Velocity_encoder_factor formula:
Velocity_encoder_factor=
notice that the samplefrequens is differens in MAC050-141.
Or as and object:
Velocity_encoder_factor=
The Velocity_encoder_factor in example 1 is calculated to:
Velocity_encoder_factor=
Example 2:
We have a MAC800 motor with 8000 counts/revolution and the same belt drive as in the
above example under Position_Factor. We want the user unit of the velocity to be in
mm/s. The parameters should be set as follows:
Object
6094h subindex 1
6094h subindex 2
The Velocity_encoder_factor in example 2 is calculated to:
Velocity_encoder_factor=
Acceleration_factor. (3) in section 4.3.39.
This factor is used to convert the user unit into the internal unit (counts/sec²).
The factor is adjusted via object 6097h.
Example 1:
We have a MAC800 motor with 8000 counts/revolution. We want the user unit of the
acceleration to be in RPM/s. The parameters should be set as follows:
Object
6097h subindex 1
6097h subindex 2
Acceleration_factor formula:
Acceleration_factor=
