Bit no. 7, Warning, can be set at any time. It indicates a device-internal warning
message. The evaluation of the present warning is carried out by reading out the
warning status with parameter
Warnings
270.
Bit no. 10, Target reached, is set when the specified reference value has been
reached. In the special case of power failure regulation, the bit is also set if the power
failure regulation has reached the frequency 0 Hz (see operating instructions). For
"Reference value reached“ there is a hysteresis (tolerance range), which can be set
via parameter
max. Control deviation
549 (see operating instructions).
Bit no. 11, Internal limit active, indicates that an internal limit is active. This can,
for example, be the present current limit, the torque limit or the over-voltage limit. All
of these limit functions lead to the reference value being quit or not reached.
Bit no. 15, Warning 2, indicates a warning which leads to a fault switch-off of the
frequency inverter within a short period of time. This bit is set if there is a warning for
motor temperature, heat sink/inside temperature, Ixt monitoring or mains phase fail-
ure.
