NOTE
• When the user group function is used (Pr.160 = "1") or the password function is enabled (with Pr.296 and Pr.297), the easy
setting is disabled (Pr.79 is not displayed).
• "ER2" appears if a setting change is attempted during inverter operation. Turn OFF the start command (the RUN key or STF/
STR signal).
• If the MODE key is pressed before pressing the SET key, the easy setting mode is terminated and the operation panel returns
to the monitor mode. If the easy setting is terminated while Pr.79 = "0 (initial value)", check the inverter operation mode
because the inverter may switch its operation mode between the PU operation mode and the External operation mode.
• Reset by pressing the STOP/RESET key is enabled.
• The following is the frequency commands listed in descending order of priority when "3" is set in Pr.79: Multi-speed setting
function (RL/RM/RH/REX signal) > PID control (X14 signal) > terminal 4 analog input (AU signal) > set frequency (digital input
from the PU).
