Fig. 2 The inverter realizes stable control of current and voltage and
will not trigger under any acceleration/deceleration condition
as well as stable operation condition
Large Torque and Stable Operation at Low Frequency under Vector
Control
With precise speed identification and rotor magnetic flux orientation, the torque
responds quickly and stable operation in the case of 0.25Hz load mutation.
Startup torque: Open loop vector control: 0.25Hz; 180% rated torque
Speed stabilization precision: Open loop vector control: ±0.2%
It is especially suitable for:
Medium and large wire-drawing machine, pipe and cable processing, lifting equipment,
rolling mill.
