Cause : Speed setpoint filter natural frequency > Shannon frequency comes when the natural filter frequency of the speed setpoint filter (p1417) is greater than or equal to the Shannon frequency. The Shannon frequency is calculated according to the following formula: 0.5 / p4099[3].

  • Reduce the natural frequency of the speed setpoint filter (PT2 low pass) (p1417).
