Description
Control of the supply unit of the drive, such as DC voltage and
reactive power reference.
Note that the references defined here must also be selected
as the reference source in the supply control program to be
effective.
This group is only visible when supply unit control has been
activated by parameter
See also section Control of a supply unit (LSU)
Enables/disables the internal INU-LSU state machine.
When the state machine is enabled, the inverter unit (INU)
controls the supply unit (LSU) and prevents the inverter unit
from starting until the supply unit is ready.
When the state machine is disabled, the status of the supply
unit (LSU) is ignored by the inverter unit.
INU-LSU state machine disabled.
INU-LSU state machine enabled.
Enables/disables control panel and PC tool access to the
supply unit (line-side converter) via the inverter unit (motor-
side converter).
Note: This feature is only supported by the following drives:
• ACS880-11
• ACS880-31
• ACS880-17 based on an integrated drive module
• ACS880-37 based on an integrated drive module.
Control panel and PC tool access to supply unit via inverter
unit disabled.
Control panel and PC tool access to supply unit via inverter
unit enabled.
Defines the maximum time the supply unit (LSU) is allowed
for charging before a fault
generated.
Maximum charging time.
Defines a stop delay for the supply unit. This parameter can
be used to delay the opening of the main breaker/contactor
when a restart is expected.
Supply unit stop delay.
(Only visible when IGBT supply unit control activated by
95.20)
Displays the DC voltage reference sent to the supply unit.
This parameter is read-only.
DC voltage reference sent to supply unit.
(Only visible when IGBT supply unit control activated by
95.20)
Selects the source of the DC voltage reference to be sent to
the supply unit.
None.
