4.15.5.9.4.2 Setting the output configuration
Name:
Output configuration 1 - 2 ConfigOutput01
Each channel can be configured for either "digital" or "analog" operation in this register. The corresponding
DigitalOutput or AnalogOutput registers must be written depending on the setting.

4.15.5.9.4.3 Shift switching pattern
Name:
ShiftOutput01 to ShiftOutput02
To prevent load peaks due to simultaneous switching of outputs, this register can be used to shift the switching
pattern by a number of full waves. Due to the hardware used, it is not possible to shift by less than a full wave.
Values higher than 23 are limited to 23.
Data type
Value
Information
0
No shift
USINT
1 to 23
Size of the shift in number of full waves
Example
Set 0 on Channel 1 and 1 on Channel 2. With the same control value (see "Integrated full-wave control") this delays
the switching pattern of Channel 2 by one full wave.
4.15.5.9.5 Zero crossing status
Name:
ZeroCrossingInput
ZeroCrossingStatus
StatusInput01
Zero crossing detection uses a fixed filter time of 1 ms and a scanning frequency of 10 kHz. When a missing or too
short period is detected, control is switched off until at least 2 periods are detected correctly, and the status flag
is set accordingly. Control is offset by 2 ms from the negative half-wave until the next zero crossover is detected
correctly or another error occurs. This is normally at least one complete wave.
Monitoring is activated at the first zero crossover after being switched on.
Function model 0 - Standard only:
The "packed outputs" setting in the AS I/O configuration is used to determine whether all of this registers' bits should
be set up individually as data points in the AS I/O mapping ("ZeroCrossingInput" through "ZeroCrossingStatus") or
whether this register should be displayed as an individual USINT data point ("StatusInput01").
