[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. 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 3 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
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”
� There are some restrictions as shown in Table 1 in the matching of SCARA Robots of
XSEL-RDX/SDX (three-phase type).
