Table 7.39 Status Word According to FC Prole
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
supply (if there is 24 V external supply to controls).
Bit 01, Frequency converter 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, Coast 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 runs, but the present speed is
dierent from the preset speed reference. It might happen
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: [O/Reset] is activated on the control unit or [2]
Local in parameter 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 eldbus/serial communication.
Bit 10, Out of frequency limit
Bit 10 = 0: The output frequency has reached the value in
parameter 4-12 Motor Speed Low Limit [Hz] or
parameter 4-14 Motor Speed High Limit [Hz].
Bit 10 = 1: The output frequency is within the dened
limits.
Bit 11, No operation/in operation
Bit 11 = 0: The motor is not running.
Bit 11 = 1: The frequency converter has a start signal
without coast.
Bit 12, Frequency converter OK/stopped, auto start
Bit 12 = 0: There is no temporary overtemperature on the
frequency converter.
Bit 12 = 1: The frequency converter stops because of
overtemperature but the unit does not trip and resumes
operation once the overtemperature normalizes.
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 DC
link is too low or too high.
