9.3.2
Memory Operations on Drive Parameters
The drive firmware operates by using parameters stored in RAM. However, these parameters
can also be saved in non-volatile memory (E2PROM), where they are loaded into RAM upon
power up. The non-volatile memory can also be cleared. Parameters may be reset to their
default values and a set of saved parameters may be loaded from the non-volatile memory into
the RAM.
The operations described above are executed using SynqNet Direct Commands, which are
listed in the table below. The command string is used to identify the specific command. It also
indicates the syntax of the command used when communicating with the drive over the serial
port.
9.3.3
Accessing Individual Parameters
Use the sqDriveParam Utility for accessing individual parameters. The syntax follows the
conventions listed below.
•
x
is the node number. Nodes are numbered starting from zero.
•
y
is the drive, or axis, number on that node. Drives are numbered starting from zero.
•
<parameter index>
identifies the parameter being accessed.
•
<data value>
is the data being written to the parameter.
Syntax for reading drive parameters:
sqdriveparam -server <ip address> -node x -drive y -read <parameter index>
Syntax for writing drive parameters:
sqdriveparam -server <ip address> -node x -drive y -write <parameter index> -data <value>
Examples
To read the value of the drive rated peak current:
sqdriveparam -server <ip address> -node x -drive y -read 0x3
Set the encoder resolution to 2048:
sqdriveparam -server <ip address> -node x -drive y -write 0x7 -data 2048
9.3.4
Accessing an Entire Parameter Set
Use the sqDriveConfig Utility for reading or writing an entire set of drive parameters. The utility
uses a Drive Parameter Map File that contains definitions and properties of the drive
parameters. The map file needs to match the drive processor firmware version in terms of
version number and in terms of the set of supported parameters.
Syntax for reading an entire set of parameters to a file:
SqDriveConfig -server <ip address> –node x –drive y –get <destination file name> -map <map
file name>
Syntax for writing an entire set of parameters from a file:
SqDriveConfig -server <ip address> –node x –drive y –set <source file name> -map <map file
name>
Map files for each drive are delivered with the MPI installation and can be found in the XMP\bin
subdirectory. In addition, the map file matched to a specific version of drive firmware can be
downloaded from the Drive Firmware section. Simply select the drive and retrieve the
appropriate firmware and map file information.
