 11-16 and 11-17 are used to set the regeneration prevention function response. A higher value increased the
response in output frequency when the DC bus voltage rises but may result instability.
 If parameter 11-16 is set to small the regeneration prevention function might not be fast enough to prevent an
over voltage condition, adjust both parameters accordingly.

 SLV control mode uses the output speed estimator for its speed feedback value. Speed control system
adjusts the output frequency to match the value of speed feedback command. The output torque command is
set by the controller output via a limiter.
