Overview
However, the impact of leakage impedance on Siemens power module 6ES7505-0KA00-0AB0 $r $n is not only related to frequency, but also to the magnitude of motor current, making accurate compensation difficult. In recent years, some self compensating frequency converters have been developed abroad, but they require a large amount of computation and complex hardware and software. Therefore, most frequency converters are manually set and compensated by users. How to set the acceleration and deceleration time? The frequency change rate of the frequency converter during the starting and braking process is set by the user.

If the motor's moment of inertia J changes and the motor load changes according to the pre-set frequency change rate, there may be insufficient acceleration torque, resulting in motor stall, that is, the motor speed is not coordinated with the output frequency of the frequency converter, causing overcurrent or overvoltage.

When setting, the corresponding curve can be selected based on the load torque characteristics, but there are exceptions. When debugging the frequency converter of a boiler induced draft fan, the author first selected a non-linear curve for the acceleration and deceleration curve, and when the frequency converter was operated together, it tripped. Adjusting and changing many parameters had no effect, and then changed it to an S-curve to restore normal operation. The reason for this is that the induced draft fan rotates on its own due to the flow of flue gas before starting, and reverses to become a negative load. Therefore, the S-curve is selected to slow down the frequency rise rate at the beginning of starting, thereby avoiding the occurrence of frequency converter tripping. Of course, this is a method used for frequency converters without starting direct flow braking function. Torque vector control is based on the theoretical belief that asynchronous motors and DC motors have the same torque generation mechanism.
In the manufacturing industry, there are a large number of open-loop sequential controls mainly based on switch values, which perform sequential actions according to logical conditions and sequence actions; In addition, there is control of chain protection actions based on logical relationships that are independent of sequence and timing; And a large number of state variables such as switch values, pulse values, timing, counters, and analog over limit alarms are mainly used for data acquisition and monitoring of discrete variables.
