Mitsubishi Electric fr-e700 series, Instruction Manual

Parameter Adjust the output torque (current) of the motor
FR-E700 SC EC/ENE 6 - 37
NOTES
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), over-
load 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-E740-120SC and
170SC, 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 selection" may
affect the other functions. Please make setting after confirming the function of each terminal.
