The invention discloses a testing method and testing equipment of a digital interface circuit of a servo drive. The method comprises the steps that a level of a first base pin of the servo drive and a level of a second base pin of the testing equipment of the digital interface circuit of the servo drive are detected; whether the levels of the first base pin and the second base pin are high levels is determined; when the levels of both the first base pin and the second base pin are determined to be the high levels, the digital interface circuit of the servo drive can be deemed to be normal; and when the level (s) of the first base pin and / or the level of the second base pin are / is determined to be the low level (s), the digital interface circuit of the servo drive can be deemed to be abnormal. The testing method and the testing equipment of the digital interface circuit of the servo drive disclosed by the invention solve the technical problem in the prior art that the digital interface circuit of the servo drive cannot be tested separately.
Description
technical field [0001] The invention relates to the field of testing, in particular to a testing method and testing equipment for a digital interface circuit of a servo driver. Background technique [0002] In some developed countries, the servo system has become a separate system. Some companies with relatively early development have already established their own servo drive design and production systems and servo motor production systems, and their production capacity is very strong. own test system. [0003] In China, due to technical and market share reasons, it is impossible to require customers to use servo products from the same company for building systems. Therefore, domestic products must use independent testing equipment to independently test the performance of each part of the servo system. At present, relevant Technology cannot test the digital interface circuit of the servo drive alone. [0004] For the above problems, no effective solution has been proposed ...
