Example 1 of the calculation of the dimension factor
The drive speed is given in m/s. The conversion ratio is 0.01 m per revolution of the motor (Note: face value
factor = 1).
The dimension factor is calculated from
Dimension factor =
output (rpm)
input (here: m/s)
for01
0.01 m corresponds to 1 revolution of the motor shaft
0.01 m/min corresponds to 1/min
0.01 m/60s corresponds to 1/min

When calculating the dimension factor, units should not be shortened (1 min is not shortened as 60 s)

Example 2 of the calculation of the dimension factor
The reference values for a bottling plant are given in bottles per minute. One revolution of the drive corresponds
to the filling of 0.75 bottles. This corresponds to a dimension factor of 4/3. The speed limitation and the ramp
function are also given in bottles per minute

Example of the face value factor
Normally the reference value has a resolution of 1 rpm. In order to exploit the available resolution, the face
value factor is used.
The motor speed range required is, for example, 0...1500 rpm. A more accurate resolution (i.e. 1/4 revolution)
can be obtained by setting hte face value factor to 1/4.
The value 4 000 is entered, for example, in order to select 1000 rpm This is then multiplied with the face value
factor to give the value 1000 rpm.
