Next select the new baud-rate using the Properties button (see Figure 2).

When the Composer Smart Terminal re-opens, you may use the SV command to
make the new baud setting permanent.

2.2 Application Parameters and Programming

When you commission a drive, you create an Application. An Application refers
to the entire data set you download and store into the drive. The application
includes:

Parameters to store permanently in the drive, such as controller coefficients.
User programs: please refer to the SimplIQ Programming and Language Guide.

The Composer packs all the non-volatile parameters and the User Program in a
single file, with the .dat extension.

The Composer can later use this .dat file to program many amplifiers to the same
parameters and User Program.

2.2.1 Flash, RAM and Tables

The drive contains the following memory types:

Memory Type

Used

for

Serial Flash

Non-volatile

This flash stores all the non-volatile
parameters, as well as the User Program

Table Flash

Non-Volatile

This high speed flash stores the motion
correction tables for real-time use.
The data in the Table Flash must be an
identical copy of the data in the serial flash.

RAM

Volatile

Stores a volatile copy of the serial-flash
parameters for real-time high-speed use.

When the drive powers-on, it loads the RAM as a copy of the table flash.

It also compares the Table Flash with the Serial Flash. If the contents are not-
equal, you will not be able to start the motor until the situation is corrected.

When you communicate with the drive the parameters you modify are in the
RAM. When you write, for example, KI[1]=1, you update the copy of KI[1] in the
RAM. The parameter KI[1] has a copy in the serial flash which remains as is.

When you want to synchronize the RAM and the serial flash, you can:

Use the SV command to copy the entire RAM contents into the serial flash (for

example, after you tuned some parameters).
