1SK3000 Series Sensorless VectorControl InverterOperation Manual2 Thank you very much for your buying SK3000 series sensorless vector control inverter. Before use, please read this manual thoroughly to ensure proper usage. Keep this manual at an easily accessible place so that can refer anytime as necessary. Safety PrecautionsPlease read this operation manual carefully before installation, operation, maintenance or inspectionIn this manual, the safety precautions were sorted to “WARNING” or “CAUTION”.WARNINGIndicates a potentially dangerous situation which, if can notavoid will result in death or serious injury. CAUTIONIndicates a potentially dangerous situation which, if can notavoid will cause minor or moderate injury and damage the device. ThisSymbol is also used for warning any un-safety operation.In some cases, even the contents of “CAUTION” still can cause serious accident. Please follow these important precautions in any situation NOTE indicate the necessary operation to ensure the device run properly.Warning Marks are placed on the front cover of the inverter.Please follow these indications when using the inverter.3TABLE OF CONTENTSINTRODUCTION.31.1 Technology Features .31.2 Description of Name Plate .41.3 Selection Guide .41.4 External Dimension.51.5 Braking resistor/unit selection.82.

Programmable Open Collector Output:Provide 1 output terminal (open collector output or high-speed pulse output) Relay Output: Provide 1 output terminal.Analog Output: Provide 1 analog output terminal, whose output scope can be 0/420 mA or 010 V, as chosen. Main Control FunctionControl Mode: Sensorless Vector Control (SVC), V/F Control. Overload Capacity:60s with 150% of rated current, 10s with 180% of rated current. Starting Torque: 150% of rated torque at 0.5Hz (SVC). Speed Adjusting Range: 1:100 (SVC)Speed Accuracy: 0.5% of maximum speed (SVC) Carrier Frequency: 0.5kHz 15.0kHz.Reference Frequency Source: keypad, analog input, serial communication, multi-step speed, PID and so on. The combination of multi- modes and switching between different modes can be realized.Torque Control Function: Provide multiple torque setting source. PID Control FunctionMulti-Step Speed Control Function: 8 steps speed can be set. Traverse Control Function3None-Stop when instantaneous power off.Speed trace Function: Start the running motor smoothly. QUICK/JOG Key: User defined shortcut key can be realized.Automatic Voltage Regulation (AVR) Function:Automatically keep the output voltage stable when input voltage fluctuating.
