[Bus Reg Level]

– Firmware 4.001 & later

[Max Bus Volts]

Sets the limit that the drive DC bus voltage can rise before
a fault occurs. When this parameter is set to the minimum
value, the drive DC bus voltage is limited to 110% of
nominal voltage. [Bus Limit En] must be “Enabled” for the
drive to limit the bus voltage. This setting is used to move
the trigger point for regulation above the turn-on point for
dynamic brake or regeneration packages.
