The frequency converter has rich practical experience in the spinning frame industry. The company's R & D personnel develop a special inverter for the spinning frame by continuously understanding its process flow, and can control the multi-speed process curve of the inverter;
In the initial stage, the inverter runs at low speed. After the low speed running command is cancelled, the inverter runs the multi-speed process setting curve, and the inverter accelerates to multi-speed 1 operation. As the length of the first section increases, the frequency gradually increases. For the length of the first section, the inverter runs at multi-speed 2, and the process changes at a constant speed.
★Features
◇ Change shift control function, can record the output of each shift. Full yarn, pulse signal loss alarm function. Multi-speed process curve control, reset function. Independent meter reset function for intermediate checks. The meter function, power-down save function, resumes power supply and continues to run from the segment and output frequency before power-down.
★Special features of spinning frame
◇Based on high performance speed sensorless vector control technology platform;
Designed for the application requirements of spinning machines in textile machinery, convenient installation outside the cabinet;
◇ Suitable for dusty industrial sites, the radiator is easy to clean;
◇ Sweep alarm function: After the inverter temperature exceeds the set value, remind the user to clean the radiator and fan;
◇ Rich indication signals: full yarn indication, disconnection indication, power failure indication, operation/stop indication, etc.
◇Easy operation, single button to complete the stop, full yarn clear, yarn break length is cleared.
★ Practice certificate
The performance of the inverter on the spinning frame is better than that of the ordinary inverter.
