Product Description:
The PB3D003M200 is a compact DC servo driver manufactured by Sanyo Denki as part of the PB SANMOTION Servo Drivers series. The module supplies power and closed-loop control signals to a matched brushless servo motor, translating host-controller commands into regulated motor current and pulse-width modulation. Used in light material-handling cells, tabletop automation, and battery-powered platforms, it delivers precise speed, position, and torque regulation while occupying only a small section of a control cabinet or robot base.
Motion capability is centered on a single controllable axis, allowing the driver to operate one servo motor without multiplexing. The internal power stage accepts a 24/48 VDC ±10% supply, so it can share the low-voltage rails commonly used in mobile or compact machines. During operation, the driver draws 3 A of main input current, which should be considered when selecting fuses or DC power modules. The aluminum housing measures 160 × 32 × 95 mm and weighs 0.35 kg, enabling installation in densely arranged control panels. A front-mounted seven-segment LED displays operating codes for status monitoring and diagnostics. The housing withstands impacts up to 20 m/s², helping the unit tolerate vibration near operating machinery.
Electrical isolation is supported by a dielectric withstand rating of 1100 VAC for one minute between power and ground. The unit also provides an insulation resistance of at least 5 MΩ at 500 VDC, limiting leakage between isolated circuits. Humidity tolerance reaches 90% RH under noncondensing conditions, allowing installation near washdown processes when the surrounding enclosure provides adequate sealing. Data exchange is handled through a combined RS-485, parallel I/O, and pulse-train interface. In RS-485 mode, the network uses start-stop framing and half-duplex arbitration to reduce conductor requirements while maintaining noise immunity. The unit has Class III protection, making it suitable for circuits supplied by extra-low-voltage power sources.
