官方故障排除步驟
[Cause of error] The definition of the tooth geometry is incomplete or contradicts itself. The module and number of teeth are necessary for the definition of a gear tooth system according to DIN 3990 (ISO 6336). Outside diameter and tooth height are optional entries. The outside diameter must be greater than the inside diameter. [Error correction] Enter the module and the number of teeth. If there are deviations from DIN 3990 (ISO 6336) then you can define the outside diameter and tooth height. Check the definition of the outside diameter and tooth height. 10/2023 [907]
