"x" means any value.
Bit 7 "Warning" can display a device-internal warning message at any time. The cur-
rent warning is evaluated by reading the warning status with parameter
270.
ings
Bit 10 "Target reached" is set when the specified reference value is reached. In the
special case of power failure regulation, the bit is also set when the power failure reg-
ulation reaches the frequency 0 Hz (see frequency inverter Operating Instructions).
For "Target reached", there is a hysteresis (tolerance range) which can be set via the
parameter
Bit 11 "Internal limit value active" indicates that an internal limit is active. This
may be the current limit, the torque limit or the overvoltage control. All functions will
result in the reference value being left or not reached.
Bit 15 "Warning 2" signals a critical operating state which will result in a fault switch-
off of the frequency inverter within a short time. This bit is set if there is a delayed
warning relating to the motor temperature, heat sink/inside temperature, Ixt monitor-
ing or mains phase failure.
