Description

Technical Field

[0001] This utility model relates to the field of servo motor control technology, and in particular to a servo fault braking control system. Background Technology

[0002] Servo drives, as drive control units in industrial automation and robotics, are the foundation of the entire motion control system. Because the permanent magnet servo motor controlled by the servo drive can transmit energy back to the servo drive through the driven object during different load characteristics, braking, or deceleration, this increased interference can lead to servo drive failure. In such cases, the servo drive cannot effectively control the servo motor for braking, resulting in safety accidents or product quality defects. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a servo fault braking control system that can apply a brake to the servo motor when the servo driver fails, thereby preventing safety accidents or avoiding product quality defects.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows:

[0005] A servo fault braking control system includes a control board. The control board is equipped with a pull-in coil, a control switch, and a light-emitting diode (LED). The pull-in coil has a first pin and a second pin connected to its two ends, respectively. The first and second pins are connected to the CN1 port of a servo driver. The control switch is located on one side of the pull-in coil and is a normally closed switch. One end of the control switch is connected to a third pin, and the other end is connected to a fourth pin and a resistor. The third pin is connected to one end of a constant voltage source. The other end of the resistor is connected to the LED. The other end of the LED is connected to a fifth pin and a sixth pin. The fourth and fifth pins are connected to the brake coil of a servo motor, and the sixth pin is connected to the other end of the constant voltage source or grounded.

[0006] When the servo driver is working normally, no current flows through the pull-in coil, the control switch is closed, and the fourth and fifth pins output the working voltage. One end of the brake coil of the servo motor is connected to a constant voltage source of +24V, and the other end is connected to 0V. When the brake coil is energized, the motor spindle is released, the servo motor is in normal operation, and the LED is lit.

[0007] When the servo driver alarms due to a fault, the coil is energized and generates magnetism. At this time, the coil will exert an attractive force on the control switch, causing the control switch to be in the off state. The fourth and fifth pins will output no working voltage, the brake will lock the motor spindle, the LED will be in the off state, and the servo motor will be in the braking state.

[0008] As a further improvement of this invention, the output value of the constant voltage source is 24V.

[0009] As a further improvement of this utility model, the servo motor is a Delta AC servo system ASDA-A2 series.

[0010] The beneficial effects of this invention are: it can brake the servo motor when the servo driver fails, thereby preventing safety accidents. When the servo driver is working normally, no current flows through the coil, the control switch is closed, the fourth and fifth pins output working voltage, the servo motor is in normal operation, and the LED is lit. When the servo driver alarms, the coil is energized and generates magnetism. At this time, the coil exerts an attractive force on the control switch, causing the control switch to be in the open state. The fourth and fifth pins output no working voltage, the LED is off, and the servo motor is braked. Attached Figure Description
