SPASI23 Robot spare parts

The main circuit is the power conversion part that provides voltage regulation and frequency modulation power supply for asynchronous motors. The main circuit of frequency converters can be generally divided into two types:

Voltage type is a frequency converter that converts the DC of the voltage source into AC, and the filtering of the DC circuit is a capacitor.

Current type is a frequency converter that converts the DC of the current source into AC, and its DC circuit filtering is inductance. It consists of three parts: a "rectifier" that converts power frequency power into DC power, a "smoothing circuit" that absorbs voltage fluctuations generated by converters and inverters, and an "inverter" that converts DC power into AC power.

And up to 200% overload capacity, providing strong environmental adaptability for frequency converters.

In terms of usage, its rotary shuttle design and clear menu format significantly simplify operation.

Product characteristics:

Three phase 380V 2.2KW, rated current 6.0A.

Support multiple control methods such as SVPWM, V/F control, vector control, etc.

Built in PID controller.

The frequency of the frequency converter cannot be adjusted up. If there is no hardware damage, it is usually caused by the maximum torque output of the frequency converter being less than the load lifting torque. To put it bluntly, the frequency converter has poor load carrying capacity.

. Acceleration time too short

In theory, the longer the acceleration time, the stronger the ability to improve with load. If the set acceleration time is too short, some frequency converters may display overcurrent or overload overheating alarms, but some may not display them, just stuck in a certain frequency range.

. V/F ratio too large

Some frequency converters, also known as torque boost, can sometimes fail to start normally if this parameter is set too high. Reducing it appropriately can solve the problem

. Vector control parameter mismatch

In vector control mode, the internal resistance, inductance, and other parameters of the motor need to be accurately measured and coordinated with the vector parameters of the frequency converter. After running for a period of time, the motor parameters overheat and cause deviation, which can cause excessive current and prevent the motor from starting normally. The frequency may also get stuck at a certain point, and re optimizing the parameters can solve the problem.
