Type
Y<Enter>
to accept the calibration values or
N<Enter>
to reject them.
Note:
The last calibration scan data is saved in the file
MOTOR_TX.DAT
. You can reanalyze
the data–e.g., after editing
hardware.ini
–by typing the command
CALIBRATE
@MOTOR_TX.DAT
at the MOTOR$TX> prompt in SQDRIVER.EXE.
MOTOR$AR (QDR 4500A and SL)
Before beginning this procedure, make sure that the AR motor encoder
is not
clamped to the
drive shaft tubing.
1.
Select the AR motor device driver by typing
MOTOR$AR<Enter>
2.
Then, at the MOTOR$AR> prompt in SQDRIVER.EXE, type
CALIBRATE<Enter>
The program prompts:
Press <ESC> to stop calibration.
The program moves the TY and AY motors to their center positions, then moves the TZ
motor to its topmost position and prompts:
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.
3.
Remove the bottom C-arm cover.
4.
Place the digital level on the bottom of the C-arm tank assembly (
not on the top of the
C-arm
) and use the Table IN/OUT switch on the operator panel to move the C-arm until
it is level ±0.1º.
5.
Remove the level
6.
Press
<Enter>
.
The program prompts
Press <ESC> to stop calibration.
The program moves the TZ table to its top most position and moves the TX table inwards
until it almost touches the C-arm. It rotates the C-arm by 2 degrees to obtain an initial
estimate of the encoder calibration and then prompts
Press <Enter> when the AR motor reaches the AP mechanical limit.
Press <ESC> to stop calibration.
