Product Description:
The 105-090001-01 motion control card is produced by Pacific Scientific as part of the 105 Motion Control Cards series. Designed for integration inside multi-axis automation racks, it translates high-level position, velocity, and current commands into real-time drive signals for servo amplifiers and feedback devices. By combining analog command inputs with digital resolver and encoder processing, the board coordinates closed-loop motor operation in packaging lines, robotics, and semiconductor handling. It is suited to rack-based systems that need one module to close the motor loop while exchanging signals with separate amplifiers and sensors.
At the command interface, analog input linearity is 0.1 % full scale, so voltage-to-digital conversion introduces minimal gain error across the operating range. The unadjusted offset is 50 mV and its drift is 250 µV/°C, so normal temperature changes do not require frequent recalibration. The current loop runs with a maximum bandwidth of 1.5 kHz and a discrete update time of 62.5 microseconds, which supports fast torque response in servomotors. For incremental feedback, the encoder output can toggle up to 833 kHz, while the position input path accepts step-and-direction streams to 800 kHz. Commanded position data is held with 0.33 arc min resolution, and the card can be cabled up to 50 m from motor-mounted sensors without signal conditioners. The step-and-direction interface allows the card to accept pulse-train commands from external motion sources without a separate translator board.
Higher-level motion functions use deterministic refresh cycles, with the position loop updating every 1 msec and the velocity loop every 250 µsec. The system reaches full operational readiness 2.0 sec after power-up, which reduces delay before axis control becomes available. Resolver excitation is 6510.42 Hz, and absolute electrical accuracy is ±5.3 arc min. Mechanical position is digitized at 24 bits/rev, and velocity granularity is 0.0143 rpm for fine low-speed feedback. This level of resolver processing supports both long travel moves and small position corrections during slow operation.
