key to enter Programming mode. The menu for function selection will be dis-
played.
(2) With the menu displayed, use the

3_09
Load shaft
speed
(line speed)
r/min
(m/min)
The unit for load shaft speed is r/min and that for line speed is
m/min.
Display value = (Output frequency Hz before slip compensation)
× (Function code E50)
appears for 10000 (r/min or m/min) or more. When
appears, decrease function code E52 data so that the LED
monitor displays 9999 or below, referring to the above equation.
3_10
PID process
command
N/A
The command is displayed through the use of function code E40
and E41 data (PID display coefficients A and B).
Display value = (PID process command) × (Coefficient A - B) + B
If PID control is disabled, "– – – –" appears.
3_11
PID feedback
amount
N/A
This value is displayed through the use of function code E40
data and function code E41 data (PID display coefficients A and
B).
Display value = (PID feedback amount) × (Coefficient A - B) + B
If PID control is disabled, "– – – –" appears.
