Product Description:
The PB1D002R100 servo driver belongs to the PB SANMOTION Servo Drivers series from Sanyo Denki. It conditions incremental sensor feedback and delivers current-mode regulation for compact DC brushless motors used in pick-and-place gantries, laboratory instruments, and mobile robots. By combining power switching, communication, and sensor conditioning in one board-level package, the driver simplifies axis integration and maintains velocity or position loops executed in the supervisory PLC. Its modest thermal footprint also suits battery-based or space-limited equipment.
Command and diagnostic traffic moves over half-duplex RS-485 links, allowing multidrop wiring for up to 32 nodes. A microcontroller issues PWM control signals to the output stage so torque follows reference commands. The power section accepts a bus voltage of 24/36 VDC ±10%, matching common industrial logic supplies. Under continuous load, the unit draws up to 2.7 A RMS, and winding excitation peaks at 2 A to match PB-series motors. Speed regulation spans 0 to 4500 rpm, while selectable electronic gearing provides feedback resolutions of 200/800/1600/3200/6400/12800 pulses per revolution, allowing resolution to be balanced with bus bandwidth. Five optically isolated inputs capture limit or home signals, and four transistor outputs send alarm or in-position states to the controller.
The aluminum case measures 100 × 42.5 × 80 mm, permitting direct installation on DIN rail carriers beside sensor blocks. Rated operation is maintained from 0 to 55 °C, and storage down to -20 °C supports inactive equipment without temperature conditioning. Communication rates of 9600/38400/115200/128000 bps are selected through DIP switches to balance network loading with update frequency. A single-supply topology reduces wiring requirements. The unit withstands vibration levels of 0.5 G, making it suitable for mobile chassis applications, while its general-purpose inputs and outputs remain functional throughout the operating temperature range.
