Thus, the calculation formula of velocity factor 1 is below:
Load speed:
Load speed = Motor speed × Lead pB = 1200 rpm ×
10 mm

6
It indicates that 1 mm/s of load speed corresponds to 6 rpm of motor speed.
Thus, the numerator 6095-1h can be set to 1, and the denominator 6095-2h can be set to 6.
(3) Acceleration factor (6097h)
Acceleration factor refers to the motor acceleration speed (unit: rpm/ms) corresponding to the load acceleration
speed of one user unit.
Acceleration factor consists of the numerator 6097-1h and the denominator 6097-2h, through which a relation
between the load acceleration speed (user unit) and the motor acceleration speed (motor unit) can be formulated as
below:
Acceleration factor (6097h) =
Numerator of acceleration factor (6097
−
1h)
Denominator of acceleration factor (6097
−

Acceleration factor =

For the ball screw:
 Acceleration speed of load: 40 mm/s
2
 Lead pB=10 mm/r
 Motor encoder PPR 2500, actual resolution: P=10000 (p/r)
Thus, the calculation formula of acceleration factor is below:
Motor acceleration speed:
