34 Operation principle and hardware description
The ACS-AP-I control panel
With the control panel, you can:
•
start and stop the supply 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.
The Run enable command at digital input DI2 must be on (1) so that the DSU can be
started and stopped with the control panel. That is the case when the operating switch
[S21] is switched to the on (1) position.
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
ACS-AP-x Assistant control panels
user's manual
(3AUA0000085685 [English]). For the parameter settings, see
ACS880
diode supply control program firmware manual
(3AUA0000103295 [English]).
PC connection
There is a USB connector on the front of the control 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. See also section
Connecting a PC to the supply unit
on page
.
Fieldbus control
You can control the supply unit through a fieldbus interface if the unit is equipped with an
optional fieldbus adapter, and when you have configured the control program for fieldbus
control with the parameters. For information on the parameters, see
ACS880 diode supply
control program firmware manual
(3AUA0000103295 [English]).
Note
: To be able to switch the main contactor or breaker [Q2] and the supply unit on and
off (Run enable signal) through fieldbus, the Run enable command at digital input DI2
must be on (1). Typically, that is the case when the operating switch [S21] is switched to
the on (1) position.
