Chapter 6 - Parameter Description [I/O]
6-37
The following table shows the selection in I/O-48.
Setting Range

Description
None
0
Continuous operating after loss of
frequency reference.
FreeRun
1
Inverter cuts off its output after
determining loss of frequency reference.
Stop
2
Inverter stops by its Decel pattern and
Decel time after determining loss of
frequency reference.
I/O-49 [Time out] sets the waiting time before determining
the loss of reference signal. Inverter waits to determine the
loss of a reference signal until times out.
☞
Note: I/O-48 and I/O-49 also apply when DRV-04 is set to
‘Keypad-1’ or ‘Keypad-2’ for determining the loss of
command frequency.

Multi-function input terminals can be defined for many
different applications. The following table shows the
various definitions for them.

[Speed-L, Speed-M, Speed-H]
By setting P1, P2, P3 terminals to ‘Speed-L’, ‘Speed-M’
and ‘Speed-H’ respectively, inverter can operate at the
preset frequency set in DRV-05 ~ DRV-07 and I/O-20 ~
I/O-24.
The step frequencies are determined by the combination of
P1, P2 and P3 terminals as shown in the following table.
