Parameter Frequency setting by analog input (terminal 2, 4)
FR-E700 SC EC/ENE 6 - 185
There are three methods to adjust the frequency setting voltage (current) bias/gain:
●
Method to adjust any point by application of voltage (current) to across the terminals 2-5 (4-5).
(Refer to page 6-187.)
●
Method to adjust any point without application of a voltage (current) to across terminals 2-5 (4-5).
(Refer to page 6-188.)
●
Adjusting only the frequency without adjusting the voltage (current).
(Refer to page 6-189.)

NOTE
When voltage/current input signal for terminal 4 was switched using Pr. 267 and voltage/current
input switch, perform calibration without fail.
