Axial Drive Controller Replacement

Prerequisites

Overview

This procedure describes the steps necessary to install Axial Drive controller into the Danaher axial drive assembly. Refer to Figure 1 for a visual reference of the controller.

1 Preparation for Replacement

Procedure

    Notice Image
    • notice
    • This procedure uses many screw, lock and flat washer combinations. Make sure the order of installation has the lock washer positioned between the flat washer and head of the screw. DO NOT need remove the axial drive assembly from Gantry
  1. Remove gantry right side cover and disable axial drive, HVDC and 120VAC service switches from the service switch panel. Remove all system power at the Main Disconnect panel and use proper Lockout/Tagout procedures.

    Refer to Replacements > Gantry > Enclosure > Gantry Side Covers Removal and Re-install.

  2. Remove the gantry left side and top covers, scan window, and front cover. Connect the cover E-stop circuit to the terminators on the gantry.
  3. Remove the two cross screws from the n-shaped bracket.
  4. Disconnect all cables from existing controller and remove controller from axial drive assembly by removing the two screws attaching the bottom bracket to the axial drive with a 5mm hex wrench. Refer to Figure 2.

    Figure 2. Removing Controller Assembly

  5. Remove top L-shaped bracket from controller and axial drive assembly. Be sure to keep this bracket as it will be re-used for the installation of the new controller. Refer to Figure 3.
  6. Remove controller from bottom bracket using a 3mm hex wrench. Be sure to keep the bottom bracket as it will be re-used for the installation of the new controller. Refer to Figure 3 and Figure 4.

2 Installing controller on assembly frame

Procedure

  1. Mount new controller to bottom bracket with two M4 nuts (with lock washer) and two M4 flat washers (refer to Figure 4).

  2. Mount to bottom of drive assembly box with two M6 screws, lock washers and flat washers. Refer to Figure 2and torque according to the table below.
  3. Mount top (L-shaped) bracket onto controller with an M4 screw, lock washer and flat washer. Refer to Figure 3 for placement of bracket.
  4. Mount two plastic cable guides to the top of the second bracket with an M4 screw, lock washer and flat washer each.
    1. Refer to Figure 5 for visual reference of plastic cable guides.

3 Cable Installation and Routing

Procedure

  1. Connect axial drive power cable from terminal strip into the X4 port of the controller. Refer to Figure 7.
  2. Connect resistor assembly cable to X3 port of the controller from underneath box. Refer to Figure 7
  3. Connect motor power cable from the 2010 Axial Drive motor to the X2 port of the controller. Refer to Figure 7.

    Figure 7. Routing of axial drive power cable, brake resistor cable and motor power cable

  4. Connect feedback cable from motor to X10 port of the controller. Refer to Figure 8.
  5. Connect cable from KIM board to X1 port of the controller. Refer to Figure 8.
  6. Connect two boxed ends of KIM com. cable into X7 and X8 ports of the controller. Refer to Figure 8.
    note: The pins are positioned so that ends will only go in one way.
  7. Connect third end of this cable into X12 port of the controller. Refer to Figure 8.

4 Reassemble gantry

Procedure

  1. Turn ON the 120VAC. An "o2" code should display on the axial drive display screen. Refer to Figure 9

    Figure 9. “o2” code on axial drive display

  2. Turn OFF the 120VAC
  3. Replace the right side tilting safety cover.
  4. Replace the front, top, and left side covers and the scan window.
  5. Turn on the 120VAC, axial drive and HVDC service switches from the service switch panel.
  6. Install the gantry right side.
