Chap. 9 FUNCTION CODES
E39 Coefficient for Constant Feeding Rate Time Refer to E50.
E39 and E50 set a coefficient to be used for setting the constant feeding rate time, load shaft
speed or line speed and for displaying its output status.
Data setting ranges and calculation equations
- Data setting range for E39: 0.000 to 9.999
for E50: 0.01 to 200.00

Load Shaft Speed = (E50: Coeff. for Speed Indication) u Frequency (Hz)
Line Speed = (E50: Coeff. for Speed Indication)
u Frequency (Hz)
Where, Freq. is the set frequency if each expression is for one of the set data for the constant
feeding rate time, load shaft speed, or line speed; it is the output frequency if each expression is
for the output status monitor.
If the constant feeding rate time is 999.9 min or more, or the denominator on the right in the first
equation is 0, then the number 999.9 will be displayed.
E40 PID Display Coefficient A
E41 PID Display Coefficient B
E40 or E41 sets the conversion factor to equal an indicated value (process amount) with the
target and feedback values in PID control.
- Data setting range: -999 to 0.00 to 999 for conversion factors A and B.
Data setting and operation
Target (commanded) and feedback values in PID control
Set the maximum and minimum PID indication values to function code E40 (factor A) and E41
(factor B), respectively. Calculate the indication value using the equation below.
Indication value = (Target or feedback value) x (Factor A - B) + B
E43 Monitor Item Selection
Selects the monitoring item to be displayed on the LED monitor. When turning ON power to
the inverter or after changing function code E43, the inverter will indicate the selected item on
the LED monitor.
