RS-485 Installation and Set...
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
different from the preset speed reference. For example,
this might 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
12 12
frequency drive via the serial communication / bus
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 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.

Design Guide
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.
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%.
All bits in the STW are set to '0' if the connection between
the Interbus option and the adjustable frequency drive is
lost, or if an internal communication problem has occurred.
12.13.3 Bus Speed Reference Value
Speed reference value is transmitted to the adjustable
frequency drive in a relative value expressed as %. The
value is transmitted in the form of a 16-bit word; in
integers (0–32767) the value 16384 (4000 hex) corresponds
to 100%. Negative figures are formatted by means of 2's
complement. The actual output frequency (MAV) is scaled
in the same way as the bus reference.
