PLC is the abbreviation of programmable logic manipulator, which is a digital operation manipulator with a microprocessor for automatic control, which can load control instructions into memory at any time for storage and fulfillment.
PAC is an abbreviation for Programmable Automation Manipulator. The concept of PAC in industrial control is that the concentration of the control engine covers the various needs of PLC users and the information needs of manufacturing manufacturers.
The difference between PLC and PAC
1. The programming interfaces of the two are different, so they have different functions.
PACs are typically programmed in C or C++, resulting in an open architecture and modular design; PLC programs, on the other hand, are simple and capable of running programs with limited memory and discrete inputs and outputs.
2. PLCs excel in small-scale automation tasks, such as stand-alone operation (using triggers to turn on and off) or small-scale building automation (lighting, temperature control, etc.).
PAC prefers a messy and large-scale automation architecture, which is particularly suitable for multi-domain supervision and manipulation. Such as advanced and intelligent process control, motion control, drive control, vision applications and HMI.
3. Because the PAC's modules provide easy programmability, it is easy to load and unload components from the PAC. At the same time, simplified programming enables the supervision and manipulation of thousands of inputs/outputs (I/O).
The PLC is a cable-dependent control system, and the addition of equipment will increase the rated wiring. Routing in compact terminals is difficult with traditional methods, so manufacturers are now using prefabricated cable assemblies instead of discrete point-to-point wiring.

The inverter controls the leakage of the motor
Because the current at the input and output ends of the inverter contains high-frequency components, the leakage current formed by the high-frequency components when the inverter is driven is greater than that when the grid power supply is supplied. Because there are many varieties of circuit breakers, in some cases, even the inverter wires and motors ...
