Explanation
Switches the active power control on or off
When the active power control is switched on, the active
power setpoint is being implemented gradually in accordance
with your additional settings in the group Settings for active
power control.
When the active power control is switched off, the active
power setpoint is implemented immediately.
Indicates the time interval at which the control command with
the new output value is to be sent to the inverters once the set-
point sent by the signal generator changes
The first output value is sent to the inverter immediately after the
setpoint is changed. If additional output values are required in
order to reach the setpoint, these will be sent at the specified
time interval. This enables, for example, an incremental in-
crease in the active power.
Indicates the maximum change in percentage points per time
interval that occurs once an active power limitation setpoint has
been canceled
Indicates the maximum change in percentage points per time
interval that occurs once an active power limitation setpoint has
been received
