DRO 200T Troubleshooting

• If the problem remains in the same display, the readout is in error.
• If the problem follows the connection change, the linear encoder may be in
error. Refer to the Checking the Linear Encoders section of your encoder
reference manual.
Display overflow errors are indicated by dashes in all digits in an axis display.
A numeric overflow occurs when the intended measurement is too large for the
eight-digit display. Clear the error by returning the machine table into an area
where measurements can again be displayed, selecting a lower display resolution,
setting a new preset, or zeroing the display.
This error may also occur when using the automatic compensation routine while
setting the LEC parameter. An error indicates that the calculated compensation
factor was outside the acceptable range of -9999 to +9999, and usually is the
result of incorrectly entering data. Clear the error and return to the beginning of
the linear error compensation routine. Refer to page 18.
