Output LEDs
The LED of an output, which is supplied with power, is yellow. For example you
have switched the output Q4, so the LED
Q4
lights up:
If the voltage at the switched output is not detected, the LED does not shine. Make
sure that ground (
GND
) and the power supply for the outputs (
US
Q
OK
) are
connected.
10.5.2
Analog Output
Set output voltage values are retained when changing from RUN to STOP and
are not set to 0.
The maximum switching frequency, i.e. the change between two values, is 200
Hz. The switching frequency depends on two factors: the task cycle time, in which
the analog output is set, and the set alternating frequency, with which the output
changes between the values.
Example:
▪ Task cycle time = 1 ms in which the output is set (frequency)
▪ Set alternating frequency = 5 ms 0 V (Low signal) and 5 ms 10 V (High signal)
corresponds to a frequency of 100 Hz
