The 3-Phase PM Synchronous Motor Vector Control utilizes PC master software for remote control
from a PC. It enables the user to:
Variables read by the PC master software as a default and displayed to the user are:
The profiles of required and actual speeds, together with the desired I
the Speed Scope window.
The course of quickly-changing variables can be observed in the Recorder windows, displayed by the
PC master’s Speed Scope. The Recorder can only be used when the application is running from
External RAM, due to the limited on-chip memory. The length of the recorded window may be set in
Recorder Properties => bookmark Main => Recorded Samples. The dedicated memory space is
defined in the appconfig.h file of the ExtRAM target. The recorder samples are taken every 125 sec.
The following records can be captured:
The PC master software Control Page is illustrated in
actual speeds can be seen in the Speed Scope window.
