Explanation of the Status Bits
Bit 00, Control ready:
Bit 00 = '0' means that the frequency converter has tripped. Bit 00 = '1' means
that the frequency converter controls are ready, but that the power compo-
nent is not necessarily receiving any power supply (in the event of external
24 V supply to controls).
Bit 01, Drive ready:
Bit 01 = '1'. The frequency converter is ready for operation.
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 error/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 a reset signal is
required to re-establish operation.
Bit 04, No error/Error (no trip):
Bit 04 = '0' means that the frequency converter is not in fault mode. Bit 04 =
'1' means that there is a frequency converter error but no trip.
Bit 05, Reserved:
Bit 05 is not used in the status word.
Bit 06, No error / Trip lock:
Bit 06 = '0' means that the frequency converter is not in fault mode. Bit 06 =
'1' means that the frequency converter is tripped, and locked.

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≠ reference/Speed = reference:
Bit 08 = '0' means that the motor is running, but that the present speed is
different from the preset speed reference. For example, this might occur while
the speed is being acceled/deceled during start/stop. Bit 08 = '1' means that
the present motor speed matches the preset speed reference.
Bit 09, Local operation/Bus control:
Bit 09 = '0' means that [STOP/RESET] is activated on the control unit, or that
Local control in par. F-02 Operation Method 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 the network/ serial
communication.
Bit 10, Out of frequency limit:
Bit 10 = '0', if the output frequency has reached the value in par. F-18 Motor
Speed Low Limit [RPM] or par. F-17 Motor Speed High Limit [RPM]. Bit 10 = '1'
means that the output frequency is within the defined limits.
Bit 11, No operation/In operation:
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, Drive OK/Stopped, auto start:
Bit 12 = '0' means that there is no temporary over temperature on the inverter.
Bit 12 = '1' means that the inverter has stopped because of over temperature,
but that the unit has not tripped and will resume operation once the over
temperature stops.
Bit 13, Voltage OK/Voltage exceeded:
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/Torque limit exceeded:
Bit 14 = '0' means that the motor current is lower than the torque limit selected
in par. F-40 and F-41 Torque limit. Bit 14 = '1' means that the torque limit in
par. F-40 and F-41 Torque limit has been exceeded. The nominal torque can
be read in par. DR-16 Torque [Nm].
Bit 15, Thermal OK/limit exceeded:
Bit 15 = '0' means that the timers for both motor thermal protection and drive
thermal protection, have not exceeded 100%. Bit 15 = '1' means that one of
the limits has exceeded 100%.
