... A fuse should be connected to the power supply line. The rated maximum current of the TB6560AHQ is 3.5 A/phase and that of the TB6560AFG is 2.5 A/phase. Considering those maximum ratings, an appropriate fuse must be selected depending on operating conditions of a motor to be used. Toshiba recommends that a fast-blow fuse be used. ...
