No.
Control of the supply unit of the drive, such as DC
voltage and reactive power reference.
LSU control94
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 95.20 HW options word
1.
See also section Control of a supply unit
(LSU) (page 76).
On / uint16Enables/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.
LSU Control94.1
When the state machine is disabled, the status of the
supply unit is ignored by the inverter unit.

Disable / uint16Enables/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.

allowed for charging before a fault, 7584 LSU charge
failedis generated.

600.0 s / uint16Defines 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.

DC voltage reference94.20
Displays the DC voltage reference sent to the supply
unit.
Note: This parameter is read-only.
