[2] Power Capacity and Heating Value
Calculate the Power Capacity and Heating Value using the following formulas.
Rated Power Capacity [VA]=Total Capacity of Motor Power [VA]+Total of the power
consumption at the control part [VA]
Heating Value [W]=Total Output Loss [W]+(Total of internal power consumption [VA]
×0.7(Efficiency)×0.6(Power factor))
� Select the motor power capacity [VA] from Table 2 and Table 3. However, please note
that the motor power capacity at the acceleration and deceleration is 3 times higher at
most. (2 times higher max. for motor wattage 600W)
� Figure out the total of the power consumption at the control part [VA] with the total of
power of the actually mounted components × quantity, by selecting the applicable ones
from Table 4 Control Power Source (Internal Consumption and External Consumption).
� To calculate the sum total of output loss [W], refer to the “Output Loss” column in Table
2 and Table 3 below and select the values corresponding to the output losses of each
connected actuator.
� For the inner power demand (VA) for calculating the heating value (W) in the control unit,
select the components which are being placed, from the columns of Control Power
Supply (Internal Consumption) and External Power Supply (Internal Consumption) in
Table 3 and calculate it using the formula “Power {SYMBOL} Quantity of the Placement
Component”
� For XSEL-RX/SX (3-phase type), there are restrictions in the total wattage of the
single-axis actuators that can be added as shown in Table 1.
