The adjustment value can be set according to your need. In the same conditions, if you want to realize
quick protection upon the motor overload, set a small value for P03.23; otherwise, a bigger value shall be
set.
Note
If the rated current of the load motor is not consistent with that of the drive, the motor overload protection can
be realized by setting the function code parameter of P03.23.
0: Disabled
1: Enabled (motor in static status)
Before the auto-tuning, be sure to enter the correct nameplate parameters of the controlled motor. If the
controlled motor is motor 1, input P03.00~P03.04; if the controlled motor is motor 2, input
P03.12~P03.16.
During the static setting of the asynchronous motor, the motor is in static state. The stator resistance (R1),
leakage inductive reactance relative to rated frequency (X) and rotator resistance (R2) of the
asynchronous motor will be automatically measured. The measured parameter values will be
automatically written into P03.06, P03.07 and P03.08 (for motor 2, they will be written into P03.18,
P03.19 and P03.20).
2: Enabled (motor in rotate status)
Before the auto-tuning, be sure to enter the correct nameplate parameters of the controlled motor. If the
controlled motor is motor 1, input P03.00~P03.04; if the controlled motor is motor 2, input
P03.12~P03.16.
During the rotation setting, the asynchronous motor is in static state first. The stator resistance (R1),
leakage inductive reactance relative to rated frequency (X) and rotator resistance (R2) of the
asynchronous motor will be automatically measured. And then the asynchronous motor will turn into the
rotation state, and the mutual inductive reactance (X
m
) and no-load current (I
0
) of the motor will be
automatically measured. The measured parameter values will be automatically written into
P03.06~P03.10 (for motor 2, they will be written into P03.18~P03.22). P03.05 (for motor 2, P03.17) will
be automatically refreshed when the rotation setting is finished.
The set value of P03.24 will be automatically configured as 0 when the auto-tuning is finished.
3: Calculating based on the nameplate parameters (only enabled for asynchronous motor)
This function is only enabled for the asynchronous motor. The drive will automatically calculate
corresponding motor parameters based on the nameplate parameters of the motor set by the user,
and write into P03.06, P03.07, P03.08, P03.09 and P03.10.
Auto-tuning steps of the asynchronous motor:
1) Set the P07.07 torque increase of motor 1 (or P07.16, torque increase of motor 2) as 0.
2) Properly set the function code parameters of P03.00~P03.04 for motor 1 (for motor 2, input parameters
of P03.12~P03.16).
3) Properly set P02.16 (upper limit frequency). The set value of P02.16 shall not be lower than the rated
frequency.
