Velocity encoder factor
This factor is used to convert the user unit into the internal unit (RPM).
The factor is adjusted with the object 6094h.
Example 1:
An MIS232 has1600 counts/revolution.
We want the user unit of velocity to be in RPM. This is the same as the internal unit.
The parameters should be set as follows:
Object
6094 subindex 1
h
6094 subindex 2
h
Example 2:
We have an MIS232 that uses RPM as the internal velocity and the same belt drive as in
the above Position factor example.
We want the user unit of velocity to be in mm/s.
The parameters should be set as follows:
Object
6094 subindex 1
h
6094 subindex 2
h
Acceleration factor
This factor is used to convert the user unit into the internal unit (9.54 RPM/s).
The factor is adjusted with the object 6097h.
Example 1:
We have an MIS232 with 1600 counts/revolution.
We want the user unit of acceleration to be in RPM/s.
The parameters should be set as follows:
Object
6097 subindex 1
h
6097 subindex 2
