6.4.3.2.1 Velocity format
Indicates the resolution at which the velocity is calculated and output.
The velocity is output signed, as a two's complement:
● Counting direction setting = forward
– Output positive, with clockwise rotation
(looking at flange connection)
● Counting direction setting = backward
– Output negative, with clockwise rotation
(looking at flange connection)
If the velocity value range (-2147483648…+2147483647) is exceeded or not reached, the limit values
(0x7FFF FFFF or 0x8000 0000) are output.

6.4.3.2.2 Velocity filter intensity
Using the Velocity filter intensity parameter, the output velocity can be averaged. The
parameter serves to setup a lowpass filter working on the measuring system’s actual velocity value.
Higher intensity values allow stronger filtering yielding to lower cut-off frequencies. High acceleration
motion profiles require lower filter intensities. Refer to the following described parameter Velocity
filter type, for a dynamic filter engagement according to the current motion status.
