4 Startup procedures
4.1 Setting Up SED2 parameters
See SED2 Getting Started Guide, document no. CM1G5192en for procedures to
commission and start up the VSD.
The following table lists the SED2 parameter settings that are required for correct
communications and control of the VSD with a LON module.
CAUTION:
Changes made to the parameters other than what is listed in the table below can re-
sult in damaging the VSD or building equipment.
4.1.1 Required SED2 parameter settings for the operation
of the LON module
Parameter number/name Value
P0003: User access level
Set to 3 to allow access to required parameters (re-
set back to the original value after adjustments are
done)
P2040: CB telegram off time
Set to 0 (watchdog disabled) to tell the VSD to start
looking for communications
P2041 (index 0): CB parameter
Set to 1 for FLN (L
ONWorks) network control
P0700 (index 0): Verify settings.
This is usually done during the
Quick Commissioning procedure
Set to 6 tells the VSD to look for a start command via
LON in the auto mode
P1000 (index 0): Verify settings.
This is usually done during the
Quick Commissioning procedure
Set to 6 tells the VSD to look for its speed source via
LON in the auto mode
To commission the SED2 LON module, it is mandatory to use the SED-LON.XIF and
SED2-LON.NXE files contained on the supplied CD-ROM. All files required for com-
missioning are on the CD-ROM. Program ID 80:00:81:3C:0A:04:04:03.
Files of earlier versions with Program ID 80:00:81:3C:0A:04:04:00 cannot be used.
NCI (network configuration characteristics)
When configuring the LON node point during commissioning of the LON module, the
settings of the VSD are read out.
Changing the Network Configuration Characteristics
To change the communication parameters, the VSD must have stopped. Otherwise, the
parameters can only be written, but cannot be transferred to the VSD.
Network Configuration Characteristics NCI – SCPT
The configuration characteristics exist as network variables (nci) and configuration
properties (SCPT). When making the settings, always use the nci network variables
since some LNS tools do not correctly implement the display of the configuration prop-
erties (SCPT).
