Chapter 10:Development Aids

SimplIQ

hardware and software include a number of features that facilitate application

development:

The

SimplIQ

drive’s built-in simulation capability enables the user to develop

large parts of the application from the desktop, without even connecting the

SimplIQ

drive to a motor.

Controller sampling time can be optimized for best performance.
The recorder is a major tool for viewing signals and debugging an application.

10.1. The Recorder

The

SimplIQ

drive recorder enables the user to record up to eight signals

simultaneously. The recorded signals can be uploaded to the host through the
communication connection, for presentation and analysis.

SimplIQ

drives operating

with CAN have two communication lines: CAN and RS-232. This arrangement enables
the recorder to use one line for performance monitoring while the machine host uses
the other line to control the

SimplIQ

drive in its normal context.

This section explains how to define the recorder parameters for the

SimplIQ

drive, how

to launch and trigger the recorder and how to fetch the recorded data.

Under most circumstances, this command is used only by the Composer or by

the tuning environment.

For implementations with separate motion processor, the

SimplIQ

drive and the

motion processor have a separate, independent recorder for each. The AR[1]
command selects which recorder is addressed by the recorder commands.

The list of recordable signals supported by the

SimplIQ

drive is stored internally and

can be retrieved by the host. (Refer to the LS and LP commands in the

SimplIQ for

Steppers

Command Reference Manual.) In addition, the

SimplIQ

drive can record user-

program variables for tracing the progress of user programs without interrupting
them.

The following commands are relevant to the recording process:

Command Description

BG, BT, IL[N]

Begins motion using software or hardware command. Start of
motion may be used to trigger the recorder.

BH

Uploads recorder results.
