Page 19: Pwm Signal Control Mode
9 PWM Signal Control Mode 9.1 Control and Signal 1) Control Principle HSTEPS…-11 series model pump is controlled by modulated LV PWM (Pulse Width Modulation) digital signal, which means that the variance of velocity de- pends on the external input signal. The variance of velocity is one of the func- tions of input control. -
Page 20: Pwm Input Signal
9.3 PWM Input Signal • In area of high duty-cycle PWM signal, when the input signal fluctuates in the critical point, there will be a delay area to prevent frequent stop and start of the pump. • In area of low duty-cycle PWM signal, the pump runs at high velocity for the sake of system safety. -
Page 21: Pwm Feedback Signal
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 volt- age 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. -
