Bit 10, Data not valid/Data valid
Tell the frequency converter whether to use or ignore the
control word.
Bit 10=’0’: The control word is ignored. Bit 10=’1’: The
control word is used. This function is relevant because the
telegram always contains the control word, regardless of
the telegram type. Turn off the control word if not wanting
to use it when updating or reading parameters.
Bit 11, Relay 01
Bit 11="0": Relay not activated.
Bit 11="1": Relay 01 activated provided that Control word
bit 11=36 is chosen in 5-40 Function Relay.
Bit 12, Relay 02
Bit 12="0": Relay 02 is not activated. Bit 12="1": Relay 02 is
activated provided that Control word bit 12=37 is chosen in
5-40 Function Relay.
Bit 13, Selection of set-up
Use bit 13 to choose from the 2 menu set-ups according
to the table.
Set-up Bit 13
1 0
2 1
Table 8.38
The function is only possible when Multi Set-Ups=9 is
selected in 0-10 Active Set-up.
Make
a selection in 8-55 Set-up Select to define how Bit 13
gates with the corresponding function on the digital
inputs.
Bit 15 Reverse
Bit 15=’0’: No reversing.
Bit 15=’1’: Reversing. In the default setting, reversing is set
to digital in 8-54 Reversing Select. Bit 15 causes reversing
only
when Ser. communication, Logic or Logic and is
selected.

Table 8.39
Explanation of the status bits
Bit 00, Control not ready/ready
Bit 00=’0’: The frequency converter trips.
Bit 00=’1’: The frequency converter controls are ready but
the power component does not necessarily receive any
power supply (in case of external 24 V supply to controls).
Bit 01, Drive ready
Bit 01=’1’: The frequency converter is ready for operation
but the coasting command is active via the digital inputs
or via serial communication.
Bit 02, Coasting stop
Bit 02=’0’: The frequency converter releases the motor.
Bit 02=’1’: The frequency converter starts the motor with a
start command.
Bit 03, No error/trip
Bit 03=’0’ : The frequency converter is not in fault mode.
Bit 03=’1’: The frequency converter trips. To re-establish
operation, press [Reset].
Bit 04, No error/error (no trip)
Bit 04=’0’: The frequency converter is not in fault mode. Bit
04=“1”: The frequency converter shows an error but does
not trip.
Bit 05, Not used
Bit 05 is not used in the status word.
Bit 06, No error/triplock
Bit 06=’0’: The frequency converter is not in fault mode. Bit
06=“1”: The frequency converter is tripped and locked.
