10.530 (ID 1913) Line Freq
Location in the menu:
(P2.13.3.1)
(Multi-purpose Control Application)
Use this parameter to set the grid Nominal Frequency. With unbalanced grid voltages, a resonance-like oscillation can occur if the
motor frequency matches the grid frequency.
10.531 (ID 1914) Line Freq Hysteresis
Location in the menu:
P2.13.3.2
(Multi-purpose Control Application)
Use this parameter to set the hysteresis of the grid Nominal Frequency. With unbalanced grid voltages, a resonance-like oscillation
can occur if the motor frequency matches the grid frequency. Stator winding monitoring is not used in the hysteresis area.
10.532 (ID 1940) Fault Warning Indication
Location in the menu: P2.7.49
Use this parameter to select how warning and fault indications are transmitted to digital outputs and to the fieldbus.

The warning or fault signal is active as long as the warning or fault is active. A warning will disappear 10 second after
the warning situation has passed. A fault always requires a reset.
