  • Page 20 9.4. PWM Feedback Signal PWM feedback signal can provide operation status of the pump, such as power loss or all kinds of alarm/warning modes. PWM feedback signal will feed back exclusive alarming information. If the power voltage detects under voltage signal values, its output signal will be set to 75%. Provided sundries settlement exists in the hydraulic system and causes rotor being blocked, the duty cycle of output signal is set to 90%, the alarm will be given higher priority.
  • Page 21 9.5. How to use the signals The signal can be used to measure power consumption of the pump. The pump signal can be used to detect the actual operating point of the system rather than measuring by the current controlled by the system. The signal is also applicable to comparing velocity setting value and feedback.
