• The following is the operation example during External operation.
Output frequency
Analog input
20mA
4mA
STF
LF signal
• The following is the operation example during PID control (reverse action) operation.
Output frequency
20mA
Set point (fixed)
Measured value
4mA
STF signal
LF signal
PID signal
NOTE
• When the setting is changed to the continuous operation (Pr.573 = "1") after the input current loss, the frequency before loss
is regarded as 0 Hz.
 Fault output (Pr.573 = "2")
• When the analog current input becomes 2 mA or lower, the protective function E.LCI (4 mA input fault) is activated and the
output is shut off.
• The following is the operation example during PID control (reverse action) operation.
