Description
SetTraceVariable
assigns the given variable to the specified
variableNumber
location in the trace buffer.
Up to four variables may be traced at one time.
All variable assignments must be contiguous starting with
variableNumber
= 0.
GetTraceVariable
returns the variable of the specified
variableNumber
.
Example:
To set up a three variable trace capturing the motor command, phase angle, and phase A
current, the following commands would be used:
SetTraceVariable 0 7
SetTraceVariable 1 29
SetTraceVariable 2 31
SetTraceVariable 3 0
Restrictions
When retrieving the traced variables from the list above the scaling may depend on the type of Atlas
being used. See
Section 3.11.1, “Atlas Settings Defaults and Limits”
for scaling information. See also
for current loop, field oriented control, and motor output related variable
scaling.
