DC bus
voltage level
DC760V
300~800V
Set the 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.
The set value must be higher than
the power supply voltage×
