA).
● With the twinkling display of preset frequency, running frequency can be easily set before running.
● Current stalling adjusting.
● Built-in DC braking.
