631 Digital Servo Drive 07-01-08-02-E-V0500
Minimum Air Clearances
Cubicle Size
The digital servo drive is protected against damage caused by overheating.
There is a thermal sensor installed on the heat sink. When the temperature rises to >95°C, the
drive is automatically switched off. This setting cannot be changed. Use a cabinet of the correct
size for adequate air circulation, see below.

Ventilation
The servo drive gives off heat in normal operation and must therefore be mounted to allow the
free flow of air through the ventilation slots and heatsink. Maintain minimum clearances for
ventilation as shown below to ensure heat generated by other adjacent equipment is not
transmitted to the Servo Drive. Be aware that other equipment may have its own clearance
requirements. When mounting two or more 631s together, these clearances are additive.
Ensure that the mounting surface is normally cool.

General Rule:
It is better to place heat-producing devices low down inside an enclosure to support internal
convection, which will spread the heat. If placing devices up high is unavoidable, you should
consider increasing the (upper) dimensions of the cubicle, or installing fans.
