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
1.
See also section Control of a supply unit
(LSU) (page 76).
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 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,
failedis 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.
Note: This parameter is read-only.
DC voltage reference sent to supply unit.
