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. It could 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. The
adjustable frequency drive cannot be controlled via serial
communication.
Bit 09=’1’ It is possible to control the adjustable frequency
drive via the serial communication bus.
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 intermediate circuit 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 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%.
If the connection between the Interbus option and the
adjustable frequency drive is lost, or an internal communi-
cation problem has occurred, all bits in the STW are set
to ’0.'
