Programming; Special Attention - Danfoss VLT 2800 Manual

I Special Attention
NB!:
Please note, that terminal 46 has been
removed from the VLT 2800 DeviceNet
card, meaning that parameter 341 - 342
are not having any function.
•
002:
If operation site = Local, then control via
DeviceNet is not possible.
•
502-508:
Selection of how to gate DeviceNet control
commands with control commands on the digital
inputs of the control card.
•
515-538:
Data read out parameters that can be used to read
various actual data from the VLT, as for example
actual status on the analog and digital inputs of the
control card thus using these as inputs to the master.
• 800 Protocol Select
Select DeviceNet in this parameter.
• 801 Baud rate select
Selection of DeviceNet transmission speed.
•
833 Fieldbus enable
Enable the DeviceNet communication. The
default setting is disable.
• 904 PPO selection
Selection of Instance type.
• 918 Station address / MAC ID
Set the Station address / MAC ID in this parameter.
620 Operation Mode
(OPERATION MODE)
Value:
✭Normal operation (NORMAL OPERATION)
Control card test (CONTROL CARD TEST)
Initialize (INITIALIZE)
Function:
In addition to its normal function, this parameter
can be used to test the control card.
There is also the opportunity to perform an
initialisation at the factory setting for all parameters
in all Setups, with the exception of parameters
500 Address, 501 Baudrate, 600-605 Operating
data and 615-617 Fault log.

VLT 2800 / FCD 300 DeviceNet
Description of choice:
For FCD 300 connections see FCD 300 Design
Guide MG.04.AX.YY par. 620.
Normal function [0] is used for normal
operation of the motor.
Control card test [2] is selected if you wish to check
the control card's analog/digital input, analog/digital
outputs, relay outputs and 10 V and 24 V voltages.
The test is performed as follows:
18, 27, 33 are connected to relay terminal 03.
19, 29, V+ are connected to relay terminal 02.
50 - 53 are connected.
42 - 60 are connected.
55 - V- are connected.
12 is connected to relay terminal 01.
Use the following procedure for the control card test:
1. Select control card test.
2. Disconnect the mains voltage and wait until the
light in the display has disappeared.
3. Mount according to drawing and description.
4. Connect the mains voltage.
5. The frequency converter automatically undertakes
a test of the control card.
If the frequency converter displays a fault code from
37-45, the control card test has failed. Replace the
control card to start up the frequency converter.
If the frequency converter comes into Display mode,
[0] the test is OK. Remove the test connector and
[2] the frequency converter is ready for operation.
Parameter 620 Operating mode is automatically
[3]
set to Normal operation [0].
Initialisation [3] is selected if you wish to use
the unit's factory setting.
Procedure for initialisation:
1. Select Initialisation [3].
2. Disconnect the mains voltage and wait until the
light in the display has disappeared.
3. Connect the mains voltage.
4. An initialisation is performed in all parameters
in all Setups, with the exception of parameters
