FIGURE 5-7 Defining belt scale parameter parameter
5.5.1 DR 5 – Nominal speed
The nominal speed of the belt corresponds with the speed at nominal
conditions, i.e. at nominal load on the belt. This is output in LU (length
units) per second e.g. 1.7 m/sec.
5.5.2 DR 5 – Time basis for the belt speed
The belt speed is output in LU (length units) per second. The measuring
time of the pulse input can be set to another time e.g. 2 seconds. That
