auto voltage adjustment Multi-paraemeter monitoring AC Variable Speed Drives

motor variable speed ac drive
V/F & sensorless vector control type,
auto voltage adjustment
perfect saving energy project

ED3100 series variable speed ac drive

1.Advanced vector control algorithm,can realize the decoupling control of motors, and reach SVC current vector control mode and V/F control mode
2.150% low frequency moment output,1:100 speed control range, control accuracy of the non PG vector control speed can reach to 0.1%
3.Frequency inverters between 0.75kw~18.5kw with built-in brake unit,if fast-action braking is needed,can connect brake resistance directly; 160kw and up with direct current(DC) reactor ,which can increase the power factor of the output side, increase efficiency and stability of the AC Driver, eliminate the influence of higher harmonics produced at the input side toward the frequency inverter,decrease the interference to periphery
4.Built-in auto-compensation torque function,built-in PID regulator and built-in RS485 communication interface, provide full support to MODBUS communication protocol
5.Restart function of torque tracking ,realize smooth and non-impact start of the revolving motor
6.Multi-paraemeter monitoring and adjustment online
7.Connected with various ancillary equipment, such as PLC,IPC and meters
by various input and output ports and control modes
8.LED,LCD operation panel optional for convenience and efficiency
9.Supply pulse input and output to achieve digital closed loop control method
10.With automatic energy saving feature, at which the current is lower than V/F at the same
frequency; the voltage automatic adjustment to keep the output voltage constant when the
power voltage changeatmosphere
11.Complete independent air flue design increase vigilance against dust
12.All boards processed by conformal coating13. Perfect function of protection

Be optional during both starting and stopping, the operating frequency: 020Hz,operating voltage level: 020%,operating time: settable within 020s


Jogging frequency range: 0.1Hz50.00Hz,jogging acceleration and deceleration time: 0.13600s.

Built-in PID

It is convenient for forming closed loop control system, applicable for course control like pressure and flow, etc.

Multi-speed operating

Realize multi-speed running by built-in PLC or control terminal.

Weaving wobble frequency

Can get wobble frequency of adjustable central frequency

Auto voltage adjustment

When main voltage changes, the output voltage may be kept constant by adjusting PWM output (AVR function).

Auto energy-saving running

According to load condition, V/F curve can be optimized automatically to get the aim of energy-saving running.

Auto current limiting

Limit in-service current automatically, so as to avoid tripping for fault caused by frequent over current.
