2.9.  Heat Radiation and Installation 
Since the controller and motor generate heat, their heat radiation should be considered carefully. 
Generated heat depends on the operating conditions. Determine a heat radiation method according to 
the operating conditions. 
The controller and motor have a temperature detection sensor (thermistor) in the heat generating 
section. As a safety function, the thermistor stops control if the detector temperature reaches: 
Controller About 
70ºC 
Motor About 
70ºC 
(For details, see 10.1.   “Safety Functions”) 
The controller and motor require heat radiation so that their temperatures will not exceed the above values. 
 
Controller installation methods 
The controller can be installed by either method A or B below. 
At installation, put the controller frame in contact with a heat-radiating structure (heat sink or cabinet). 
Method A has higher heat radiation efficiency. However, select either method by considering the 
operating conditions and cable routing. When installing the controller frame, apply thermal grease or 
attach a thermal conductive sheet to the contact surface. 
Under some operating conditions, forced air cooling by a fan is necessary. Cool the heat-radiating 
structure (heat sink or cabinet) and the controller.
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition to the output amplifier, the control circuit section (DSP) generates heat. 
Allow as much space as possible around the equipment. 
 
 
   
Caution 
 
 
The controller becomes hot during operation.
