  - Offers local/remote control priority selection to adapt to different operational scenarios.

2、 Classification of Drivers

1. Classified by energy conversion method: Drivers can be divided into electric drivers, hydraulic drivers, pneumatic drivers, etc.

2. Classified by motion mode: Drivers can be divided into linear motion drivers, rotary motion drivers, swing motion drivers, etc.

3. Classified by control method: Drivers can be divided into open-loop drivers, closed-loop drivers, semi closed-loop drivers, etc.

4. Classified by function: Drivers can be divided into positioning drivers, speed regulating drivers, synchronous drivers, etc.

3、 The working principle of the driver

1. Electric drive: The electric drive converts electrical energy into mechanical energy through an electric motor to achieve the operation

of mechanical equipment. The working principle of electric motors mainly includes DC motors, AC motors, stepper motors, servo motors, etc.

2. Hydraulic Drive: Hydraulic drives convert hydraulic pressure energy into mechanical energy through hydraulic pumps, enabling the

operation of mechanical equipment. The working principle of hydraulic actuators includes the collaborative work of components such as

hydraulic pumps, hydraulic cylinders, and hydraulic valves.

3. Pneumatic actuator: Pneumatic actuators convert gas pressure energy into mechanical energy through pneumatic components to achieve

the operation of mechanical equipment. The working principle of pneumatic actuators includes the coordinated operation of components such as pneumatic cylinders, pneumatic valves, and air sources.
