[0048] Braking unit 3 is voltage triggered. The control circuit of braking unit 3 detects the bus voltage in real time. When the bus voltage reaches the set starting voltage (this voltage value can be set), braking unit 3 connects the circuit and braking resistor 2 starts working. Braking resistor 2 uses air-cooled corrugated resistors, and uses several resistors to dissipate heat at the same time. In order to ensure that the braking resistor can work stably for a long time, the heat generated is dissipated by the equipped cooling fan. When the bus voltage drops to the set braking stop voltage (this voltage value can also be set), the braking unit stops working.

[0049] The control panel 20 realizes comprehensive control of the machine equipment, wherein the inverter panel is connected to the motor controller to adjust the motor setting parameters. When the motor connection interface is connected to different types of motors, the motor and the motor controller can be matched and calibrated.

[0050] The control cable interface 17 multi-core plug-in can support different protocol communication control such as CAN, 485, etc. The sensor parameters of the external execution unit enter the microcomputer control unit through the plugged cable to form a closed-loop control.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
