WEM CHV 100 SERIES AC DRIVES







Product Description:

WEM CHV 100 SERIES AC DRIVES

3 phase 220V/230V±15% 1.5kW~45kW
3 phase 380V/415V/440V/460V/480V/525±15% 1.5kW~2MW
3 phase 660V/690V±15% 11kW~2.8MW


◆ Control Mode
Sensorless vector control (SVC), Vector control with PG (VC), V/F control.
◆ Dual-CPU control platform:16bit DSP is responsible for current vector arithmetic while 32 bit ARM is in charge of control function
◆ Static and rotation motor parameters autotune, ensure excellent vector control
◆ Achieve high accuracy close-loop speed control and torque control
◆External LCD panel can monitor three parameters at the same time.Chinese/English selectable. Parameter copy function make several drives commisioning more convenient.
◆ Overload Capacity: 60s with 150% of rated current, 10s with 180% of rated current.
◆ Starting Torque: 150% of rated torque at 0.5Hz (SVC);
180% of rated torque at 0Hz(VC).
◆ Speed Adjusting Range: 1:100 (SVC); 1:1000 (VC)
◆ Speed Accuracy: ± 0.5% of maximum speed (SVC); ± 0.02% of maximum speed (VC)
◆ Carrier Frequency: 1.0kHz~16.0kHz.
◆ Frequency reference source: keypad, analog input, HDI, serial communication, multi-step speed, simple PLC and PID. The combination of multi- modes and the switch between different modes can be realized.
◆ Torque Control Function: Provide multiple torque setting source.
◆ PID Control Function
◆ Simple PLC or Multi-steps Speed Control: 16 steps speed can be set.
◆ Traverse Control Function
◆ Length and Time Control
◆Offer RS485 communication which support standard modbus RTU and ASCII protocol
◆Built in DC reactor above 18.5kW to,improve power factor and efficiency
◆Built-in braking unit.
◆ Non-Stop Function while instantaneous power failure
◆Speed Trace Function: Smoothly start the running motor.
◆ QUICK/JOG Function: User defined shortcut key can be realized.
◆ Automatic Voltage Regulation (AVR): Automatically keep the output voltage stable when input voltage fluctuating
◆ Up to 29 fault protections:
Protect from over current, over voltage, under voltage, over temperature, phase failure, over load etc.
Typical applications:
Elevator, Crane,Textile,Paper,Iron & Steel, Printing Industries
