Set the bus voltage level at which
regeneration avoidance operates. When the
bus voltage level is set to low, overvoltage
DC380V
0.1V 300 to 800V error will be less apt to occur. However, the

9999 Frequency limit invalid
Adjust responsiveness at activation of
regeneration avoidance.
0.1% 100% 0 to 200% A larger setting will improve responsiveness
to the bus voltage change. However, the
output frequency could become unstable.
