Control of the supply unit of the drive, such as DC
voltage and reactive power reference. LSU control 94
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

Control of a supply unit (LSU).
On / uint16 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. LSU Control 94.1
When the state machine is disabled, the status of the
supply unit is ignored by the inverter unit.
0 INU-LSU state machine disabled. Off
1 INU-LSU state machine enabled. On
Disable / uint16 Enables/disables control panel and PC tool access to
the supply unit (line-side converter) via the inverter unit
(motor-side converter). LSU panel
communication 94.2
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.

This setting can be used eg. when installing the drive
into an existing set-up with other ACS880 as well as
ACS800 drives.

LSU external start
command 94.5
Selects the source for LSU external start command.
This parameter is visible only if INU-ISU communication
is enabled in 92.20 bit 15.
Note: If LSU is stopped using parameter 94.5 LSU
external start command , LSU continues to run during
the time defined by 94.11 LSU stop delay .
