5.9.7 Checking of current input on analog input terminal
When current is input to the analog input terminal 2 and terminal 4, operation when the current input has gone below the
specified level (loss of analog current input) can be selected. It is possible to continue the operation even when the analog
current input is lost.

1 Operation continues with output frequency
before the current input loss.
2 4 mA input fault (E.LCI) is activated when the
current input loss is detected.
3 The inverter output decelerates the motor to a
stop when the current input loss is detected.
After the motor is stopped, 4 mA input fault
(E.LCI) is activated.
4 Operation continues at the frequency set in
Pr.777.
11 Operation continues at the output frequency
before the current input loss.
12 4 mA input fault (E.LCI) is activated when the
current input loss is detected.
13 The inverter output decelerates the motor to a
stop when the current input loss is detected.
After the motor is stopped, 4 mA input fault
(E.LCI) is activated.
14 Operation continues at the frequency set in
Pr.777.
21 Operation continues at the output frequency
