用于测试电力驱动器中的安全转矩关断电路的方法和装置
Abstract:
一种用于测试用于电力驱动器的安全转矩关断(STO)功能部件的功能的方法和装置。激活STO功能部件之后，预定义的开关命令被传输到电力驱动器的功率开关。然后响应与该预定义的开关命令确定功率开关的开关状态。最后，至少基于所确定的开关状态确定STO功能部件的功能。
Abstract(English):

A method and apparatus for testing the function of a Safe Torque Off (STO) feature (100) for an electric drive. After activation of the STO feature (110), predefined switching commands are transmitted (122) to power switches of the electric drive (130). Then a switching state of the power switches is determined responsive to the predefined switching commands. Finally, the functionality of the STO feature is determined based at least upon the determined switching states.
