Hi,
Please check the MODSELOPTION command also.

You need to define the limit in the MXPAND command itself. Ansys Help page says:
"If dir1 = YES, then any mode in this direction is expanded if its modal effective mass divided by the total mass (modal effective mass ratio) is greater than SIGNIF on the MXPAND command."
