(5) Average power consumption of the input section of the input
module
(Power consumption for simultaneous ON points)
W
IN = IIN E Number of input points Simultaneous ON rate [W]
I
IN : Input current (Effective value for AC) [A]
E : Input voltage (Voltage in actual use) [V]
(6) Power consumption of the external power supply section of the
intelligent function module
W
S = I5V 5 + I24V 24 + I100V 100 [W]
The total of the power consumption values calculated for each block is the power
consumption of the overall sequencer system
W = W
PW + W5V + W24V + WOUT + WIN + WS [W]
From this overall power consumption [W], calculate the heating value and a rise
in ambient temperature inside the panel.
The outline of the calculation formula for a rise in ambient temperature inside the
panel is shown below.
T=

[ C ]
W : Power consumption of overall Motion system (value obtained above)
A : Surface area inside the panel [m

]
U :
When the ambient temperature inside the panel is uniformed by a fan ...... 6
When air inside the panel is not circulated.............................................. 4
POINT
If the temperature inside the panel has exceeded the specified range, it is
recommended to mount a heat exchanger to the panel to lower the temperature.
If a normal ventilating fan is used, dust will be sucked into the Motion controller
together with the external air, and it may affect the performance of the Motion
controller.
