Product Introduction:
B00307-NBA is the ordering base for an AKD servo drive rated 3 A continuous, 240 VAC class, with no display, standard I/O, no fieldbus card. The “NBA” in AKD context means: N = no regen resistor built in, B = basic I/O, A = Americas/240 VAC line filter variant. Often sold as spare board set or drive core.
