Parameter Frequency setting by analog input (terminal 2, 4)
FR-E700 SC EC/ENE 6 - 179
Refer to the following table and set Pr. 73 and Pr. 267. The half-tone screened areas indicate the main
speed setting.
The terminal used for the AU signal input, set "4" in Pr. 178 to Pr. 184 "Input terminal function selec-
tion" to assign functions.

Tab. 6-46: Setting of parameter 73 and 267
NOTES Turn the AU signal on to make terminal 4 valid.
Make sure that the parameter and switch settings are the same. Different setting may cause a fault,
failure or malfunction.
Use Pr. 125 (Pr. 126) "Frequency setting gain" to change the maximum output frequency at input
of the maximum output frequency command voltage (current). At this time, the command voltage
(current) need not be input. Also, the acceleration/deceleration time, which is a slope up/down to
the acceleration/deceleration reference frequency, is not affected by the change in Pr. 73 setting.
Changing the terminal assignment using Pr. 178 to Pr. 184 "Input terminal function selection" may
affect the other functions. Make setting after confirming the function of each terminal.
