def cnvtol(self, lab="", value="", toler="", norm="", minref="", **kwargs):
    """Sets convergence values for nonlinear analyses.

    APDL Command: CNVTOL

    Parameters
    ----------
    lab
        Valid convergence labels. If STAT, list the status of the currently
        specified criteria.

    value
        Typical reference value for the specified convergence label (Lab).

    toler
        Tolerance; defaults to 0.005 (0.5%) for force and moment, 1.0E-4
        (0.01%) for DVOL, 0.05 (5%) for displacement when rotational DOFs
        are not present, and 0.05 (5%) for HDSP.

    norm
        Specifies norm selection:

        2 - L2 norm (check SRSS value). Default, except for Lab = U.

        1 - L1 norm (check absolute value sum).

        0 - Infinite norm (check each DOF separately). Default for Lab = U.

    minref
        The minimum value allowed for the program calculated reference
        value. If negative, no minimum is enforced. Used only if VALUE is
        blank. Defaults to 0.01 for force, moment, and volume convergence,
        1.0E-6 for heat flow, 1.0E-12 for VLTG and CHRG, 1.0E-6 for HDSP,
        and 0.0 otherwise.

    Notes
    -----
    This command is usually not needed because the default convergence
    criteria are sufficient for most nonlinear analyses. In rare cases, you
    may need to use this command to diagnose convergence difficulties.

    Values may be set for the degrees of freedom (DOF) and/or the out-of-
    balance load for the corresponding forcing quantities.

    Issuing CNVTOL to set a convergence criterion for a specific
    convergence label (Lab) does not affect the convergence criterion for
    any other label. All other convergence criteria will remain at their
    default setting or at the value set by a previous CNVTOL command.

     When the GUI is on, if a "Delete" operation in a Nonlinear Convergence
    Criteria dialog box writes this command to a log file (Jobname.LOG or
    Jobname.LGW), you will observe that Lab is blank, VALUE = -1, and TOLER
    is an integer number.  In this case, the GUI has assigned a value of
    TOLER that corresponds to the location of a chosen convergence label in
    the dialog box's list.  It is not intended that you type in such a
    location value for TOLER in an ANSYS session.  However, a file that
    contains a GUI-generated CNVTOL command of this form can be used for
    batch input or with the /INPUT command.

    Convergence norms specified with CNVTOL may be graphically tracked
    while the solution is in process using the ANSYS program's Graphical
    Solution Tracking (GST) feature.  Use the /GST command to turn GST on
    or off.  By default, GST is ON for interactive sessions and OFF for
    batch runs.

    This command is also valid in PREP7.
