Soft starter is a motor control device that integrates motor soft start, soft stop, light load energy saving and various protection functions. It not only realizes the smooth and shock-free starting of the motor during the entire starting process, but also adjusts the parameters during the starting process, such as current limit value, starting time, etc., according to the characteristics of the motor load. The main function of the soft starter is to realize the soft start and soft stop of the motor and the energy-saving operation and DC braking of the motor. In practical applications, the soft starter can not only be used for single motor control, but also can be used in conjunction with PLC to realize multiple Motor control, with good economy and practicability. At the same time, some programs in the practical application of soft starter.
How to control soft start with buttons
1. First understand the secondary control loop of soft start. Generally, soft start has bypass contactor output node.
2. Know the load start-up time again. The best time to cut the bypass contactor is after the start-up process is completed.
3. The main circuit of the bypass contactor should be connected in parallel with the soft starter.
4. String the output node of the bypass contactor into the control loop of the bypass contactor, preferably a self-locking loop. Among them, the external contactor is used for direct starting, which is in a parallel relationship and requires electrical interlocking.
How to measure the quality of soft starter
1. Visual observation. Through visual inspection, we can observe whether the soft starter has the following phenomena: The soft starter has strong damage, and the damage is usually caused by collision, fire, water, dust, load short circuit, etc. Treatment method: It can be sent back to the manufacturer for repair depending on the damage.
2. Smell. Whether the soft starter body has a burnt smell, the damage is usually caused by excessive current or excessive load. Treatment method: It can be sent back to the manufacturer for repair depending on the damage.
3. Listen. Check the soft starter for any abnormal noise, and stop immediately if there is any abnormal noise. Do not connect power factor compensation capacitors to the starter output.
