The speed of the cam indexer determines the automation system, the efficiency in actual production, how to achieve the control of the indexer?
We know that the cam indexer itself has no driving function. Only under the driving of the motor can it realize its unique turning function. Therefore, the control of the indexer speed is realized as the speed of the driving motor of the indexer. Take effective control. The sensing device in the automation system completes the information transmission of the indexer and the control system, and the motor speed is fast and slow, and the frequency converter speed control method is commonly used.
Using the speed control mode of the frequency converter is to change the running frequency of the motor through the frequency converter, thereby changing the speed of the motor. The frequency of the motor inverter can be set freely, and the different output frequencies make the motor have different speeds. This method of using the frequency converter to change the power frequency for speed regulation has a large speed regulation range, good stability and smoothness, and hard mechanical characteristics. The use of the indexer is considered in terms of cost and practicality, and most of the motors are used. Ordinary gear reduction motors, using inverters are the most ideal tools in terms of cost, design simplicity, and operational efficiency.
The speed and frequency of the motor used by the cam indexer are proportional. At the same time, the inverter of the indexer motor also has the function of energy saving and protection of the motor. The inverter does not increase the speed, but the torque. This is also a correct statement. Therefore, when adjusting the inverter, try to ensure that the motor is within the rated power range. If the unilateral increase in speed is not inferior to the inverter energy saving. The characteristics increase the burden on the motor and increase the wear and aging heat, so it is not recommended. In an automation system using a indexer drive, the speed of the motor is generally set to a constant value. In special cases, the inverter of the motor is adjusted, and the whole body is moved. After all, the indexer is in the indexer system. One of the main components, its speed changes, will affect every station
