Bit 10, Not in operating range/Frequency limit OK
In the case of bit 10 = "0", the output frequency is
outside the limits set in parameter 225 and para-
meter 226 (Warnings: frequency low or frequency
high).
In the case of bit 10 = "1", the output frequency is
within the indicated limits.
Bit 11, No operation/Operation
In the case of bit 11 = "0", the motor does not turn.
In the case of bit 11 = "1", the frequency converter
has a start signal, or the output frequency is higher
than 0 Hz.
Bit 12, VLT OK/Stopped, autostart
In the case of bit 12 = "0", there is no temporary
overloading of the inverter.
In the case of bit 12 = "1", the inverter has stop-
ped due to overloading. However, the frequency
converter has not switched off (trip) and will start
again after the overloading has ended.
Bit 13, Voltage OK/Limit exceeded
In the case of bit 13 = "0", the voltage limits of the
frequency converter are not exceeded.
In the case of bit 13 = "1", the direct voltage in the
intermediate circuit of the frequency converter is
too low or too high.
Bit 14, Moment OK/Limit exceeded
In the case of bit 14 = "0", the motor current is be-
low the moment limit selected in parameter 221.
In the case of bit 14 = "1", the moment limit selec-
ted in parameter 221 is exceeded.
Bit 15, Timer OK/Limit exceeded
In the case of bit 15 = "0", the timers for the ther-
mal motor protection and thermal VLT protection
(description on page 67) have not exceeded 100%.
In the case of bit 15 = "1", one of the timers has
exceeded 100%.

Bit 00/01
The bits 00 and 01 are used to choose between
the four preprogrammed reference values (para-
meters 215-218)
according to the following table:
Progr. ref. val.
Bit 02, DC brake
Bit 02 = "0" leads to direct voltage braking and
stop. Braking current and duration are set in para-
meter 125 and 126.
Bit 02 = "1" results in Ramp.
