If a fault occurs, the fault status is activated.
Note: A fault can only be acknowledged 15 seconds after the occurrence of the
fault, i.e. after the internal blocking time has elapsed.
If a fault has occurred, the cause of the fault can be read out via parameter Cur-
rent Error
260.
Status Word Bit 7 to Bit 15
Bit 7, "Warning bit"
The warning bit "7" can signal an internal warning and results in the frequency
inverter being switched off, depending on the cause.
The evaluation of the warning is done by reading out the warning status via parame-
ter
Warnings 270.
Bit 9, "Remote"
The "Remotebit" is set if the "Operation mode Control via remote contacts" is set
(
Local/Remote 412 = 2) and the external controller release is present. Only then can
the frequency inverter be controlled via the control word.
Bit 10, "Reference value reached"
The bit "Reference value 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 re
gulation reaches the frequency 0 Hz (see frequency inverter operating
instructions).
For "Reference value reached“ there is a hysteresis (tolerance range) which can be set
via the parameter
Max. Control Deviation 549 (see frequency inverter operating
instructions).
Bit 11 "Limit active"
The bit Limit value active indicates that an internal limit is active. This may be the
current limit, the torque limit or the overvolta
ge control. All functions result in the
reference value being left or not reached.
Bit 15 "Warning2"
The bit "Warning2" extends bit 7 "Warning bit" by the following information:
Bit 15 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 warnin
g
relating to the motor temperature, heat sink/inside temperature, Ixt monitoring or
mains phase failure.
If bit 15 is set, bit 7 is set, too.
