10 Out of frequency limit Frequency limit OK
11 No operation In operation
12 Drive OK Stopped, auto start
13 Voltage OK Voltage exceeded
14 Torque OK Torque exceeded
15 Timer OK Timer exceeded
Bit 00, Control not ready/ready
Bit 00=0: The drive trips.
Bit 00=1: The drive controls are ready, but the power
component does not necessarily receive any supply in the
case of a 24 V external supply to the controls.
Bit 01, Drive ready
Bit 01=1: The 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 drive releases the motor.
Bit 02=1: The drive starts the motor with a start command.
Bit 03, No error/trip
Bit 03=0: The drive is not in fault mode.
Bit 03=1: The drive trips. To re-establish operation, press
[Reset].
Bit 04, No error/error (no trip)
Bit 04=0: The drive is not in fault mode.
Bit 04=1: The 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 drive is not in fault mode.
Bit 06=1: The 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. For example,
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 [2]
Local in parameter 3-13 Reference Site is selected. The drive
cannot be controlled via serial communication.
Bit 09=1 It is possible to control the drive via the eldbus/
serial communication.
Bit 10, Out of frequency limit
Bit 10=0: The output frequency has reached the value in
parameter 4-11 Motor Speed Low Limit [RPM] or
parameter 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 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 DC link 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 parameter 4-18 Current Limit.
Bit 14=1: The torque limit in parameter 4-18 Current Limit is
exceeded.
Bit 15, Timer OK/limit exceeded
Bit 15=0: The timers for motor thermal protection and
thermal protection are not exceeded 100%.
Bit 15=1: One of the timers exceeds 100%.
If the connection between the InterBus option and the
drive is lost, or an internal communication problem has
occurred, all bits in the STW are set to 0.
