Table 7.35 Status Word According to FC Profile
Explanation of the status bits
Bit 00, Control not ready/ready
Bit 00=’0’: The frequency converter trips.
Bit 00=’1’: The frequency converter controls are ready but
the power component does not necessarily receive any
power supply (in case of external 24 V supply to controls).
Bit 01, Drive ready
Bit 01=’0’: The frequency converter is not ready.
Bit 01=’1’: The frequency converter is ready for operation
but the coasting command is active via the digital inputs
or via serial communication.
Bit 02, Coasting stop
Bit 02=’0’: The frequency converter releases the motor.
Bit 02=’1’: The frequency converter starts the motor with a
start command.
Bit 03, No error/trip
Bit 03=’0’ : The frequency converter is not in fault mode.
Bit 03=’1’: The frequency converter trips. To re-establish
operation, press [Reset].
Bit 04, No error/error (no trip)
Bit 04=’0’: The frequency converter is not in fault mode. Bit
04=“1”: The frequency converter shows an error but does
not trip.
Bit 05, Not used
Bit 05 is not used in the status word.
Bit 06, No error / triplock
Bit 06=’0’: The frequency converter is not in fault mode. Bit
06=“1”: The frequency converter is tripped and locked.
Bit 07, No warning/warning
Bit 07=’0’: There are no warnings.
Bit 07=’1’: A warning has occurred.
Bit 08, Speed≠ reference/speed=reference
Bit 08=’0’: The motor is running but the present speed is
different from the preset speed reference. It might for
example, be the case when the speed ramps up/down
during start/stop.
Bit 08=’1’: The motor speed matches the preset speed
reference.
Bit 09, Local operation/bus control
Bit 09=’0’: [Off/Reset] is activate on the control unit or
Local control in 3-13 Reference Site is selected. It is not
possible to control the frequency converter via serial
communication.
Bit 09=’1’ It is possible to control the frequency converter
via the fieldbus/serial communication.
Bit 10, Out of frequency limit
Bit 10=’0’: The output frequency has reached the value in
4-12 Motor Speed Low Limit [Hz] or 4-14 Motor Speed High
Limit [Hz].
Bit 10="1": The output frequency is within the defined
limits.
Bit 11, No operation/in operation
Bit 11=’0’: The motor is not running.
Bit 11=’1’: The coasting has a start signal or the output
frequency is greater than 0 Hz.
Bit 12, Drive OK/stopped, autostart
Bit 12='0’: There is no temporary over temperature on the
inverter.
Bit 12=’1’: The inverter stops because of over temperature
but the unit does not trip and resumes operation once the
over temperature stops.
Bit 13, Voltage OK/limit exceeded
Bit 13=’0’: There are no voltage warnings.
Bit 13=’1’: The DC voltage in the frequency converter’s
intermediate circuit is too low or too high.
Bit 14, Torque OK/limit exceeded
Bit 14=’0’: The motor current is lower than the torque limit
selected in 4-18 Current Limit.
Bit 14=’1’: The torque limit in 4-18 Current Limit is
exceeded.
