Table 3.46 Status Word Bits
Explanation of the status bits
Bit 00, Control not ready/ready
Bit 00=0: The adjustable frequency drive trips.
Bit 00=1: The adjustable frequency drive 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=1: The adjustable frequency drive 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 adjustable frequency drive releases the
motor.
Bit 02=1: The adjustable frequency drive starts the motor
with a start command.
Bit 03, No error/trip
Bit 03=0: The adjustable frequency drive is not in fault
mode.
Bit 03=1: The adjustable frequency drive trips. To re-
establish operation, enter [Reset].
Bit 04, No error/error (no trip)
Bit 04=0: The adjustable frequency drive is not in fault
mode.
Bit 04=1: The adjustable frequency drive 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 adjustable frequency drive is not in fault
mode.
Bit 06=1: The adjustable frequency drive 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
dierent 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: [Stop/Reset] is activated on the control unit or
Local control in 3-13 Reference Site is selected. Control via
serial communication is not possible.
Bit 09=1 It is possible to control the adjustable frequency
drive via the serial communication bus/serial communi-
cation.
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
dened limits.
Bit 11, No operation/in operation
Bit 11=0: The motor is not running.
Bit 11=1: The adjustable frequency drive 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 overtemperature on the
inverter.
Bit 12=1: The inverter stops because of overtemperature,
but the unit does not trip and resumes operation once the
overtemperature stops.
Bit 13, Voltage OK/limit exceeded
Bit 13=0: There are no voltage warnings.
Bit 13=1: The DC voltage in the adjustable frequency
drive’s intermediate circuit is too low or too high.
