Adjust the output torque (current) of the motor
NOTES
The RT signal acts as the second function selection signal and makes the other second
functions valid. (Refer to section 6.9.3.)
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., resul-
ting in an overcurrent trip (OL (overcurrent alarm) then E.OC1 (overcurrent trip during acce-
leration), 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% to
reset.)
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-D740-120SC
and 160SC, 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. 182 "Input terminal function selec-
tion" may affect the other functions. Please make setting after confirming the function of
each terminal.
