Parameter Frequency setting by analog input (terminal 2, 4)
FR-E700 SC EC/ENE 6 - 181
Perform operation by analog input current
When the pressure or temperature is controlled constant by a fan, pump, etc., automatic operation can
be performed by inputting the output signal 0/4 to 20 mA of the adjuster to across the terminals 4-5.
Perform forward/reverse rotation by analog input (polarity reversible operation)
Setting "10" or "11" in Pr. 73 and adjusting Pr. 125 (Pr. 126) "Terminal 2 frequency setting gain fre-
quency" (Terminal 4 frequency setting gain frequency) and C2 (Pr. 902) "Terminal 2 frequency setting
bias frequency" to C7 (Pr. 905) "Terminal 4 frequency setting gain" makes reverse operation by ter-
minal 2 (terminal 4) valid.
NOTE
The AU signal must be turned on to use the terminal 4. For the terminal used for AU signal input,
set "4" in any of Pr. 178 to Pr. 184 "Input terminal function selection" to assign the function.

Example
쑴
When performing reversible operation by terminal 2 (0 to 5 V) input.
햲
Set "11" in Pr. 73 to make reversible operation valid.
Set frequency at maximum analog input in Pr. 125 (Pr. 903).
햳
Set 1/2 of the value set in C4 (Pr. 903) in C3 (Pr. 902).
햴
Reversible operation is performed when 0 to 2.5 V DC is input and forward rotation when 2.5 to
5 V DC.

P
CAUTION:
When reversible operation is set, be aware of reverse rotation operation when analog input
stops (only the start signal is input).
NOTE
When reversible operation is valid, reversible operation (0 to 4 mA: reverse operation, 4 mA to
20 mA: forward operation) is performed by terminal 4 in the initial setting.
