When the calibration completes, the program computes the linear fit for both the
positive and negative motion. The line for parameters are displayed at the top left
and top right of the plot in the form Y = Intercept + Slope * X. The two slopes
(87.0 and 86.9 in the example below) should be within 0.3 of each other.
The program displays the positive and negative limits as horizontal dashed lines.
Note: The PosLimitOffset and NegLimitOffset entries in the [TxMotor] section
of the SQDRIVER.INI file determine the motion limits relative to the
mechanical stops. If these entries are not present, or are zero, the motion
limits are set to the mechanical limits.
The program then changes the plot title to PRESS ANY KEY TO CONTINUE.
8. Press the <Enter> key and the program prompts:
The motor_direction, calibrate_position, pos_limit_position and
neg_limit_position
fields have the same interpretation as discussed under
MOTOR$AY.
9. Type Y<Enter> to accept the calibration values or N<Enter> to reject them.
motor_direction=1
calibrate_position=1,2287,27446,43,12563,1026,1026,3096
pos_limit_position=604777
neg_limit_position=0
