    7. MODBUS 7.1 Protocol The master controls communication between master and slave. A typical message consists of a request (query message) sent from the master followed by an answer (response message) from the slave. When master begins data transmission, a set of data is sent to the slave in a fixed sequence. When it is received, the slave decodes it, takes the necessary action, and returns data to the master.

  • Page 181: Display Scale

    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.

  • Page 182: Measuring Method

    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 185 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.
  • Page 186 8. FUNCTIONS Control response parameters This is the function of enabling the setting of response to set value change in select any one of 3 steps (Slow, Medium, Fast) in PID control. In order to achieve faster controlled object response to set value change, select Fast. However, slight overshoot is unavoidable when selecting Fast.

  • Page 189: Output Change Rate Limiter

    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.

    8. FUNCTIONS 8.2.8 Alarm hold function In the alarm hold function, the alarm function is kept invalid even if the motor speed measured value is in the alarm range when the power is on or the operation mode is switched to RUN from STOP. The alarm function is held until it passes with H-SIO-A alarm hold cancel time.

    8. FUNCTIONS 8.2.9 Assignment of channels Channel number of H-SIO-A modules uses the same kind of channel number as H-TIO- modules and H-CIO-A modules. If the H-SIO-A modules are mounted together with H-TIO- modules and H-CIO-A modules, the channel numbers are continued. Channel number is decided in order automatically from the left.
