Figure 101: easy800 circuit diagram with pulse width modulation.
Parameter display and parameter set for pulse width
modulation:
The parameter display for a timing relay is used to modify the
period duration, the minimum on time and the enabling of
the parameter display.
Value and time ranges
Inputs
The function block inputs
>SV, >PD and >ME can be
assigned the following operands:
•Constants
• Markers MD, MW, MB
h
To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram.
