The AEG-VF31 series frequency converter is a high-performance open-loop vector type frequency converter designed specifically to drive low-voltage three-phase asynchronous motors, thereby enabling customers to achieve energy-saving and process improvement goals. The power range is from 1.5kW to 630kW, covering almost the entire power usage range of low-voltage three-phase asynchronous motors. Powerful software features and comprehensive protection and alarm settings make your speed control system simpler

Features
Frequency upper and lower limit operation: The upper and lower limit values of the frequency command can be set separately without adding peripheral devices to limit the motor speed.
Carrier frequency: PWM modulation method, adjustable from 1.0 to 16kHz.
Built in simple PLC: can automatically control the operation of the system according to the pre arranged running time, direction, and frequency.
Automatic torque boost and automatic slip compensation function: compensates for the insufficient output torque when the frequency decreases.
Torque limiting function: When there is a sudden load change, the high-precision torque limiting function under vector control is used to limit the output torque and protect the machinery.
Maintain frequency command operation: temporarily maintain the rise/fall of frequency during acceleration or deceleration.
Energy saving control: Always provide the motor with the voltage that maximizes its efficiency based on the load and speed.
Automatic Voltage Regulation (AVR): It can automatically maintain a constant output voltage when the grid voltage changes.
Jogging function: Jogging function is invalid during operation; During the jog process, the running function is invalid.
Frequency jump control: prevents mechanical system vibration, automatically avoids resonance points during constant speed operation, and is also suitable for dead zone control.
Over torque detection: If the torque generated by the motor exceeds the over torque detection value, the contact will "close".
Swing frequency function: Especially suitable for industries such as textiles and chemical fibers, as well as occasions that require lateral movement and winding functions.
Fixed length function: Given length control function.
Timing control: It can achieve timing control of the frequency converter without the need for peripheral devices.
PID control: Integrated PID regulator with preset PID setpoint and Auto/Man. mode
Sleep wake-up function: automatically starts or enters a sleep stop state according to the set value.
The working voltage range is wide, and the load capacity is ensured through voltage reduction modulation technology at low voltages. To meet strict industrial standards for power grid surges (induced lightning strikes), power grid noise, and electrostatic anti-interference.
The entire series of machines adopts an independent air duct design, making it easy to cope with harsh industrial environments.
