Example
When you configure a channel with 5000 Hz (
≙
200
μs) and the user program writes the
value 3 to the output word of the channel, this value is converted to 0 by the module: The
channel is permanently 0.
"Diagnostics: Overflow" parameter
You use the "Diagnostics: Overflow" parameter to enable the diagnostics if the permitted
value range of the duty factor is exceeded, which means an output value > 1000 from the
user program is written to the output word of the channel.
"Substitute value duty factor" parameter
You use the "Substitute value duty factor" parameter (0 to 1000) to specify the pulse/pause
duty factor of the pulse width modulation in the case of a CPU STOP.
Derating
See the information on derating of the module in the section Derating of the
DQ 4x24VDC/2A HS (Page 36).
