The transmission of the encoder value occurs either in a frame together with the setpoint
(frame 3 or frame 5), or in a separate encoder frame (frame 81 or frame 83).
The following figure represents the relationship between the technology objects and the
drives / encoders:
Explanation of the figure:
● The setpoint of a speed axis is transmitted to a drive via PROFIdrive frame 1, 2, 3 or 5.
● The encoder value of an external encoder is transmitted via PROFIdrive frame 81 or 83.
● The setpoint of a positioning axis/synchronous axis is transmitted to a drive via
PROFIdrive frame 1, 2, 3 or 5
● Encoder value of the positioning axis/synchronous axis
The encoder value can be transmitted in the following PROFIdrive frames:
– Transmission in the same PROFIdrive frame, in which the setpoint is also transmitted.
For example, with PROFIdrive frame 3 or 5
– Transmission in PROFIdrive frame 81 or 83.
