Product Description:

The PB2D003R1U0 is a dual-axis servo driver supplied by Sanyo Denki within the PB SANMOTION Servo Drivers series. Designed for compact machine modules, it conditions DC power and serial command data to regulate low-voltage servo motors used in pick-and-place heads, indexing tables, and miniature conveyors. By handling position, velocity, and torque loops in one enclosure, the unit simplifies wiring between the motion controller and the actuators.

The driver exchanges motion commands over an RS-485 2-wire half-duplex interface, allowing multidrop networks without separate clock lines. Motor phases are energized through PWM control, so current is modulated with fine resolution while switching loss remains low. The main bus accepts 24 or 36 VDC ±10%, making it suitable for battery-backed or low-voltage control panels. At full load, each axis draws up to 3.5 A per axis, which helps with power supply and conductor sizing. The rated ambient temperature range is 0 to 55 °C, permitting installation inside machines that lack active cooling. Closed-loop velocity commands can be executed from standstill up to 4500 rpm, covering typical light-duty servo applications.

Position resolution is table-driven, and the internal buffer stores 256 addressable points for indexed moves or repetitive patterns. The electronics are housed in a 120 × 55 × 80 mm case, so two axes of amplification fit in a DIN-rail bay normally occupied by a single conventional drive. Mechanical reliability is supported by a vibration tolerance of 0.5 G. Data integrity is maintained when ambient humidity remains below 90% RH without condensation. Start-stop synchronization aligns multiple drivers over the serial link, while the single-power architecture reduces wiring by eliminating separate control-logic supplies. The permitted storage temperature ranges from -20 to 70 °C, protecting the unit while it is kept in inventory or transported.
