Lab 10e Flying Start

Using the same motor parameters and PI parameters as Lab10a, almost all parameters are set the same, why Lab10a can start smoothly and run normally at 200~2000rpm, but Lab 10e cannot start smoothly and only run normally after shaking for a few seconds, why? Which parameters should be modified to solve the smooth startup problem of Lab 10e?
