Bit 05, Not used:
Bit 05 is not used in the status w ord.
B
it 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 connected a gain.
B
it 07, No w arning/warning:
Bit 07 = ’0’ me ans that there are no warnings.
Bit 07 = ’1’ means that a warning has occurred.
Bit 08, Speed≠ ref/speed = ref.:
Bit 0 8 = ’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’spresentspeed
is the same as the preset speed reference.
B
it 09, Local operation/serial communica tion con trol:
Bit 0 9 = ’0’ means that [STOP/RESET] is act ivated on
the control unit, or that Local control in p arameter
002 Local/remote operation is selected. It is
not possible to control the frequency converter
via serial communication.
Bit 09 = ’1’ means that it is possible to control the
frequency converter via serial communication.
B
it 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" mea ns that the output
frequency is within the defined limits.
B
it 11, Runn ing/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.
B
it 13, Voltage warning high/low:
Bit 13 = ’0’ mea n s 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.
B
it 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 22 1 Current
LimitI
LIM
and that the frequency converter will
trip after a set period of time.
B
it 15, Th ermal warning:
Bit 15 = ’0’ means that there is no thermal warning.
Bit 15 = ’1’ means that the temperature limit has bee n
exceeded in either the m otor, frequency converter or
from a thermistor that is connected to a d igital 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). Master⇒Slave.

Bit 00-01-02, OFF1 -2-3/ON 1-2-3:
Bit 00-01-02 = ’0’ causes ramp stop, which uses the
ramp time in pa rame ters 207/208 or 209/210.
If Relay 123 is selected in parameter 323 Relay
output, 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.
B
it 03, Coasting stop:
See description under Control word according
to FC protocol.
