Bit 06, Trip lock:
Bit 06 = '0' means that the frequency converter is not
trip locked.
Bit 06 = '1' means that the frequency converter is trip
locked and it cannot be reset before the mains supply
has been removed. The trip can be reset either with 24
V external control back up or after the power is con-
nected again.
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 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, Current limit:
Bit 14 = '0' means that the output current is less than
the value in parameter 221 Current Limit I
LIM
.
Bit 14 = '1' means that the output current is greater than
the value in parameter 221 Current LimitI
LIM
and that
the frequency converter will trip after a set period of
time.
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 in either the motor, frequency converter or
from a thermistor that is connected to a digital 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.
