3.3.3 Calculating Motion Controller Heat Generation
The ambient temperature inside the panel storing the Motion controller must be
suppressed to the specified ambient temperature of 55°C(131°F) or less.
For the design of a heat releasing panel, it is necessary to know the average power
consumption (heating value) of the devices and instruments stored inside. "Use the
"Power consumption" on section 2.5.2 "MR-MQ100 hardware and wiring" (1) Unit
specification. From the power consumption, calculate a rise in ambient temperature
inside the control panel.
