Select the PU operation mode when applying start and
frequency command by only the key operation of the
operation panel (FR-PU04/FR-PU07). Also select the PU
operation mode when making communication using the PU
connector.
When "1" is selected for Pr. 79, the inverter enters the PU
operation mode at power ON. You cannot change to the
other operation mode.
The setting dial of the operation panel can be used for
setting like a potentiometer. (Refer to Pr. 161 Frequency
setting/key lock operation selection (page 273))
Select the External operation mode when the start
command and the frequency command are applied
from a frequency setting potentiometer, start switch, etc.
which are provided externally and connecting them to
the control circuit terminals of the inverter.
Generally, parameter change cannot be performed from
the operation panel in the External operation mode.
(Some parameters can be changed. Refer to the
detailed description of each parameter.)
When "0" or "2" is selected for Pr. 79, the inverter enters
the External operation mode at power-ON. (When using
the Network operation mode, refer to page 204.)
When parameter changing is seldom necessary, setting
"2" fixes the operation mode to the External operation
mode.
When frequent parameter changing is necessary,
setting "0" (initial value) allows the operation mode to be
changed easily to the PU operation mode by pressing
of the operation panel. When you switched to the
PU operation mode, always return to the External
operation mode.
The STF and STR signal are used as a start command,
and the voltage or current signal to terminal 2, 4, multi-
speed signal, JOG signal, etc. are used as a frequency
command.
