Main Control Function

◆Control 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 Function.

◆Multi-Step Speed Control Function: 8 steps speed can be set.

◆Traverse Control Function.

◆Non-Stop when power is instantaneously cut off.

◆Speed trace Function: Start the running motor smoothly.

 B503, B503D(IP20) Key: User defined shortcut key can be realized.

◆Automatic Voltage Regulation (AVR) Function: Automatically keep the output voltage stable when input voltage fluctuating.

◆Up to 25 fault protections: Protect from over current, over voltage, under voltage, over heat, phase failure, overload etc.
