The Number of Trials parameter limits how many automatic resets can occur within a trial period defined by 3102 TRIAL TIME. The manual's first action is: “• If the number of automatic resets exceeds this limit (within the trial time), the drive prevents additional automatic resets and remains stopped. • Starting then requires a successful reset performed from the control panel or from a source selected by 1604 FAULT RESET SEL.”
