Open loop: <5 ms with nominal torque and <1 ms with
nominal torque with AFE supply
Closed loop: <5 ms with nominal torque and <1 ms with
nominal torque with AFE supply
Open loop: <2% of motor nominal torque up to nomi-
nal speed and <4% of motor nominal torque in the field
weakening area
Closed loop: <2% of motor nominal torque up to nomi-
nal speed and <4% of motor nominal torque in the field
weakening area
Open loop: 5% of motor nominal slip up to motor nom-
inal motor frequency and 10% of motor nominal slip in
the field weakening area
Closed loop: 0.01% static error of nominal speed with en-
coder PPR of 1024 or better
Open loop: 0.2–0.4% s with nominal torque step
Closed loop: 0.1–0.2% s with nominal torque step
