Universal control module for gun AC servo driver

The invention belongs to the technical field of circuit design of AC servo drivers in gun servo systems, and particularly relates to a universal control module for a gun AC servo driver. According tofunctions to be realized by a circuit of the control module, a control circuit is divided into an interface module, an I/O isolation module, a power conversion module, a communication module, a position calculation module, an operation and control module, a logic control module and a signal conditioning module according to a universal and modular design method, wherein the communication module comprises a CAN communication module, an RS485 communication module and an RS232 communication module; the position calculation module comprises a rotary transformer position calculation module and a photoelectric encoder position calculation module, then circuit design is conducted on all functional modules of the control circuit, electronic components involved in the circuit are patch products which are small in size and reliable in function, and printed board layout and design are conducted according to a multilayer board design method for minimizing layout, so that a control module product with the size of 130mm*85mm is formed.
