Combined with the HG gearhead, the 42 mm2 motor models, including those equipped with electromagnetic brakes, produce a maximum holding torque ranging from 22 to 35 lb in. The HG gearhead is also available with 28 mm2 motor models to produce a maximum holding torque ranging from 13 to 17 lb in. The series runs open loop under normal conditions and only runs in closed loop when a position deviation of ∆1.8 is seen. The AlphaStep driver uses microstep control (up to 10,000 spr).
