Parameters (D) Operation command and frequency command
FR-A800 5 - 267
PU operation mode (Pr. 79 = "1")
●
Select the PU operation mode when applying start and frequency commands by only the key
operation of the operation panel or the parameter unit. Also select the PU operation mode when
making communication using the PU connector.
●
When Pr. 79 = "1", the inverter starts up in the PU operation mode at power-ON. The mode cannot
be changed to other operation modes.
●
The setting dial of the operation panel can be used for setting like a potentiometer. (Pr. 161
"Frequency setting/key lock operation selection" page 5-198)
●
When the PU operation mode is selected, the PU operation mode signal (PU) can be output.
For the terminal used for the PU signal, set "10 (positive logic)" or "110 (negative logic)" in any of
Pr. 190 to Pr. 196 (output terminal function selection) to assign the function.
PU/External combined operation mode 1 (Pr. 79 = "3")
●
Select the PU/External combined operation mode 1 when applying a frequency command from
the operation panel or the parameter unit and inputting a start command with the external start
switches.
●
Set "3" in Pr. 79. The mode cannot be changed to other operation modes.
●
When a frequency is input from the external signal by multi-speed setting, it has a higher priority
than the frequency command from the PU. Also, when AU is set to "ON", the command signal is
output to the terminal 4.
