• Setting "10 to 17" in Pr.73 Analog input selection enables the polarity reversible operation of the main speed command to
which PID manipulated amount added. (Polarity reversible operation of the main speed command without addition is not
possible.)
• When the polarity reversible operation is enabled, the integral term cannot be limited by the maximum and minimum frequency
when Pr.1015 Integral stop selection at limited frequency = "0 or 10".

Checking of current input on analog input terminal
A terminal for current input check can be selected.
 Selection terminal for current input check (Pr.573)
• Use Pr.573 to select which terminal's current input is checked.
5
Input terminal status monitor
The input states of terminals S1 and S2 can be monitored.
 Monitor item list (Pr.52, Pr.774 to Pr.776, Pr.992)
• Use Pr.52, Pr.774 to Pr.776, or Pr.992 to select the item to monitor on the operation panel or the parameter unit.
• Refer to the following table to find the setting value for each monitoring. The value in the Pr. setting column is set in each of the
parameters for monitoring ( Pr.52, Pr.774 to Pr.776, and Pr.992 ) to determine the monitor item. The value in the RS-485 column
is used for the RS-485 communication special monitor selection. The value in the MODBUS RTU column is used for the
MODBUS RTU real time monitor.
*1 The details of bits for the input terminal status are as follows. (1: ON state, 0: OFF state of a terminal on the inverter. " ─ " denotes an
indefinite (null) value.)
*2 Parameter setting is not available for setting the item as the main monitor item on the LCD operation panel (FR-LU08) or the
parameter unit (FR-PU07). Use the monitor function of the FR-LU08 or the FR-PU07 for setting.

4 mA input fault (E.LCI) is activated when the current input loss is
detected.

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, 14 , 24 Operation continues at the frequency set in Pr.777 .
9999 No current input check.
