ABB ACS880-107

The control panel can be mounted on a platform on the inverter cubicle door. The
maximum number of platforms on one door is four, but one control panel can be used
to control several units through a panel link.
For details on the control panel, see ACS-AP-I, -S, -W and ACH-AP-H, -W Assistant
control panels user's manual (3AUA0000085685 [English]).
￭
Control by PC tools
There is a USB connector on the front of the panel that can be used to connect a PC
to the drive.
￭
Fieldbus control
The inverter unit can be controlled through a fieldbus interface if the unit is equipped
with an optional fieldbus adapter, and when the control program has been configured
for fieldbus control by parameters. For information on the parameters, see the
appropriate firmware manual of the inverter unit.

Other control devices
DC switch-disconnector (option +F286)
The inverter unit can optionally be equipped with a DC switch-disconnector [Q2] which
allows the isolation of the unit from the DC link. Before the unit is reconnected to the
DC link, the capacitors of the inverter module(s) must be charged through a charging
circuit.
With frame R1i…R5i inverter units, the DC switch-disconnector controls all of the
inverter modules within that particular cubicle. Each module is additionally fitted with
DC fuse disconnectors or a switch-disconnector. If R1i…R5i units are ordered in their
own compartments (option +C204), the cubicle is equipped with a common DC
switch-disconnector and the modules with dedicated DC switch-disconnectors as
standard.
The status of the DC switch-disconnector (as well as module-specific disconnectors
of R1i…R5i modules) is connected to the inverter(s). By default, the inverter is disabled
when the DC switch-disconnector (or a DC fuse disconnector) is open.
WARNING!
Do not operate the DC switch-disconnectors under load.
WARNING!
Do not operate the DC fuse disconnectors under load or under voltage.
WARNING!
With frame n×R8i inverter units, both the DC switch-disconnector [Q2] and the
charging switch [Q10] must be opened to disconnect the inverter unit from
the DC link.
Charging switch (frame R8i and multiples only)
Frame n×R8i inverter units equipped with a DC switch-disconnector (option +F286)
have a charging circuit including an BSFC-02 charging control unit and a charging
switch [Q10] on the cubicle door. Before closing the DC switch-disconnector, the user
