0: No autotune
1: Non-rotating static autotune
2: Rotating autotune
The motor must be at a standstill before a non-rotating autotune is initiated.
The motor must be at a standstill and unloaded before a rotating autotune is initiated.
Enter the motor rated frequency (taken from the motor name plate).
Defines the voltage to frequency ratio applied to the motor.
Auto: Automatically calculates the number of motor poles from the settings of Pr 07 and Pr 39
2P: Set for a 2 pole motor
4P: Set for a 4 pole motor
6P: Set for a 6 pole motor
8P: Set for an 8 pole motor
Ur S: Stator resistance is measured each time the drive is enabled and run
Ur: No measurement is taken
Fd: Fixed boost
Ur A: Stator resistance is measured the first time the drive is enabled and run
Ur I: Stator resistance measured at each power-up when the drive is enabled and run
SrE: Square law characteristic
In all Ur modes, the drive operates in open loop vector mode.
