New Servo Control Dialog Box
This dialog box has two check box controls:
1. Disable Servo Control if Loop is Unstable. If this check box is enabled, WITE32 turns off the servo control
in case the signal from the head becomes unstable. The warning message “Servo control is turned off. Check
that the signal from the head is stable” is displayed once, and the servo control is turned off. If this check
box is disabled, WITE32 will keep the servo control enabled regardless of the quality of the signal from the
head. This may result in the recurring error messages during head positioning, however, the system will try
to control the head position using servo whenever it is possible. It is recommended to enable this option in
the production environment, such that testing the heads producing poor signal can be finished in non-servo
mode. This control is available only for Guzik V2002 spinstands. For all other spinstands this check box is
disabled.
