POINT
When absolute position data is received at power ON, for example, if a
negative coordinate position which cannot be handled by the A1SD71 is
detected, the ABS coordinate error (Y4B ON) is generated. If this error is
generated, move the axis into the positive coordinate zone in JOG operation.
Then, turn OFF the servo-on pushbutton switch and turn it ON again.
