应该是没有找到对应的软件手册。D105在提升固件手册当中有清晰的描述,问题出在速度反馈上:
The drive trips on a fault (D105) if the drive is running, and
• the motor is running in a steady state, and the difference between the motor
actual speed (01.01) and the ramped and shaped speed reference (23.02) is
greater than the steady state deviation level for longer than a delay (74.04)
or
• the motor is accelerating or decelerating, and the difference between the motor
actual speed (01.01) and the ramped and shaped speed reference (23.02) is
greater than the ramping state deviation level for longer than a delay (74.04).
在以下情况下,变频器会由于故障而跳闸 (D105):变频器正在运行;
• 电机在稳定状态下运行时,电机实际速度 (01.01) 与斜坡和曲线速度给定值
(23.02) 之间的差距大于稳定状态偏差水平的时间超过延时 (74.04)
或
• 电机加速或减速时,电机实际速度 (01.01) 与斜坡和曲线速度给定值 (23.02) 之间
的差距大于斜坡状态偏差水平的时间超过延时 (74.04)。
