The RT signal acts as the second function selection signal and makes the other second
functions valid. (Refer to section 6.10.3.)
The amount of current flows in the motor may become large according to the conditions
such as the motor characteristics, load, acceleration/deceleration time, wiring length, etc.,
resulting in an overcurrent trip (OL (overcurrent alarm) then E.OC1 (overcurrent trip during
acceleration), overload trip (E.THM (motor overload trip), or E.THT (inverter overload trip).
(When a fault occurs, release the start command, and decrease the Pr. 0 setting 1% by 1%
The Pr. 0, Pr. 46 settings are valid only when V/f control is selected.
When using the inverter dedicated motor (constant torque motor) with the FR-E740-120 and
170, set torque boost value to 2%. When Pr. 0 = 3% (initial value), if Pr. 71 value is changed
to the setting for use with a constant-torque motor, the Pr. 0 setting changes to 2%.
Changing the terminal assignment using Pr. 178 to Pr. 189 "Input terminal function selec-
tion" may affect the other functions. Please make setting after confirming the function of
