Speed estimation
Ambient conditions
Motor type Induction motor (IM), Permanent magnet motor (PM),
Synchronous reluctance motor (SynRM), DC motor
Motor control mode FSO can be used in Direct Torque Control (DTC) or scalar
mode.
Speed range Allowed range depends on the used motor.
Maximum range: (-35880…+35880 rpm)/(number of motor pole
pairs).
Accuracy The speed estimation error is ± motor slip.
There can also be estimation ripples at the zero speed region
(below 2 Hz / 3% of the nominal speed). For more information,
see section Safe speed estimate on page 44.
Operational frequency Drive output up to 598 Hz
