Selection of operation mode and
⋅ Select the external operation mode when performing
operation by providing
potentiometer, start switch, etc. externally and
connecting them to the control circuit terminals of
the inverter.
⋅ Basically, parameter changing is disabled in external
operation mode. (Some
changed. Refer to page 38 for the parameter list.)
⋅ 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 150.)
⋅ When parameter changing is seldom necessary,
setting "2" fixes the operation mode to external
operation mode. When frequent parameter changing
is necessary, setting "0" (initial value) allows the
operation mode to be changed easily to PU
operation mode by pressing
panel. When you switched to PU operation mode,
always return to external operation mode.
⋅ The STF and STR signal are used as a start
command, and the terminal 2, 4, multi-speed setting,
JOG signal, etc. are used as frequency setting.
⋅ Select the PU operation mode when performing
operation by only the key operation of the operation
panel (FR-DU07) or parameter unit (FR-PU04). 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 volume. (Pr. 161 Frequency setting/key
lock operation selection, refer to page 217.)
