E2 = K Vvsp
E2 = height deviation in mm
Q = carriage spacing in mm
V
vsp = preload factor (see following table)

Calculation example for E
2
Example: Type MNNL 42
Spacing K = 700 mm
Calculation: Type MNNL 42 results in a preload factor Vvsp of 0.00003
0.00003 x 700 mm = 0.021 mm
Comment: The deviations of E2 must not exceed 0.021 mm.
