Parameters TH and TL
Note the information on parameter T in Chapter 4.3.2.
The pulse width TH and the interpulse width TL can be
provided by the actual value of another already-programmed
function. You can use the actual values of the following
functions:
•
Analog comparator (actual value Ax - Ay, see Chapter
4.4.18)
•
Analog trigger (actual value Ax, see Chapter 4.4.16)
•
Analog amplifier (actual value Ax, see Chapter 4.4.20)
•
Analog multiplexer (actual value AQ, see Chapter 4.4.26)
•
Analog ramp control (actual value AQ, see Chapter
4.4.27)
•
Analog math (actual value AQ, see Chapter 4.4.30)
•
PI controller (actual value AQ, see Chapter 4.4.28)
•
Up/down counter (actual value Cnt, see Chapter 4.4.13)
Select the required function by the block number. The
timebase is configurable. For information on valid ranges
and parameter defaults, refer to Chapter 4.4.1.
