d) Speed signals N1, N2, N-U, R/L (No. 1, 3, 7, 9)
The connection housing DF2 has 4 connections
for speed output:
- Two square-wave signals shifted by 90
degrees (N1, N2)
- A scalable voltage output (N-U) with direction
signal (R/L)
Illustration 15
Outputs N1 and N2
Each of the speed outputs N1 and N2 provide a square-wave signal with a resolution of 2x450 periods per
revolution (illustration 16).
Illustration 16
The speed is calculated as follows:
N [rpm] = f [Hz] / 7.5
The speed channel signals N1 and N2 have a phase shift of 90 degrees to each other. Depending on the
rotational direction one of the two signals leads 90° in phase (illustration 17).
