Pre-excitation, zero-speed control, and servo lock

Pre-excitation is the process to control current while a motor is stopped so that motor torque can be generated immediately. There are two methods for this p... More Details >>

Combination with existing inverters

Since the existing inverters do not have a terminal to connect to the FR-HC, it cannot be connected to them. Use an inverter compatible with the high power f... More Details >>
