1. Control the start, stop, speed and so on of the servo motor;
2. Carry out various maintenance on the motor (overload, short circuit, undervoltage, etc.)
3. React to external signals and control servo motors (position, speed, torque) through internal PID conditioning;
The controller is the part that controls the speed of the motor, and is also the center of the electric system of the electric vehicle, which has the functions of under-voltage, current limiting or over-current maintenance. The functional controller also has a variety of riding modes and a self-check function for the electrical parts of the whole vehicle. The controller is the central component of the energy management system and various signal processing of electric vehicles.
At present, the mainstream servo drives all use digital signal processors (DSPs) as the control center, which can complete the more complex control algorithms, complete the digitalization, networking and intelligence.
Power devices generally use the intelligent power block (IPM) as the center of the design of the drive circuit, IPM integrated drive circuit, at the same time has overvoltage, overcurrent, overheating, undervoltage and other fault detection and maintenance circuits, in the main circuit also participate in the soft start circuit, in order to reduce the impact of the start-up process on the driver.
1。 Hardware articulation. How can the drive connect with multiple sevos without disturbing each other. Then at this moment you need to have a switching device, if the current driver is connected to A sevo. So what kind of equipment do you choose to completely connect the cable to device B, including shielded cables, This is a big problem, and it is impossible to ensure the stability of the signal after switching, due to the direct hard-wire switching of the cable.
2. In terms of software, we can distinguish whether the current device A is device A or device B, and we can complete the immovable action by controlling the program, and the program can be completed.
Servo motor refers to the engine that controls the mechanical components in the servo system, and is a direct transmission device of the auxiliary motor.
The servo motor can make the control speed, position accuracy very accurate, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal, and can respond quickly, in the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., and can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.
The power drive unit first rectifies the input three-phase electricity or mains power through the three-phase full-bridge rectifier circuit to obtain the corresponding direct current. The three-phase permanent magnet synchronous communication servo motor is driven by the rectified three-phase electricity or mains power, and then the three-phase sinusoidal PWM voltage inverter is used for frequency conversion.

Software or hardware reasons for Mitsubishi PLC crash
1. Hardware
(1) I/O channeling, the PLC automatically detects the I/O fault and enters the STOP mode.
(2) The I/O is damaged, and the program runs to the response signal that needs the I/O, and cannot execute the instruction downward.
(3) Expansion module (functional, such as A/D) ...

How to adjust the jitter phenomenon of Mitsubishi servo motor
(1) Prerequisites
Mitsubishi servo motors are able to improve the inertia of the motor by adjusting the gain, so as to adapt to the load, but the Mitsubishi servo motor is able to improve endlessly. Under normal circumstances, it is considered that it can withstand within 10-15 times of the additional inertia of the motor, and Mitsubishi reducer is required to be added in addition. We know ...

Mitsubishi FX3u interrupts the location command
The main effect of aborting the positioning instruction is that in some machine tools, when we give the abort signal and can walk to the distance we set, for example, if the mechanical structure needs to use the sensor to determine the position to go, you can use the abort positioning instruction to do, when the induction gives the abort.
