Depending on the specified setpoint, the power outputs are controlled with an equal number
of positive and negative half-waves (reference value: 200 half-waves).
To avoid excessively high inrush currents, the power outputs are switched on time-delayed.
See Switch on heating (Page 137).
A static table is used for control so that a too frequent change of the setpoints can result in a
significantly deviating setpoint. For this reason, the setpoints are only forwarded in a time
scale of ca. 600 ms.
Note
If it is required for an application that a changed setpoint value is applied immediately, you
can switch off this time grid (see Acyclic output data (Page 164)). When you disable the time
scale, you must ensure that the setpoints are not changed too frequently within the reference
period of 100 half-waves.
