6.10.5 Selection of
Encoder
Precondition for a good control behaviour of a drive is not least a question of the
selection and the correct connection of the encoder. This also includes the mechanical
as well as the electrical connection.
Max. operating frequency
(max.sampling frequency)
Depending on the max. operating frequency of the encoder input, the encoder and the
maximum speed of the drive the line number of the encoder can be selected.
6.9.4 Speed and line number in dependence on the max. operating frequency
of the encoder inputs
Speed n [rpm]
Line number z
The max. signal frequency, which is given out by the encoder, is calculated as follows:
n
max
[rpm] x z
60000
f
max
[kHz] =
f

: max. signal frequency
n

: max. speed
z: encoder line number
The following condition must be met:
