9.2.2 Monitoring Real-time Data from Drive
Some data from the drive is not part of the standard MEI I/O. However, it can be monitored in
real-time from the drive. For more information on how to monitor real-time data from the drive,
see Drive Monitor.

9.3 Accessing Drive Parameters over SynqNet
9.3.1 Introduction
The drive's functionality is designed to use various drive parameters and instructions, which are
communicated over SynqNet. Some parameters have read-only access, whereas other
parameters may have read/write access. The parameters can be stored in non-volatile memory
on the drive and are used on each power-up cycle.
Examples of read-only drive parameters are:
• drive command value (CMD_IN)
• drive model number (MODEL)
• drive bus voltage (V_BUS)
Examples of read/write drive parameters are:
• commutation offset value (COMM_OFF)
• proportional gain of the current loop (KIP)
• motor pole count (D_POLES)
Drives are shipped from the factory with motor parameters set to zero and application
parameters set to their default values.
Parameters are identified by their
command string and index. The index is used when
accessing a parameter over SynqNet. Drive parameters are implemented for particular drive
models and firmware versions.
NOTE: Supported parameters for a drive may be different, depending on the version of
firmware.
The MPI library contains a general drive parameter interface that is able to handle any set of
drive parameters, independent of the MPI library version. It uses a drive parameter map file to
determine the valid drive parameters. Individual drive parameters can be set (or read) using
MPI methods or with the sqDriveParam Utility. A list of drive parameters can also be set (or
read) using MPI methods or with the sqDriveConfig Utility.
The following sections describe the syntax of utilities used when accessing parameters. These
utilities are typically executed from a DOS window in the XMP\bin\WinNT directory.
