Danfoss VLT CDS 303 User Manual

[Hand On] enables control of the frequency converter via
the LCP. [Hand on] also starts the motor compressor, and it
is now possible to enter the motor compressor speed data
by means of the arrow keys. The key can be selected as [1]
Enable or [0] Disable via parameter 0-40 [Hand on] Key on
LCP.
External stop signals activated by means of control signals
or a serial bus will override a “start“ command via the LCP.
The following control signals will still be active when
[Hand on] is activated:
•
[Hand On] - [O] - [Auto On]
•
Reset
•
Coasting stop inverse
•
Reversing
•
Set-up select lsb (least signicant bit) - Set-up
select msb (most signicant bit)
•
Stop command from serial communication
•
Quick stop
•
DC brake
[O] stops the connected motor compressor. The key can
be selected as [1] Enable or [0] Disable via
parameter 0-41 [O] Key on LCP.
If no external stop function is selected and the [O] key is
inactive the motor compressor can be stopped by discon-
necting the voltage.
[Auto On] enables the frequency converter is to be
controlled via the control terminals and/or serial communi-
cation. When a start signal is applied on the control
terminals and/or the bus, the frequency converter will
start. The key can be selected as [1] Enable or [0] Disable
via parameter 0-42 [Auto on] Key on LCP.
NOTICE!
An active HAND-OFF-AUTO signal via the digital inputs
has higher priority than the control keys [Hand on] and
[Auto on].
[Reset] is used for resetting the frequency converter after
an alarm (trip). It can be selected as [1] Enable or [0]
Disable via parameter 0-43 [Reset] Key on LCP.
The parameter shortcut can be carried out by holding
down the [Main Menu] key for 3 seconds. The parameter
shortcut allows direct access to any parameter.
5.2.4 Quick Transfer of Parameter Settings
Once the set-up of a frequency converter is complete,
store the data in the LCP or on a PC via MCT 10 Set-up
Software.
5.2.5 Data Storage in LCP
1. Go to parameter 0-50 LCP Copy in the Main Menu.
2. Press [OK].
3. Select [1] All to LCP.
4. Press [OK].
All parameter settings are now stored in the LCP indicated
by the progress bar. When 100% is reached, press [OK].
NOTICE!
Stop the motor compressor before performing this
operation. The LCP can now be connected to another
frequency converter and the parameter settings copied
to this frequency converter as well.
5.2.6 Initialization to Default Settings
Initialize the frequency converter to default settings in two
ways:
Recommended initialization (via
parameter 14-22 Operation Mode)
1. Select parameter 14-22 Operation Mode.
2. Press [OK].
3. Select [2] Initialization.

frequency converter is now reset.
parameter 14-22 Operation Mode initializes all except:
•
parameter 8-30 Protocol
•
parameter 8-31 Address
•
parameter 8-32 FC Port Baud Rate
•
parameter 8-33 Parity / Stop Bits
•
parameter 8-34 Estimated cycle time
•
