￭ ACX-AP-x control panel
The ACX-AP-x control panel is the user interface of the unit. With the control panel, you
can:
• start and stop the unit
• view and reset the fault and warning messages, and view the fault history
• view actual signals
• change parameter settings
• change between local and external control.
To be able to start and stop the unit by the control panel, you must have the
parameter-defined Run enable signal and Start enable signal on (1). The control panel must
also be in local control mode.
To change between local and remote control mode, press the Loc/Rem key of the control
panel. For the instructions on the use of the panel, see

manual.
￭ PC connection
There is an USB connector on the front of the panel that can be used to connect a PC to
the converter. When a PC is connected to the control panel, the control panel keypad is
disabled.

You can control the converter unit through a fieldbus interface if the unit is equipped with
an optional fieldbus adapter, and when you have configured the control program for the
fieldbus control with parameters. For more information on parameters, see
