2.3) Rotational auto-tuning procedure
LCD display Description
Tuning
time
Set it to “ Rotational ”. -
Auto-tuning starts when it is set to “ ALL1 ”. -
Checks whether the encoder wiring is properly
done and an encoder works well by rotating
the motor at base speed in forward direction.
30~35(Sec)
Stator resistance (Rs) is measured without
rotating the motor.
10~20(Sec)
The leakage inductance (sL) of the motor is
measured without rotating the motor.
5 ~ 20(Sec)
The flux current (IF) is measured by rotating
the motor at base speed.
30~60(Sec)
Stator self-inductance (Ls) is measured by
rotating the motor at base speed.
50~60(Sec)
Accel/Decel is performed repeatedly to find
motor constant (Tr) so that DB Resistor should
be connected before starting tuning.
Otherwise, “Over Voltage ” trip will occur.
20~60(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.
