WITE32 Release Notes Version 3.11
The following bugs were discovered in WITE32 version 3.10 or earlier, and fixed in WITE32
version 3.11. The description below explains the bug behavior as it appears in WITE32 version 3.10.
3.1 V2002 Spinstand
1. The XY Alignment test may fail with the "Servo amplifier is not calibrated - signal is too low" error message.
2. The XY Alignment and the Head Alignment tests fail in the case of low frequency heads (the heads with data rates
below 160 Mbit/s).
3. The XY Alignment test resets the loading radius to the default value in the Product Configuration dialog box.
4. The Y-limit Screw Adjustment test fails (shows unreachable destinatio n position) if non-zero Head Base
Parameters are specified in the Product Configuration dialog box.
5. The Product Parameters specified in V2002.DDT in Inches are different from parameters shown in Edit Product
Parameters dialog by 0.002%. As a result the parameters loaded into spinstand are different from parameters
specified in DDT file by 0.002%.
6. Impossible to use the Special Disk Type setting in the Product Parameters dialog box of the V2002 Spinstand
Alignment Program, because the Minimum Radius and Maximum Radius values are not stored in the product
database.
7. After performing the Y-limit Adjustment there is no software validation of Y-stage positioning and the Y-limit
screw can be hit. In the new version of WITE32, the software always checks if the destination position is
reachable before the Y-stage starts moving such that the Y-stage does not hit the screw and the warning message
is shown when the specified destination position is out of range.
8. The value of the Reset Radius in the Product Parameters dialog box is different after performing XY Alignment
with zero and non-zero head geometry parameters specified in the Product Parameters dialog box.
9. The V2002 Balancing procedure for the Custom 6 Screws and Custom 3 Screws choices from the Type dropdown
list of the Balancing Parameters frame instructs to adjust screws for counter-clockwise balancing screw
numeration instead of clockwise balancing screw numeration.
10. Cartridge, which is incorrectly installed on V2002 spinstand could hit the media or spindle. The sequence of
starting the device is modified such that the spinstand checks that the required level of vacuum is provided to the
cartridge before the X and Y motors start moving the V2002 head loader to the loading location. If the vacuum
does not reach the required level due to improperly installed cartridge, the spinstand will not move and will
provide an error message.
11. The V2002 Balancing while executed for rotation speeds higher then 10000 RPM consists of 4 stages in the case
of high imbalance:
• Screw Calibration for reduced RPM,
• Balancing for reduced RPM,
• Screw Calibration for full RPM,
• Balancing for full RPM.
In WITE32 version 3.10 the Screw Calibration for full RPM shows the wrong instruction to "Switch to Balancing
Tab to perform Balancing procedure" instead of instruction to continue with screw calibration.
