7.5.11 DT1 element
Purpose
The DT1 element is to differentiate signals.
It can, for instance, be used for acceleration compensation (dv/dt).

FIG 7-45 1st order derivative element (DT1 element)
1. Input
With the function ”freely assignable analog inputs” each input can be assigned to
a ”terminal signal” from the table in C145.
2. Outputs
With the function ”freely assignable analog inputs” the outputs can be assigned to
the targets listed under C146. The same signal is assigned to both outputs. The
output signal is limited to max. 200%.
3. Function
The gain K is set under code C650, the delay time Tv is set under C651. The input
sensitivity of the DT1 element can be reduced under C653, i.e. according to the
settings, only the high-value bits indicated are evaluated.
