ATTENTION: The user must provide an external,
hardwired emergency stop circuit outside of the drive
circuitry. This circuit must disable the system in case
of improper operation. Uncontrolled machine
operation may result if this procedure is not followed.
Failure to observe this precaution could result in
bodily injury.
