Product Description:

The 80SD100XD.C044-01 belongs to the 80SD Stepper Motor Modules series from B & R Automation. It is a compact drive module intended to energize and micro-position two-phase stepper motors used in pick-and-place units, indexing tables, and small conveyor axes within automated lines. By integrating power electronics, encoder evaluation, and brake control in a single housing, the module simplifies panel layouts in distributed machine architectures. It is suited to machines that need compact axis electronics close to the motor without using larger cabinet space for separate drive hardware.

The control section accepts a logic supply of 24 VDC ±25% and dissipates only 8 W maximum, so heat generation inside the cabinet stays low. Motor windings can be driven up to 10 A peak, allowing adequate torque for midsize hybrid steppers, while a nominal switching frequency of 38.5 kHz helps keep current ripple below audible ranges. Positioning accuracy is enhanced by a step resolution of 256 microsteps per full step, and the internal 16-bit counter follows feedback from an ABR single-ended 24 V encoder so missed steps can be detected. During power-up, the inrush current is limited to 10 A to protect upstream 24 V supplies, and a dedicated 24 V brake output permits holding torque when the axis is idle. Motor cables may be routed up to 25 m without derating.

The power stage is buffered by 940 µF of DC-bus capacitance, which helps smooth regenerated energy during rapid deceleration. The module uses an IP20 housing with convection slots and measures 65 mm wide, 95 mm deep, and 134 mm tall, supporting high-density stacking on DIN rails. Cycle synchronization with the higher-level controller can be tightened to a minimum X2X link period of 250 µs, enabling coordinated motion among multiple axes. That arrangement supports synchronized indexing and short move sequences where timing between axes must remain consistent. The protection class requires installation inside an enclosed cabinet, and the compact layout helps keep motor and feedback wiring short.
