Support

IVC2 only supports 2 channels of 100kHz high speed pulse input, and 3 channels of 100kHz high speed pulse output; IVC3 supports 8 channels of 200kHz for both high speed pulse input and output;

The most economic series of our PLC is IVC1S series, and its main features are:

1, it supports 6 channels of 10kHz high speed pulse input, and 2 channels of 100kHz high speed pulse output;

2, it supports 1 channel of RS485 and 1 channel of RS232;

3, it doesn't support extension module and can support maximum 60 IO;

4, it doesn't support real-time clock function.

The programming software is Auto Station, and it can support IL, Ladder and SFC 3 programming language; It doesn't support off line simulation function.

It is mainly used to prevent silk folding. When the winding diameter is at a specific value, the trajectory of the first repeated action will achieve the effect of coincidence. Too many yarns overlap to form silk folding, which brings hidden dangers to the unwinding of the next process. Therefore, it is necessary to add swing frequency, which is equivalent to adding appropriate disturbance in the regular operation process.

Tension has a great impact on spinning forming, and different sizes of spindles have different requirements for tension. Therefore, different speeds should be set according to different processes and spinning stages to accurately meet the needs of tension.

Pay attention to the anti reversal at the moment of starting the permanent magnet synchronous motor, and pay attention to the demagnetization of the synchronous motor caused by high ambient temperature.

The high temperature and humidity at the textile site have blocked the cooling air duct of the VFD and damaged the fan. The oil stain and corrosivity at the chemical fiber textile site are easy to produce friction static electricity at the chemical fiber textile site. Pay attention to moisture and corrosion prevention at the printing and dyeing site.

Fiirst, please check the closed-loop setting parameters are ok, according to the guide of operation manual. Then do below steps:

1. Please check P20.05=0x33 or not;
2. P20.11, do auto-tuning;
3. Check that the connection between encoder and motor is normal or fixed;
4. Try to fix the motor to test, and observe the output current;
5. Please set the speed to 30 or 40Hz to see the performance.

Sto fault is an adjustment fault. First, check whether the motor is blocked. Another big reason is that the motor parameters of the P02 synchronous motor are inaccurate. The parameters can be reset. Set the motor parameters according to the motor nameplate. Set P00.03, P00.04 and proceed. Spin self-learning. Extend P13.11 detection time. In addition, set SVC1 P00.00=1 is a better way.
