[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.
