What is the motor series parameter setting of the inverter? If it is with the spindle,
Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
The motor series setting of the inverter should be set according to the series of motor
The number of motor poles can be estimated by the parameters:
1000Hz corresponds to 60000rpm,
According to "Speed in rpm = 60 * Frequency in Hz / (Number of Poles / 2)",
Number of poles = 60 * Frequency indicated by Hz * 2 / Speed in rpm = 60 * 1000 * 2/60000 = 2 poles.
The same is true with 333Hz and 20000rpm projections.
The number of motor poles for the frequency converter should be entered with the number of poles of the motor that are directly connected to the frequency converter.
