4.2.2 Configure outputs
Digital and PWM outputs
Three types of controller outputs can be distinguished:
•
high side digital outputs with and without diagnostic function
•
high side digital outputs with and without diagnostic function and additional PWM mode
•
PWM outputs which can be operated with and without current control function. Current-controlled
PWM outputs are mainly used for triggering proportional hydraulic functions.
WARNING
Property damage or bodily injury due to malfunctions possible!
Outputs which are operated in the PWM mode do not support any diagnostic functions and no ERROR
flags are set. This is due to the structure of the outputs.
The function OUT_OVERLOAD_PROTECTION is not active in this mode!
NOTE
If an output is switched off in case of a fault (e.g. short circuit) via the hardware (by means of a fuse),
the logic state created by the application program does not change.
To set the outputs again after removal of the peripheral fault, the outputs must first be logically reset in
the application program and then set again if required.
Output group Q0...Q4 (%QX0.0...%QX1.8)
If the group Q0...Q4 is used as PWM outputs, the diagnosis is implemented via the integrated current
measurement channels which are also used for the current-controlled output functions. Using the
function OUTPUT_CURRENT (
→
page 176 ) load currents ≥ 100 mA can be indicated.
This function can also be used for diagnosis when the outputs are used as digital channel (only for
load currents
≥ 100 mA).
