Bit 03, No trip/trip:
Bit 03 = '0' means that the frequency converter is not
in fault mode.
Bit 03 = '1' means that the frequency converter is trip-
ped, and that it needs a reset signal for operation to be
reestablished.
Bit 04, Not used:
Bit 04 is not used in the status word.
Bit 05, Not used:
Bit 05 is not used in the status word.
Bit 06, Not used:
Bit 06 is not used in the status word.
Bit 07, No warning/warning:
Bit 07 = '0' means that there are no warnings.
Bit 07 = '1' means that a warning has occurred.
Bit 08, Speed ref/speed = ref.:
Bit 08 = '0' means that the motor is running, but that
the present speed is different from the preset speed
reference. It might, for example, be the case while the
speed is being ramped up/down during start/stop.
Bit 08 = '1' means that the motor's present speed is the
same as the preset speed reference.
Bit 09, Local operation/serial communication control:
Bit 09 = '0' means that [STOP/RESET] is activated on
the control unit, or that
Local control
in parameter 002
Local/remote operation
is selected. It is not possible to
control the frequency converter via serial communica-
tion.
Bit 09 = '1' means that it is possible to control the fre-
quency converter via serial communication.
Bit 10, Outside frequency range:
Bit 10 = '0', if the output frequency has reached the
value in parameter 201
Output frequency low limit
or
parameter 202
Output frequency high limit
. Bit 10 = "1"
means that the output frequency is within the defined
limits.
Bit 11, Running/not running:
Bit 11 = '0' means that the motor is not running.
Bit 11 = '1' means that the frequency converter has a
start signal or that the output frequency is greater than
0 Hz.
Bit 12, Brake test:
Bit 12 = '0' means brake test OK.
Bit 12 = '1' means brake test failed.
Bit 13, Voltage warning high/low:
Bit 13 = '0' means that there are no voltage warnings.
Bit 13 = '1' means that the DC voltage in the frequency
converter's intermediate circuit is too low or too high.
Bit 14, Torque OK/ above limit:
Bit 14 = '0' means that the motor current is lower than
the torque limit selected in parameter 221.
Bit 14 = '1' means that the the torque limit in parameter
221 has been exceeded.
Bit 15, Thermal warning:
Bit 15 = '0' means that there is no thermal warning.
Bit 15 = '1' means that the temperature limit has been
exceeded either in the motor, in the frequency con-
verter, or from a thermistor connected to an analog
input.
Control word according to Fieldbus Profile
To select
Profidrive
in the control word, parameter 512
Telegram Profile
must be set to
Profidrive
[0].
The control word is used to send commands from a
master (e.g. a PC) to a slave (frequency converter).

Bit 00-01-02, OFF1-2-3/ON1-2-3:
Bit 00-01-02 = '0' causes ramp stop, which uses the
ramp time in parameters 207/208 or 209/210.
If
Relay 123
is selected in parameter 323
Relay out-
put
, the output relay will be activated when the output
frequency is 0 Hz.
Bit 00-01-02 = '1' means that the frequency converter
can start the motor if the other starting conditions are
fulfilled.
