Note: When the range of motor parameter auto tuning results is extended, the controls of speed, torque and position and
auto torque increase may become worse. Please change the setting during auto tuning errors of special motors and
motor parameters.

Typical values have been entered for each motor model.
●The setting scope of F5009-F5013 and the minimum values will be changed with the changes of motor capacity set by
F5001.
● When motor test report and other documents with motor constant are used, please enter into the above-mentioned
function code.
● Save the motor constant detected by motor parameter auto tuning (F1001=10, 11) into F5009-F5014
● In vector control, when the inverter output voltage at motor rated speed is lower than motor rated voltage, please
increase the setting of excitation current.
● The preset value of motor stator resistance (F5009) and motor rotator resistance (F5010) turns into resistance by
which temperature conversion was carried out at 75
℃
. Therefore, when you carry out a manual input to a function code,
please set it as 75
℃
with the resistance which carried out temperature conversion.
● In the following states, excitation current decreases automatically from a function code preset value (F5014).
At the time of weak field control (When controlling above motor speed rating)
At the time of energy-saving functional effective (When having set it as F1901=2)
At the time of an instant power failure and an input voltage fall
