7.10.3. Build-in output - PWM ( Pulse-width modulation) mode for SSR relay output
Technical specifications of SSR relay can be found in Appendices 8.12. S8, S16, S24 -
SOLID STATE RELAY DRIVERS MODULES
Built-in outputs parameters in PWM mode are:
– Name – each outputs already has a name given by the device and user cannot
change it - see
Fig. 7.78
,
–
Mode=PWM
– this parameter allows the user to select method of operation the
output,
– Source – this parameter contains a Logical channels list, where the selected
logical channel will be a data source for this built-in output (see Fig. 7.79 ),
– Levels parameter block - these parameters allow the user to set the range of the
input signal which will change the duty cycle of the output signal, is discussed below
in this
Chapter
,
– Timing parameter block - these parameters allow the user to set the timing
parameters of the output signal, is discussed below in this Chapter ,
Levels parameter block
The parameters are:
–
Lower level
and
Upper level
- by setting these parameters the range is defined
within which the change duty cycle of pulse depending on the source signal; below
this range the signal is zero (zero width, zero duty cycle) and above this range the
signal is completely filled (fully on of the cycle period) (see
Fig. 7.87 ),
– Alarm level - when the data source for the built-in output returns Error state or the
range being exceeded: the low -Lo- state and high -Hi- state, Alarm level parameter
for the PWM mode allows setting the duty cycle of the output signal in time of alarm
state according to the parameters of
Lower level
and
Upper level
,
