32 Operation principle and hardware description
Control panel
The ACS-AP-S is the user interface of the drive. It provides the essential controls such as
Start/Stop/Direction/Reset/Reference, and the parameter settings for the control program.
One control panel can be used to control several drives through a panel link.
The control panel can be removed by pulling it forward from the top edge and
disconnecting the panel cable. The panel is reinstalled in reverse order. For the use of the
control panel, see the firmware manual or ACS-AP-X assistant control panel 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. When a PC is connected to the control panel, the control panel keypad is disabled.
Common mode filter
The drive is equipped with a common mode filter as standard. The filter contains ferrite
rings mounted around the drive AC busbars. The filter protects the motor bearings by
reducing the bearing currents.
More information on when the option is required: See section Examining the compatibility
of the motor and drive on page 50.
Descriptions of cabinet options
Note: All options are not available for all drive types, do not coexist with certain other
options, or may require additional engineering. Check actual availability with ABB.
