Bus voltage level at which regeneration
avoidance operates. When the bus voltage
level is set to low, overvoltage error will be
less apt to occur. However, the actual
deceleration time increases.

Frequency limit invalid
Responsiveness at activation of
regeneration avoidance.
A larger setting of Pr. 886 will improve
responsiveness to the bus voltage change.
However, the output frequency could
become unstable.
When vibration is not suppressed by
decreasing the Pr. 886 setting, set a
smaller value in Pr. 665.
