Parameter
The pulse width TH and the interpulse width TL can be provided by the actual value of another
already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller:AQ
Data latching relay: AQ
Up/Down counter: Cnt
The value of
＂ＴＨ＂，＂ＴＬ＂
can be set/modified in parameter mode. For information about
how to modify, refer to chapter 5.2.2 please.
