Parameter
PU operation mode (Pr. 79 = 1)
Select the PU operation mode when performing operation by only the key operation of the op-
eration panel (FR-DU07) or parameter unit (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 can-
not 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 section 6.22.2.)
When PU operation mode is selected, the PU operation mode signal (PU) can be output. For the
terminal used for the PU signal output, assign the function by setting "10 (source logic) or 110
(sink logic)" in any of Pr. 190 to Pr. 196 "output terminal function selection".
PU/external combined operation mode 1 (Pr. 79 = 3)
Select the PU/external combined operation mode 1 when making frequency setting from the op-
eration panel FR-DU07 (digital dial) or parameter unit FR-PU04/FR-PU07 and inputting the start
command with the external start switch.
Select "3" for Pr. 79. You cannot change to the other operation mode by using the PU/EXT-key.
When a frequency is input from the external signal by multi-speed setting, it has a higher priority
than the frequency setting of the PU. When AU is on, the terminal 4 is used.
