Nova 5 load curve
In the load curve, the coordinate origin is the center of the end flange, and X, Y represent the
distance between the gravity center of load and the robot flange in X and Y directions. According to
r =
√

2
+ 
2
, the value r corresponds to the vertical coordinate X, Y[cm] of the load curve, and
the abscissa Z[cm] represents the distance from the gravity center of the load to the robot flange in
Z direction. You can determine the working condition of the robot according to the statistical results.
For example, if the load is 3.8kg, X = 6cm, Y = 8cm, Z = 5cm, and you can get r = 10cm. The steps
for judgement are as follows:
 According to r =
√


+ 

, calculate r = 10cm.
 Select the corresponding curve according to the weight of the load. As the load is 3.8kg,
you need to find the curve of 4kg correspondingly.
 Determine a point according to the r and Z coordinates, and compare the positional
relationship between the point and the 4kg curve to judge the working condition. If the
point is below the curve, the model is proper, otherwise you need to select other models.
