AKD2G安全制动能量计算器
以下展示的是停机时间与制动电流的曲线图。在曲线图下方，是生成这些曲线所依据的信息及假设的汇总，同时给出了您 2G 运动系统安全动态制动器所需继电器和电阻器组件的额定参数要求。有关安全动态制动器组件的安装与设置信息，请参阅相应的 AKD2G 安装手册。
AKD2G 安全动态制动计算器是一款工具，可帮助您在使用 AKD2G 的安全动态制动器（SDB）功能时确定电机的停机时间。在某些应用场景中，通过“安全”继电器将电机线短接，会比使用机电式保持制动器更为有利。除了停机时间外，该计算器还会为您提供制动电流方面的信息，以便您确定 SDB 电路中接触器和电阻器的额定参数。
有关 SDB 功能的详细信息及接线示例，请参阅 AKD2G-S 安装手册中的安全手册部分。

Overview
The AKD2G Safe Dynamic Braking calculator is a tool that will assist you in determining the Stopping Time for the motor when using the AKD2G’s Safe Dynamic Brake (SDB) function. In some applications, it will be very beneficial to short the motor wires via “Safe” relays rather than using an electromechanical holding brake. In addition to the Stopping Time the calculator will provide you information on the Braking Current for the purpose of determining contactor and resistor ratings in the SDB circuit.
Please refer to AKD2G-S Installation Manual, Safety Manual section for details and wiring examples associated with the SDB function.
Prerequisite Information
To use the AKD2G Safe Dynamic Braking calculator you will need to know which AKM2G motor model you will be using, whether the motor will have a built-in holding brake, the estimated inertia mismatch ( the ratio of the inertia between the motor and the load), the load friction, and the dynamic braking speed (the speed of the motor when the dynamic braking is engaged). Note that the dynamic braking speed cannot exceed the motors maximum rated speed.
Executing the Calculation
Using the Prerequisite Information you gathered enter the motor, whether there is a brake, the inertia mismatch, the load friction and the dynamic braking speed using the dropdown or direct data entry as indicated for each field.
Then select three external resistance values to plot.
When you have verified that you have all the information entered correctly click the “Calculate” button.
A dialog box will appear that shows the tool is making the calculation. The time to complete the calculation can depend on your system, connection and your selected external resistances.
The Results
When the calculation completes the upper plot will show the Stopping Time for the selected resistance values. The lower plot will show the Braking Current for the selected resistance values.
Below the plots you will find a summary of the assumptions used for the calculated results and a tabular listing of the result information including the minimum braking contactor rating and minimum braking resistor ratings for your selected external resistance values.
You may click the “Contact a Safe Dynamic Braking Expert” to reach a Kollmorgen Support expert to assist you with your application. You may also click the “Share Results” to produce an image file of your results to share with others.
You can repeat the steps as many times as needed to see the different possible stopping times and braking currents based on different external resistance values.
| @External Resistance | Est. Stopping Time [ms] | Min. Braking Contactor Ratings | Min. Braking Resistor Ratings | |
|---|---|---|---|---|
| Braking Current [Arms] | Braking Current [Arms] | Braking Power [Watts] | ||
注意-AKD2G 安全动态制动功能是相关 AKD2G 文档中所述的 AKD2G 安全运动（SafeMotion）功能的一部分。安全动态制动功能的运行取决于用户在计算器中输入的准确数据、正确的安装以及该功能的恰当应用/使用。若出现不当条件，可能会导致电机永久性损坏（退磁），且无法修复。
