Table 4.14 Status Word Bit Definition
Bit 00, Control ready
Bit 00='1'. The frequency converter is ready for operation.
Bit 00='0'. The frequency converter is not ready for
operation.
Bit 01, Drive ready
Bit 01='1'. The frequency converter is ready for operation,
but there is an active coasting command via the digital
inputs or via serial communication.
Bit 02, Coasting stop
Bit 02='0'. The frequency converter has released the motor.
Bit 02='1'. The frequency converter can start the motor
when a start command is given.
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 tripped,
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, 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 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
Bit=1
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
Trip
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 [1] Local control in parameter 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.
OK
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
Bit 14='1' means that the output current is greater than
the value in parameter 221 Current LimitI
frequency converter trips 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.
