Register controller does not follow the setpoint

Question:

Why does the slave not follow the selected speed setpoint in spite of correctly set code digit C1300, but works in an integer relation to this?

Answer:

The cause is a mismatch of the function block DFIN in the slave (register controller).

Code digit C0425 in the slave is to be set to 16384 Increments/revolution (selection -6-).

The assignment between the setpoint of the master and the slave's speed is not done in the DFIN block but only in code digits C1300 and 1301. In C 1300 the LSF (Line Shaft Format) is set, which indicates the transported quantity of the material per revolution of the master encoder. In C 1301 the master encoder's number of pulses per revolution is set.
