Note:
Subordinate control loop cannot be modified!
The half-wave control operating mode is only compatible with
single-phase power controller operation. It is a special type of
phase-angle operation mode used, for example, for vibrating
magnets. In half-wave control, one thyristor branch remains
permanently locked so that only the positive half-wave is al-
lowed to pass through.
The specified setpoint value is converted to a phase control
angle of 180 °el. to 0 °el.
In this operating mode, neither load voltage nor load current
can be measured, which makes a subordinate control loop im-
possible.
