Automatic frequency setting / key lock operation
selection
Turing the setting dial or pressing the UP/DOWN key on the operation panel enables frequency setting without pressing the
SET key.
The key operation of the operation panel can be disabled.

 Automatic frequency setting (Pr.161 = "1 or 11")
• To set the frequency using the operation panel when Pr.161 = "0" (initial value) or "10", change the frequency value using
the setting dial or the UP/DOWN key, and press the SET key to confirm the setting (the value is stored in the RAM and
EEPROM).
• When Pr.161 = "1 or 11", the automatic frequency setting is enabled. After the frequency value is changed using the setting
dial or the UP/DOWN key, the value indicated is stored in the RAM. If the frequency value has not been changed for 10
seconds, the value is stored in the EEPROM.
When the automatic frequency setting is disabled (Pr.161 = "0 (initial value) or 10")
When the MODE key is pressed or after 5 seconds
When the automatic frequency setting is enabled (Pr.161 = "1 or 11")
NOTE
• If the operation panel does not have the operation command source (Pr.551 = "2, 3, or 9999" (with USB and/or PU
connection)), the frequency cannot be set using the operation panel.
• If the operation mode is changed to one in which the inverter does not operate according to the frequency set on the operation
panel after the frequency value is stored in the RAM but before it is stored in the EEPROM, the value is not stored in the
EEPROM.
• If the power is OFF or the inverter is reset after the frequency value is stored in the RAM but before it is stored in the EEPROM,
the value is not stored in the EEPROM.
• When setting the frequency by turning the setting dial, the frequency goes up to the set value of Pr.1 Maximum frequency.
Be aware of what frequency Pr.1 is set to, and adjust the setting of Pr.1 according to the application.
