Description
Note:
This setting is only available in burst-firing operation mode.
For example, for a fixed period of 500 ms, 5 sine waves are
switched on and 20 switched off at an output level of 20 %.

The cycle time is variable with this setting. At the required out-
put level, the device attempts to find the shortest possible cy-
cle time for full sine waves. At an output level of 20 %, this re-
lates to one sine wave ON and four sine waves OFF.

100ms
Dependent on the cycle time setting.
At least three full sine waves are always let through.
At an output level of 50 % and with the fastest possible cycle
time,
3 sine waves are switched on and 3 switched off.

Note:
Particularly suitable for the control of transformer loads
Note:
This setting is available in continuous burst-firing operation
mode and in logic operation.
No: for resistive load
Yes: for transformer loads
If set to "Yes", the first half-wave of each pulse group is cut
with the set phase control angle α.
