Product Description:
The PB1D001P100 is a micro servo driver produced by Sanyo Denki for the PB SANMOTION Servo Drivers series. It energizes small DC brushless actuators, converts controller commands into phase-commutated current, and supervises rotor feedback to close the motion loop. Typical applications include indexing tables, miniature pick-and-place modules, and light conveyors where compact electronics are preferred. Its slim form factor supports installation inside low-profile equipment racks with limited space for motion-control hardware.
The primary electrical supply for the driver is 24/36/48 VDC with a ±10% tolerance, provided by a regulated bus. Incoming commands enter through a pulse-train interface, so the controller counts received pulses as the target position while the driver multiplies them according to the selected electronic gearing ratio. Continuous current consumption peaks at 1.6 A rms, providing a suitable current range for the two supported motor types, PBM282D*A20 and PBM284D*A20. This current rating also assists with power-supply sizing for the connected axis. The driver uses a built-in regenerative circuit that returns excess kinetic energy to the DC link during deceleration instead of dissipating it through external resistors. Position feedback relies on a 200 P/R incremental encoder mounted on the motor shaft, allowing basic closed-loop accuracy for light-duty axes.
Fine step resolution can be increased through the internal interpolator, which offers 200, 800, 1600, 3200, 6400, or 12800 P/R to match the pulse frequency delivered by the motion controller. Motor field excitation is limited to 1 A, helping prevent thermal overload of the stator windings in compact actuators. The assembly withstands operational vibration up to 0.5 G, and its W120 × H36 × D70 mm profile fits densely packed panels. An open-frame structure supports convection cooling by allowing air to circulate around the internal components. The unit can operate at a maximum relative humidity of 90% when installed in a suitable enclosure. Because the driver draws DC power rather than AC mains power, it can be integrated directly into 24–48 V motion buses without bulky line filters.
