380V 415V 440V Frequency Converter 55KW 3 Phase VFD For AC Motor
Description of frequency converter
As the third generation of flux linkage vector torque control motors, ST310 series is powered by
DSP dual-core professional control motor chip, providing the international leading V/F control
algorithm, and realizing the high-precision flux linkage vector torque control. This device has a
variable-frequency control mode and is widely used in the control of high-speed precision, fast
torque response, and high-performance low-frequency applications. By integrating torque, speed,
and position control, high-performance customer applications can be met.
Software design of VFD
1. In the control mode, we are working on a closed-loop vector control and a V/F vector control
including open loop vector control.
2. The maximum frequency of the control is 3000Hz
3. In order to avoid the impact of hardware protection components, wave-by-wave current limiting is
the first line of defense whenever the system is loaded with current.
4. Capacity of conventional overload: 130%, 150% 60S, 180% 10S, 200% 10.5S.
5. The tracking speed has a startup mode, small current and voltage impact, and accurate tracking speed
with an accurate tracking speed
6. A four-time fault record records the current, voltage, and temperature as part of the fault process of the
frequency converter, making fault analysis easier
7. The panel stores a group of parameters for convenient debugging.
8. Carrier frequency: 0.7KW x 16KW. The carrier frequency can be adjusted automatically based on frequency
conversion temperature and operating frequency in order to ensure reliable operation, even when the frequency
conversion temperature rises low to ensure reliable operation.
9. In addition to temperature detection module, the frequency converter overheat alarm can be set at a specific
temperature, and the default fan starting at the temperature is flexible, therefore improving unit life.
10. It supports up to 16 speeds at a time.
