Servomotor Installation
2.2.1 Orientation
The mounting orientation depends on the method that is used to install the servomo-
tor. The allowable mounting orientations are given in the follow table.
2.2.2 Installation Standards
The motor rated specifications (rated output, rated torque, and rated speed) are the
continuous allowable values at an ambient temperature of 40
°C when servomotors
are installed with heat sinks.
For more information on heat sinks, refer to Large-Capacity
Σ -V Series Product Cat-
alog.
If the heat sink is small, the temperature of the servomotor can increase greatly. If the
servomotor is surrounded by a case or if there are objects that generate heat near the
servomotor, the temperature of the servomotor can increase greatly.
Always check the temperature of the servomotor on the actual equipment before
actual operation.
