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 24V supply to controls).
Bit 01, Drive 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, enter [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 e.g. 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’: [STOP/RESET] is activate on the control unit or
Local control in 3-13 Reference Site is selected. You cannot
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
4-11 Motor Speed Low Limit [RPM] or 4-13 Motor Speed High
Limit [RPM]. 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
frequency converter 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 will resume
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:
