1.2.2.4.1.4. Analysis Tab
Click Analysis to conduct detailed analysis of the drive module activity in terms
of bus volts and system current, along with the capability of simulating changes to
the system parameters.

If the time is increased, this error message often appears.
This time slice message may also appear as soon as you click Solution on the main
taskbar. In this case, clicking Yes or No still takes you to the Solution tab, but if
you click No, some pre-calculations are not performed.
This time slice message often appears if one of the motion cycles is a cam, which
often has very short time segments. In this case, click No to ignore the message.

Check these boxes to adjust the X- and Y-axis values for the plot.
Time Slice
The Time Slice variable sets the time interval for the Analysis display. Because the shunt switching action is
modeled during selection, this value needs to be very short to obtain an accurate shunt selection (0.1 ms, for
example). However, if the total cycle time is more than a few seconds, the calculation time may become excessive.
The time is equal to the longest axis cycle. In the case of a very long length of time, it is suggested that a longer time
slice be used for early checks, but a time slice of less 0.1 ms should be used for the final selection.
