6. Press the
<Enter>
key and the program prompts.
Note: The last calibration scan data is saved in the file MOTOR_TY.DAT. You
can reanalyze the data–e.g., after editing SQDRIVER.INI–by typing the
command CALIBRATE @MOTOR_TY.DAT
at the MOTOR$TY>
prompt in SQDRIVER.

1. Select the TX motor device driver by typing:
MOTOR$TX<Enter>
2. At the MOTOR$TX> prompt in SQDRIVER, type:
CALIBRATE<Enter>
The program prompts:
The program moves the TY (W only) and AY motors to their center positions
and prompts:
This message displays on all systems. On only A and SL systems, you must use a
digital level to set the C-arm to 0º +0º. On other systems, ignore the message.
3. Press
<Enter>
and the program prompts:
4. The program moves the table to the front. When TX hits the outer mechanical
stop for the first time press <Esc>.
5. Check the position value. It must be 1000±5. Adjust if necessary.
If out of range, loosen the coupling setscrew and manually rotate the encoder
until the readback is 1000±5 (i.e., in the range 995-1005) and then tighten the
coupling setscrew.
6. Repeat the calibration procedure above but now, when TX hits the outer mechan-
ical stop, press
<Enter>
.

Press <ESC> to stop calibration.
Use the Table IN / OUT switch to move the C-Arm to 0 degrees.
Press <Enter> when the C-Arm is positioned.
Press <ESC> to stop calibration.
