P0407 – Motor Rated Power Factor
Adjustable 0.50 to 0.99
Range:
Properties: cfg
Access groups MOTOR, STARTUP
via HMI:
Description:
The setting of parameters P0398, P0399, P0401, P0402, P0403, P0404 and P0407 must be according to the
nameplate data of the used motor, taking into account the motor voltage.
P0408 – Self-tuning
Adjustable 0 = Inactive
Range: 1 = No Rotation
Properties: cfg, V V W
Access groups STARTUP
via HMI:
Description:
Parameter P0408 in 1 activates the self-tuning of the V V W mode, where the motor stator resistance is
measured. The self-tuning can only be activated via HMI, and it can be interrupted at any time with the
During the self-tuning, the motor remains still, because a direct current signal is sent to measure the stator
resistance.
If the estimated value of the motor stator resistance is too high for the inverter used (for example: motor not
connected or motor too small for the inverter) the inverter indicates fault F0033.
At the end of the self-tuning process, the measured motor stator resistance is saved in P0409.
P0409 – Stator Resistance
Adjustable 0.01 to 99.99 Ω

MOTOR, STARTUP
via HMI:
Description:
Motor phase stator resistance in ohms (Ω), assuming a star (Y) motor connection.
If the value adjusted in P0409 is too high or too low for the inverter used, the inverter indicates fault F0033. In
order to exit this condition, just perform a reset by using the
factory default value which is equivalent to WEG IV pole standard motor stator resistance with power matched
to the inverter, as per Table 10.1: Characteristics of IV pole WEG standard motors on page
