9.9 Local and remote control
The local / remote feature of the CDP control panel allows selecting
the control location of the drive.
There are two possibilities:
• Local control
• Remote control
The control location is selected by pressing the
LOC-REM key on the CDP control panel.
—
In this context, remote control is
not necessarily equivalent to
higher-level control. For further
information, see
9.9.1 Local control
In local control mode, full operational control of the
drive is enabled from the local operator panel.
Commands from remote have no effect.
To enter the local control mode, press the LOC-
REM key. Local control is indicated by the letter L.
9.9.2 Remote control
In remote control mode, operational commands or
reference values usually come from a higher-level
control system via fieldbus or remote I/O.
However, with the following parameter settings it
is possible to start and stop the drive, to set the
motor's direction of rotation, and to enter refer-
ence values from the CDP control panel.
• 11.01 EXT1 START/STOP/DIR = 10 (KEYPAD) or
12.03 EXT REF1 SELECT = 1 (KEYPAD) and
12.02 EXT1/EXT2 SELECT = 1 (EXT1)
• 11.02 EXT2 START/STOP/DIR 10 (KEYPAD) or
12.06 EXT REF2 SELECT = 1 (KEYPAD) and
12.02 EXT1/EXT2 SELECT = 2 (EXT2)

9.9.3 Disabling / enabling local lock function
Accidental switching from remote control to local
control can be prevented with the lock function of
parameter 16.04.
The corresponding parameter is 16.04 LOCAL
LOCK and belongs to the parameter group 16 SYS-
TEM CTRL INPUTS.
Enabling the local lock
To enable the local lock, set parameter 16.04 to 2
(LOCKED).
With this parameter setting, local control (includ-
ing the LOC-REM key) is disabled.
If the CDP control panel or a DriveWindow PC is in
local control mode at the time that the local lock is
enabled, they remain in local control mode until
they are switched to remote control mode. This
means that the CDP control panel displays the let-
ter L until you press the LOC-REM key.
Disabling the local lock
To disable the local lock, set parameter 16.04 to 1
(OPEN). With this parameter setting, switching
between remote and local control is enabled.
