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.

I/O-13: Multi-function Input Terminal ‘P2’ Define
I/O-14: Multi-function Input Terminal ‘P3’ Define
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.

☞ I/O-20 [Jog Frequency] can be used as one of the step
frequencies.
☞ If the ‘Jog’ terminal is ON, inverter operates to Jog frequency
regardless of other terminal inputs.
