• Display coefficients for PID dancer position command and its feedback (J01 = 3)
Under PID dancer control, the PID command and its feedback operate within the range 100%, so specify the
value at +100% of the PID dancer position command or its feedback as coefficient A with E40, and the value at
-100% as coefficient B with E41.
If the sensor output is unipolar, the PID dancer control operates within the range from 0 to +100%, so virtually
specify the value at -100% as coefficient B.
That is, suppose "b" = "Display value at 0%," then:
Display coefficient B = 2b - A
For details about the PID control, refer to the description of J01 and later.
For the display method of the PID command and its feedback, refer to the description of E43.
• Display coefficient for analog input monitor
By inputting analog signals from various sensors such as temperature sensors in air conditioners to the inverter,
you can monitor the state of peripheral devices via the communications link. By using an appropriate display
coefficient, you can also have various values converted into physical values such as temperature and pressure
before they are displayed.
To set up the analog input monitor, use function codes E61 through E63. Use E43 to choose the item to be
displayed.
E42
LED Display Filter
E42 specifies a filter time constant to be applied for displaying the monitored running status except the speed
monitor (E43 = 0) on the LED monitor on the keypad. If the display fluctuates and is hard to read due to load
fluctuation or other causes, increase this filter time constant.
