5.4 Details of Function Codes
5-156
PID dancer basic position command, display of PID feedback (J01 = 3)
During the dancer control, the PID command value and PID feedback value operate within the ±100% control
range. Therefore, specify the value at +100% of the PID dancer basic position command/feedback value as
PID display coefficient A with E40, and the value at -100% as PID display coefficient B with E41.
Fig. 5.4-70
If the sensor output is unipolar, PID dancer control operates within the range from 0 to +100%. Therefore,
setting the display coefficient B for virtual -100% is necessary.
That is, suppose "b" = "Display value at 0%," then:
Set that
coefficient B = 2b - A.
For details of PID control, see the explanation of the function code J01 or later.
For the displaying method of PID command and PID feedback, see the description of the function code
E43.
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 display various values converted to physical values such as
temperature and pressure.

To set up the analog input monitor, use function codes E61 through E63. Use E43 to choose the item
to be displayed.
E42
Display Filter
E42 specifies a filter time constant to be applied for displaying the various running status monitored on the
keypad except for the speed monitor (E43 = 0). If the display varies unstably due to load fluctuation or other
causes, and it is hard to see the displayed contents, increase the setting.
