Table 4.8 Status Bits
Explanation of the status bits:
Bit 00, Control not ready/ready
Bit 00 = 0: The frequency converter has tripped.
Bit 00 = 1: The frequency converter controls are ready, but
the power component is not necessarily receiving any
power supply (if there is 24 V external supply to controls).
Bit 01, Drive ready
Bit 01 = 1: The frequency converter is ready for operation.
Bit 02, Coasting stop
Bit 02 = 0: The frequency converter has released the motor.
Bit 02 = 1: The frequency converter can start the motor
when a start command is given.
Bit 03, No error/trip
Bit 03 = 0: The frequency converter is not in fault mode.
Bit 03 = 1: The frequency converter is tripped, and a reset
signal is required to re-establish operation.
Bit 04, No error/error (no trip)
Bit 04 = 0: The frequency converter is not in fault mode.
Bit 04 = 1: There is a frequency converter error but no trip.
Bit 05, Not used
Bit 05: Not used in the status word.
Bit 06, No error/trip lock
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. For example, it
could be the case while the speed is being ramped up/
down during start/stop.
Bit 08 = 1: The present 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. It is
not possible to 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
parameter 4-52 Warning Speed Low
or
parameter 4-53 Warning Speed High
.
Bit 10 = 1: The output frequency is within the defined
limits.
Bit 11, No operation/in operation
Bit 11 = 0: The motor does not run.
Bit 11 = 1: The frequency converter has a start signal, or
the output frequency is greater than 0 Hz.
Bit 12, Drive OK/stopped, auto start
Bit 12 = 0: There is no temporary overtemperature on the
inverter.
Bit 12 = 1: The inverter has stopped because of overtem-
perature, but the unit has not tripped 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 frequency converters 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 4-16 Torque Limit Motor Mode
or
parameter 4-17 Torque Limit Generator Mode
.
Bit 14 = 1: The torque limits in
parameter 4-16 Torque Limit
Motor Mode
and
parameter 4-17 Torque Limit Generator
Mode
are exceeded.
Bit 15, Timer OK/limit exceeded
Bit 15 = 0: The timers for motor thermal protection and
frequency converter thermal protection, respectively, have
not exceeded 100%.
Bit 15 = 1: One of the timers has exceeded 100%.
