8.2 Mounting to the Machine
• Allowable Loads
When you connect a load to the Servomotor, do not place a load on the rotating part that exceeds the
allowable limits. If you exceed the allowable limits, the service life of the bearings will be reduced and
the rotating part will be damaged.
Refer to the specifications for each type of Servomotor for the allowable loads on the rotating part of
the Servomotor.
Note
8-6
• The allowable loads that are given in the specifications include the static load in one direction
and the dynamic load that occurs during rotation. Consider the dynamic load when you select
a Servomotor or design the equipment.
•
When designing a system for a SGM7D Servomotor, multiply the allowable load by the following
safety coefficient depending on the type of load.
Type of Load
Smooth load with no shock
Light repetitive load
Shock load
