Network Configuration Parameters
Because the ASD-NANOCOM interface supports several different protocols,
some amount of configuration must be performed prior to inclusion on the
chosen network. This configuration is performed by setting certain drive
parameters, some of which dictate the characteristics of the network
communication, and some of which serve to facilitate the transfer of data
between the drive’s control board and the interface itself.
Throughout this section, take special note that the values of parameters
in the
Program…Comm Settings
group are only validated upon drive
power-up initialization.
Therefore, if any of these parameters are changed,
be sure to cycle the drive’s incoming power to validate the changes.
7.1
Primary Parameter Settings
The primary parameters are used by the ASD-NANOCOM interface to
configure itself on the RS-485 network. These parameters are located in the
Program…Comm Settings
group, and are as follows:
ASD Number
Ext Comm Cfg #1
Ext Comm Cfg #2
Ext Comm Cfg #3
Ext Comm Cfg #4
Ext Comm Cfg #5
Ext Comm Cfg #6
Ext Comm Cfg #7
Ext Comm Cfg #8
These parameters are used as follows:
ASD Number
: Sets the drive’s station number on the network. Although this
parameter is adjustable from 0-255, not every value is a valid entry. Refer to
the protocol-specific sections of this manual (sections 8 through 10) for details
pertaining to the allowable station number assignment range for each
supported protocol.
Ext Comm Cfg #1
: Selects the RS-485 protocol. Allowable values are:
Modbus RTU............
0
Metasys N2..............
1
Siemens FLN...........
2
All other values will result in an INVALID PROTOCOL error indication (refer to
Ext Comm Cfg #4
).
