Fault Masks
A number of the faults within the drive may be selectively enabled or disabled by you. To view or
modify the current fault mask settings, press the [F4] key on the SETUP screen.
A typical screen as shown in Figure 42 shows all of the user maskable faults. Associated with
each fault is the state of the mask. If OFF, it means the fault is disabled and will not occur. The
normal state is ON or enabled.
To change the state of the mask, use the [cursor up] or [cursor down] keys to select the desired
fault and press the [enter] key. Each press of the [enter] key will toggle the state of the mask as
shown in Figure 43. (If nothing happens, you do not have proper access to the drive. Exit to the
SETUP screen and refer to the section entitled "Enter/Modify a Password (Access)" to gain
access).
This screen shows all fault masks regardless of their current state. The fault masks can be
viewed according to their state by pressing the [F7] key on the FAULTS SETUP screen. This will
display the FAULTS OVERVIEW screen, typical of Figures 44 & 45.
