Product Description:

The 105-050001-01 motion control card is produced by Pacific Scientific and belongs to the 105 Motion Control Cards series. Designed for industrial automation, the board executes position, speed, and torque commands to coordinate servo or stepper axes from a host controller or HMI. By combining serial communication with onboard feedback processing, it acts as an intermediary that simplifies integration of precision motor stages into packaging lines, material-handling equipment, and other automated machinery.

Its analog command port presents a high input impedance of 50 kΩ, so signal sources are not heavily loaded during motion sequences. Communications travel over an RS-232 or RS-485 link and can reach a maximum rate of 9,600 baud; each serial data word is 10 bits, providing start, stop, and parity framing. Closed-loop velocity is supported up to 10,000 rpm, while the controller resolves each revolution into 4,096 steps per revolution for smooth interpolation. Both the discrete input set and output bank are scanned at an interval of 1.024 ms, matching the input sampling and position-loop update periods to maintain synchronous responses with external sensors.

This update framework yields a speed resolution of 0.01 rpm and a positioning accuracy of 15 arcmin, which let the card fine-tune axis motion without dithering. The integrated fault output, rated at 30 VDC with a 25 mA sink capacity, can drive an interlock relay whenever overcurrent, following error, or serial watchdog events are detected. Non-volatile parameter storage endures up to 10,000 cycles of write activity, so frequent recipe changes do not threaten data retention. Additional monitoring resources include a 4.4 VDC full-scale current sense channel and a tachometer monitor that scales 0.56 V per krpm, both captured every 1.024 ms to support real-time diagnostics without external meters.
