CHAPTER 9 – CDP CONTROL PANEL 131
9.8 Local and remote control
The local / remote feature of the CDP control panel allows selecting
the control location of the drive.
Possible are:
•Local control
•Remote control
In this context, remote control is
not necessarily equivalent to
higher-level control. For details,
see
9.8.2 Remote control.
9.8.1 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.
9.8.2 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)
To enter remote control, press the LOC-REM key.
• Full remote control from a higher-level control
system is indicated by a blank space.
• Partial remote control (some commands
enabled locally) is indicated by the letter R.
9.8.3 Disabling / enabling local lock function
Accidental switching from remote control to local
control can be prevented with the local lock func-
tion.
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 PC with DriveWindow
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
letter 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.
