Product Description:

The 105-093001-01 motion control card is produced by Pacific Scientific and belongs to the 105 Motion Control Cards series. It installs in a host controller backplane and issues incremental position, velocity, and trajectory commands to downstream drives, enabling coordinated multi-axis movement in industrial automation cells. By housing its own command interpreter and serial interface, the board offloads real-time motion tasks from the main PLC so packaging lines, material handlers, and electronic assembly tools can execute deterministic moves while the supervisory computer concentrates on higher-level sequencing.

Axis selection is managed over an address range of 0 to 255, chosen with an 8-position DIP switch. The factory default is address 255 for quick single-node setup. Communications use RS-232/RS-485 at a fixed rate of 9600 baud, allowing either point-to-point links or multidrop cabling. A 9-contact female D-sub connector on the board edge carries the specified TX and RX pairs for both standards, so the host can wire directly without adapter boards. The same connector supplies separate pins for differential RS-485 lines, reducing noise coupling when several axes are chained along a machine frame.

The card provides an auxiliary logic rail of +5 VDC that can source a maximum of 200 mA for limit switches, LEDs, or encoder reference marks, removing the need for an external supply. All operating parameters and user motion tables are saved in onboard EEPROM, and personality or communication data can be mirrored in OC930 and SC900 areas for secure field updates. Network capacity scales to 32 axes, and the all-digital setup method eliminates trim potentiometers, so setup requires only software commands and the DIP switch. These features let a single card supervise a compatible SC900 drive and resume operation immediately after power cycling without manual intervention.
