• When the inverter is driven by an external analog frequency command sources (terminals [12],
[C1], and [V2]):
The "Switch normal/inverse operation" command (IVS) can apply only to the analog frequency
command sources (terminals [12], [C1] and [V2]) in frequency command 1 (F01) and does not
affect frequency command 2 (C30) or UP/DOWN control.
As listed below, the combination of the "Selection of normal/inverse operation for frequency
command 1" (C53) and "Switch normal/inverse operation" (IVS) determines the final operation.
Combination of C53 and (IVS)
Data for C53
(IVS) Final operation
OFF Normal
0: Normal operation
ON Inverse
OFF Inverse
1: Inverse operation
ON Normal
Interlock -- (IL)
(Function code data = 22)
In a configuration where a magnetic contactor (MC) is installed in the power output (secondary)
circuit of the inverter, the momentary power failure detection feature provided inside the inverter
may not be able to accurately detect a momentary power failure by itself. Using a digital signal
input with the interlock command (IL) assures the accurate detection
(IL) Meaning
OFF No momentary power failure has occurred.
ON
A momentary power failure has occurred.
(Restart after a momentary power failure enabled)
For details of operation after a recovery from momentary power failure, refer to the
description of function code F14.
Enable communications link via RS-485 or field bus (option) -- (LE)
(Function code data = 24)
Turning this terminal command ON assigns priorities to frequency commands or run commands
received via the RS-485 communications link (H30) or the field bus option (y98).
No (LE) assignment is functionally equivalent to the (LE) being ON.
For details of switching, refer to H30 (Communications link function) and y98 (Bus link
function.
