# Mount Limits Block

The [MOUNT_LIMITS] block stores the parameters for mount limits. You can use commas, white spaces or tab characters to separate the data values. The solver obtains the mount limits for a model through the IMPACT function. You can specify limits in the positive and negative travel directions for all 6 directions: X, Y, Z, AX, AY and AZ. For each direction, you specify five parameters.

The following table describes the type and dimension for the input parameters. Abbreviations are [A] = angle dimension, [F] = force, [L] = length, [T] = time.
Parameter Type Translational Units Rotational Units
K Real [F][L-1] [F][L-1][A-1]
E Real - -
C Real [F][T][L-1] [F][L][T][A-1]
D Real [L] [A]
L Real [L] [A]
