VLT FC 300 - Speed control range (open-loop); Speed control range (closed-loop); Environment

Speed control range (open-loop) 1:100 of synchronous speed
Speed control range (closed-loop) 1:1,000 of synchronous speed
Speed accuracy (open-loop) 30–4,000 rpm: error ±8 rpm
Speed accuracy (closed-loop), depending on resolution of feedback device 0–6,000 rpm: error ±0.15 rpm
Torque control accuracy (speed feedback) max error ±5% of rated torque
All control characteristics are based on a 4-pole asynchronous motor
