Note: A fault occurring leads to a switch-over to the "Fault" state.
A fault can only be acknowled
ed 15 seconds after the occurrence of the
fault, as a blocking time is active internally.
The Warning bit "Bit No. 7" can be set at any time. It displays an device-internal
warning message. The evaluation of the warnin
available is done by readin
out the
warning status with the parameter
Warnings 270.
The Remote bit "Bit No. 9" is set if the operation mode control via remote contacts
(
Local/Remote 412 = 2) has been set and the hardware release is available (S1IND
= 1). Only then can the frequency inverter be controlled via the control word.
The bit Reference value reached "Bit No. 10" is set when the reference value
specified has been reached. In the special case of power failure regulation, the bit is
also set if the power failure re
gulation has reached the frequency 0 Hz (see operating
instructions). For "Reference value reached“ there is a hysteresis (tolerance ran
e),
which can be set via the parameter
max. Control deviation 549 (see operatin
instructions).
The bit Limit value active "Bit No. 11" displays that an internal limit is active. This
can, for example, be the present current limit, the torque limit or the overvoltage
limit. All the functions lead to the reference value being quit or not reached.
The bit Warning 2 "Bit No. 15" reports a warning which leads to a fault switch-of
of the frequency inverter within a short time. This bit is set if there is a warnin
for
motor temperature, heat sink/inside temperature, Ixt monitoring or mains phase
failure.
