    8. FUNCTIONS 8.2.1 Display scale This function scales the display range of the input value between 9999 to 10000. However, the maximum span is 10000. H-SIO-A input frequency at full scale: Sets the frequency of encoder when display scale high value (full scale) is displayed. Setting rage: 10 to 50000 Hz Display scale high: Sets the high limit value (full scale) of display scale.

    8. FUNCTIONS 8.2.2 Measuring method Can be selected periodic computation method or pulse count method.  Periodic computation method Frequency is obtained by measuring the time required for certain pulse intervals. The number of measured pulses can be set in the pulse range of 1 to 1000 by setting divide ratio. Setting range: H-SIO-A divide ratio: 1 to 1000 Example: When divide ratio is set to 3.

    8. FUNCTIONS 8.2.5 Controls This instrument controls with open loop control or PID control (closed loop control). (1) Open loop control In a deviation between the motor speed measured value and set value is larger than the H-SIO-A control range set value, or the H-SIO-A open/closed loop control transfer is “1: Open loop control,” the instrument is in open loop control, thereby outputting a constant control output value corresponding to the motor speed set value.
  • Page 181 8. FUNCTIONS (2) PID Control (Closed loop control) If a deviation between the motor speed measured value and set value is within the control range set value, and the H-SIO-A open/closed loop control transfer is “0: Closed loop control,” the instrument performs PID control.

    8. FUNCTIONS 8.2.7 Output change rate limiter The output change rate limiter limits the variation of Manipulated output (MV) for a time unit. You can set an output variation, and control the output, when your object requires to avoid sudden variation. The output variation limiter is particularly effective when a sudden variation may cause the controller to crash, or when it may cause a large current.
