ENERAL
The SuperDrive performs extensive checks and monitoring to protect the motor, drive and vehicle
from damage and prevent operation under unsafe conditions. Two response levels are
employed: warning level and error level. Errors are serious problems that prohibit continued
operation of the AC SuperDrive. Less serious problems that permit continued AC SuperDrive
operation, often at reduced capacity, produce warnings.
For some items monitored, the AC SuperDrive provides a two stage response including a
warning when the item is approaching it’s safe operating limit and an error response when the
safe operating limit is exceeded.

RRORS
When an error is detected, the AC SuperDrive operating software immediately stops motion then
shuts down the drive’s power output to the motor. Concurrently, the AC SuperDrive’s internal
error status is updated to reflect the error code(s) for existing error conditions and an emergency
message containing the new error status is sent. The AC SuperDrive’s status indicator changes
from steady on to flashing.
