LCD Display Description
Tuning
Time
Set the auto-tuning type to “Standstill”. -
Auto-tuning starts if ALL1 is set. -
Stator resistance (Rs) is measured without
rotating the motor.
20-30 Sec
The leakage inductance (sL) of the motor is
measured without rotating the motor.
90-150 Sec
Flux current (IF), rotor time constant (τr) and
stator self-inductance (Ls) is measured
simultaneously without rotating the motor.
40-70 Sec
When auto-tuning is complete successfully,
“None” is displayed. If error occurs during auto-
tuning, “[][] Error” is displayed. In this case,
verify motor parameters and encoder setting is
done properly and redo the auto-tuning. If the
problem persists, contact LS representative.
