2.4.3 How to Clear the Drive Fault and Drive Warning Registers

After a drive fault has been detected, the programmer must do the following before the
drive can be restarted:

Step 1. Reset the command bit that is currently set in the Drive Control register

(100/1100).

Step 2. Correct the fault.

Step 3. Set and reset the Fault Reset bit (register 100/1100, bit 8, FLT_RST@) to

clear the Drive Fault register (200/1200). (Note that the Fault Reset bit is
edge sensitive.)

Step 4. Set the desired command bit in the Drive Control register (100/1100).

After a drive warning has been detected, the programmer can clear the entire Drive
Warning register by setting and resetting the Warning Reset bit (register 100/1100,
bit 9, WRN_RST@). (Note that the Warning Reset bit is edge sensitive.)
