Mass load for linear drives and piston rod cylinders
Determine the permitted mass load based on Tab. 3/1:
Mounting position Maximum mass load Minimum mass load
horizontal ( á = 0°) m
max
0.1 * m
max
vertical ( á = 90°) 0.33 * m
max
0.1 * m
max
diagonal (0° < á < 90°) (1−2/3 sin) * m
max
0.1 * m
ma
á = Mounting position in [°]
m
max

d = Cylinder diameter [mm]
P

= Supply pressure [bar]
m

Mass moment of inertia for rotary drives
The mass moment of inertia must not change during the
movement. Permitted mass moments of inertia for rotary
module type DSMI−... in electronically regulated operation
with the SPC200 are shown in the following table:
Rotary module Permitted mass moment of inertia
[kgm
2 * 10 −4 ]
DSMI−25−... 15 ... 300
DSMI−40−... 60 ... 1200
Tab. 3/2: Permissible mass moment of inertia
Festo supports you in calculating the mass moment of inertia
with the MTM calculation program (Internet: http://www.
festo.com). This program serves for calculating the mass moĆ
ments of inertia of the 2nd degree for various basic units and
standard parts from Festo (e.g. clip−on flange for DSMI−...).
