Motion Controller Software 7MOT0096-N14 and Later

CAUTION
The ranges within which the ultimate switches must go active are:
•
Horizontal:
•
Vertical:
•
Rotational:
Note. It is not possible to approach the rotational ultimate limit by rotating the detector to the Z
< – 90° limit. However, testing the ultimate limit at Z
of the functionality, since the same limit switch serves both rotational limits.
Preparing for Testing Ultimate Limit Switches
Testing ultimate limit switches requires the following preparations:
•
Removing both table console covers (front and rear – if these have not already been removed)
•
Disabling software limits. This is done by sending commands to the master (rotate) motion
controller via a HyperTerminal connection
•
Starting the CardioMD acquisition software.
Before testing X axis limits, furthermore:
•
Removing the patient table pallet.
Before testing Y axis limits, furthermore:
•
Removing the patient table pallet
•
Rotating the detector assembly to approximately 110°.
Disabling Software Limits
In order to verify ultimate switches, software limits must first be disabled (the diagram in Figure
4.1 on page 4-40 may give you an idea, why). In order to accomplish this, software limits are tem-
porarily set to values well beyond the ultimate limits. For this, you need to establish a Hyper-
Terminal connection to the rotation motion controller (the motion controller to the right).
For instructions on using HyperTerminal for communicating with motion controllers, see Chap-
ter 5 Diagnostics, the section Motion Controller Diagnostics. Once the HyperTerminal connection
is established:
