Product Description:
The PB2D003R1UM servo driver is produced by Sanyo Denki as part of the PB SANMOTION Servo Drivers series. It is mounted inside machine cabinets to energize and regulate multiple motors. The driver translates upper-level motion commands into phase-accurate current so that conveyors, actuators, and indexing mechanisms reach target positions and speeds in automated production lines. Its multi-axis design allows several coordinated movements to be managed by one module.
The driver supports a selectable command resolution of 200/800/1600/3200/6400/12800 P/R, allowing the pulse density to be matched to the required positional granularity. Communication with the host controller uses half- or full-duplex RS-485 at 9600/38400/115200/128000 bps, and the faster settings shorten scan times during synchronized movements. The control electronics operate from a 24 VDC (±10%) supply that isolates the low-power logic from the motor bus. Each winding can receive up to 3 A per phase, providing the magnetizing force used for torque production. The main bus accepts 24 or 36 VDC and permits rotor speeds up to 4500 rpm, covering typical light-duty stages and feeders. The driver can operate at temperatures ranging from 0 °C to 55 °C. Communication uses the 8-E-1 data format, and the interface combines RS-485 with parallel I/O so time-critical signals can bypass serial latency. Input commands are recognized between 5 and 24 VDC, while driver outputs are rated for 30 VDC at 30 mA. Relative humidity may reach 90% without condensation.
The unit coordinates up to 4 control axes, allowing one module to operate a small gantry or multi-station indexer. The RS-485 trunk has a maximum length of 100 m, supporting distributed mounting across larger machines. An address range of 1 to 15 slave stations allows several drivers to share a single communication line. Fail-safe biasing monitors cable integrity, while parallel fault signals provide an immediate stop function. The data link accommodates half- or full-duplex wiring. Discrete connectors carry the required main and control voltages without the need for separate breakers.
