    Cambridge Technology Model 6210H Instruction Manual 1.0 Introduction and Warnings This manual was written to help the customer use the Model 6210H scanner successfully. There are several warnings and precautions written throughout this manual. Read this manual carefully. It is possible to damage the scanner by exposing it to rough handling or contaminants.

Setup for settling time: Using CTI’s recommended servo, CTI’s 3mm Y-mirror, moving a 0.1° step, and settled to within 99% of the final position. 3. Using the Cambridge Technology, Inc. Position Demodulator circuit.

    CTI driver electronics. The 6210H is now available in a variety of connector versions so that the smallest scanner in the world is now one of the most flexible to integrate. The standard 6210H comes with the standard or “straight”...

  • Page 7: Mounting Scheme

    To calculate the necessary heatsinking for the 6210H, there are two approaches. 1. Worst case analysis: This assumes that there are two scanners bolted to a common heatsink and both are dissipating their full power.
  • Page 8 If any part of this procedure is not completely understood, contact CTI for technical assistance. For the 6210H scanner, the only valid mounting surface is the long cylindrical section of the body. See the Outline Drawing in Section 5.1 at the end of this manual. The scanner must be mounted by this surface to adequately transfer the heat out.

  • Page 9: Mirrors

    Model 6210H Instruction Manual Mirrors The 6210H is designed to have the mirror glued directly into a slot in the end of the output shaft. This minimizes the extra inertia required to hold the mirror in a removable mount. The standard slot width is shown in the outline drawing in Section 5.1.

  • Page 10: Replacement Mirror Mounting Procedure

    The Mirror Replacement Kit contains a two-part stainless steel fixture. The larger piece, referred to as the Alignment Tool, slips over the drive housing of the 6210H. The Alignment Tool has a semi- circular window for viewing the mirror installation and curing processes. The smaller piece, the Plunger, has ends that are machined for the two different mirror widths.

  • Page 12: Cabling

    Model 6210H Instruction Manual Cabling The Model 6210H and 6210HR motors have been optimized to be as small as possible but still use a connector. The 6210H employs a small, straight 8-pin Amp connector. The 6210HR uses a right angle version of this connector. The standard cables for both are:...

  • Page 13: Attaching The Cable To The Motor

    This procedure should be used when the cable end to be attached to the motor has been properly prepared. The cable is properly prepared when it leaves Cambridge Technology, but if the cable length needs to be modified, or if a wire is damaged during assembly, refer to Section 3.4.2, Modifying the Cable Length, shown below.

Cut off any excess wire that protrudes from the far side of the soldered hole to minimize the possibility of shorting. **Caution: Do not attempt to clean the flux off of the solder connections. The cleaner may enter the scanner and contaminate it.

    Cambridge Technology Model 6210H Instruction Manual The 6210HM For situations that require reduced angles, a different bumper design is employed which limits the rotation angle of the front stop pin of the scanner. These –M version scanners use a two-digit suffix which denotes the intended use angle in peak-to-peak optical degrees.
