ATTENTION: The

calculation of the burden resistor value. Do not change this parameter
from its factory default value unless you are replacing the Regulator
board. Failure to observe this precaution could result in damage to, or
destruction of, the equipment.

ATTENTION: When activated, inverting fault avoidance takes control of
the current minor loop by either forcing the current reference to zero (if
the drive is regenerating) or by disabling the regenerative bridge (if the
drive is not regenerating). It is the user’s responsibility to analyze the
application to determine whether or not inverting avoidance should be
used. Failure to observe this precaution could result in bodily injury.
