4.5.2 Rotational auto-tuning
1) Precautions
CAUTION
Be sure to remove the load connected to the motor shaft before performing rotational auto-tuning.
Otherwise, it may lead to damage to the motor or bodily injury. DB resistor should be installed because the
inverter repeats abrupt Accel/Decel many times to find the motor constant (Tr) during tuning.
2) 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 1500 rpm
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 1500 rpm.
30 ~ 60(Sec)
Stator self-inductance (Ls) is measured
by rotating the motor at 1500 rpm.
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.
