Speed estimation
Ambient conditions
Speed range Allowed range depends on the used motor.
Maximum range: (-30000…+30000 rpm)/(number of motor pole
pairs).
Accuracy The speed estimation error is ± motor slip.
With synchronous motors, there can be small estimation ripples
at the zero speed region (below 10 rpm).
Operational frequency Drive output up to 500 Hz
