4.15.13.10.7.2 Setting the switch-off time
Name:
ConfigOutput01 to ConfigOutput04
This register defines how far in front of the zero cross-over the internal control signal for the TRIAC is switched off.
Increasing this value may be necessary in order to prevent unwanted firing of the TRIAC in the event of a slight
disturbance in the mains frequency.
With smaller loads, it is important to ensure that this switch off value is not set to large (too early) to prevent
switching off prematurely.
The triac can of course only be fired before the set switch-off time.
"SwitchOffValue" in the AS I/O configuration.
