5.6 Expansion Mod. MAC00-FC2/FC4/FC41
Or as and object:
Acceleration_factor=
notice that the samplefrequens is differens in MAC050-141.
The Acceleration_factor in example 1 is calculated to:
Accelerationr_factor=
Example 2:
We have a MAC800 with 8000 counts/rev. and the same belt drive as in the above ex-
ample under Position_Factor. We want the user unit of the acceleration to be in mm/s².
The parameters should be set as follows:
Object
6097h subindex 1
6097h subindex 2
The Acceleration_factor in example 2 is calculated to:
Accelerationr_factor=
Feed_constant_factor.
Feed_constant_factor formula:
Feed_constant_factor=
