    315D and 100 mN for the 322D. The 315D is the fastest version of our length controllers. The 315D has a step response time of 250 microseconds and the 322D has a response time of 350 microseconds. To achieve the fastest possible step response times the control electronics uses a proportional/integral/derivative (PID) servo control loop.

    4. Attach the lever arm to the motor shaft (for the 315D the arm is attached at the factory). Gently, push and the lever arm back forth. It should move freely until the mechanical stops are reached.

    3.2 Controlling Force High-speed length controllers cannot control force by themselves. Aurora Scientific has a digital controller available that interfaces with a high-speed length controller and a force transducer and allows the user to control force. Our model 600A Digital Controller can generate critically damped force clamps in as little as 1.5 msec.

    High Speed Length Controllers Instruction Manual Model: 315D | 322D 3.4 Inhibit Shutdown All models include an inhibit circuit that interrupts the current drive to the motor and lights the FAULT LED. When the instrument is inhibited all external control inputs (Length In and Length Offset) are disconnected internally and power is cut to the motor.

    Length Scale Factor = actual movement measured / LENGTH OUT voltage Example: For a model 315D system the actual movement is measured as 1.5 mm and LENGTH OUT is measured as 9.92 volts. Therefore, the Length Scale Factor will be 1.50 mm/9.92 volts = 0.151 mm/volt.

    The researcher wants the system step response slightly faster or slower. Please read the entire procedure before attempting any changes. It is possible to damage the motor if the procedure is not understood completely. If there are any questions, please contact Aurora Scientific Inc.

    Place the arm on the motor such that it swings about the same distance to either side of the motor centerline. Tighten the arm's clamp. For model 315D the arm is factory installed. *** CAUTION: Lethal voltages are exposed during this procedure. *** Use caution whenever the top cover of the electronics box is removed.

The four potentiometers R28, R25, R59, and R31 should now be alternately turned in a generally CW direction until a critically damped square wave with a step response time as shown in the table below is achieved.
