Under a 50% torque limit, if the commanded speed (50 Hz in your example) cannot be achieved without torque exceeding 50%

Pre-excitation is the process to control current while a motor is stopped so that motor torque can be generated immediat

1. Torque control automatically adjust the speed so that the instructed torque value is maintained. This means that the

You cannot reuse the parameter unit (FR-PU01) for the FREQROL-Z series, the parameter unit (FR-PU02) for the FREQROL-A20

The inverter itself does not have a function to detect the rotation angle and change the velocity accordingly. Therefore

Since the torque control accuracy is influenced by change of motor temperature:- Standard product???±5% (at 75 deg C) ±0
