QA Table
1. Before attempting to start adjusting the D/A reference voltage, ensure that the DC power source output voltage has been
properly adjusted.
5.0V ± 0.01V
LDAREF
CDAREF
2. Using a digital voltmeter, measure the voltage at the check pins [TP6 (LDAREF), TP5 (CDAREF), TP4 (RDAREF)]. Use
TP3 (AGND) for the ground pin. (E8601725OAO is only on TP5.)
RDAREF
3. Turn variable resistors [VR3 (LREF), VR2 (CREF), VR1 (RREF) as necessary to make the measurements taken fall within
the specifications.
Here is a list of correspondence between the check pins and variable resistors.
TP6 LDAREF VR3 LREF
TP5 CDAREF VR2 CREF
TP4 RDAREF VR1 RREF
Directly concerned with the operation of Z-axis and $-axis motors of the head, it greatly affects placement accuracy.
1. Degraded placement accuracy
2. Laser error
3. ATC nozzle change error
4. Oscillation at stopping
5. Servo driver alarm
