Product Description:
The 105-032002-01 personality module is produced by Pacific Scientific for the 105 Motion Control Cards series. As a plug-in daughterboard, it provides signal conditioning between the host controller and connected drives in industrial automation cells. The module tailors command scaling, feedback handling, and direction logic so that SC-series motion controllers can issue precise step or velocity references to stepper or servo amplifiers on multi-axis machinery. This arrangement allows the same controller platform to support different amplifier interfaces without changing the base card.
Analog command fidelity starts with a 16-bit A/D converter that pairs with the ±12.5 V input span. Within this range, the module maintains 0.25% command linearity, minimizing scaling error between the controller’s numeric value and the drive output. The input is presented to a front-end buffer whose impedance is 100 kΩ, reducing loading on external potentiometers or signal generators. Serial diagnostics are available through a 9600 baud asynchronous link, allowing parameter checks without removing the card from the rack. Stable analog scaling is important when the controller must translate commanded speed or torque into repeatable drive behavior across multiple axes. For deterministic step generation, the board requires a direction setup time of 380 ns and a matching hold time of 380 ns, while negative and positive step pulse widths must exceed 1.0 µs and 1.25 µs, respectively. It is electrically keyed to operate only with SC320 or SC720 controllers.
High-speed feedback and command throughput set the real-time limits of the module. Encoder signals are accepted at rates up to 750 kHz, enabling accurate position capture when axes move at elevated speeds. The step generator can stream commands to the drive at 400 kHz, a ceiling that matches modern micro-stepping amplifiers. Inside the control loop, the position sample period is 1.36 ms, while velocity is refreshed every 340 µs. Short update intervals help the controller respond to changing load conditions during interpolation and positioning tasks.
