Control
Explanation of the status bits
Bit 00, Control not ready/ready:
Bit 00 = 0 means that the frequency converter has tripped.
Bit 00 = 1 means that the frequency converter controls are
ready, but that the power component is not necessarily
receiving any power supply (in case of 24 V external
supply to controls).
Bit 01, Frequency converter ready:
4 4
Bit 01 = 1. The frequency converter is ready for operation,
but there is an active coasting command via the digital
inputs or via serial communication.
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 means that the frequency converter is not in
fault mode.
Bit 03 = 1 means that the frequency converter is tripped,
and that a reset signal is required to re-establish operation.
Bit 04, No error/error (no trip):
Bit 04 = 0 means that the frequency converter is not in
fault mode.
Bit 04 = 1 means that there is a frequency converter error
but no trip.
Bit 05, Not used:
Bit 05 is not used in the status word.
Bit 06, No error/triplock:
Bit 06 = 0 means that the frequency converter is not in
fault mode.
Bit 06 = 1 means that the frequency converter is tripped,
and locked.
Bit 07, No warning/warning:
Bit 07 = 0 means that there are no warnings.
Bit 07 = 1 means that a warning has occurred.
Bit 08, Speed ≠ reference/speed = reference:
Bit 08 = 0 means that the motor is running, but that the
present speed is different from the preset speed reference.
It might, for example, be the case while the speed is being
ramped up/down during start/stop.
Bit 08 = 1 means that the present motor present speed
matches the preset speed reference.
Bit 09, Local operation/bus control:
Bit 09 = 0 means that [STOP/RESET] is pressed on the
control unit, or that local control in
parameter 3-13 Reference Site is selected. It is not possible
to control the frequency converter via serial communi-
cation.
Bit 09 = 1 means that it is possible to control the
frequency converter via the fieldbus/ serial communication.

Bit 10, Out of frequency limit:
Bit 10 = 0 if 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 means that the output frequency is within the
defined limits.
Bit 11, No operation/in operation:
Bit 11 = 0 means that the motor is not running.
Bit 11 = 1 means that the frequency converter has a start
signal or that the output frequency is greater than 0 Hz.
Bit 12, Frequency converter OK/stopped, auto start:
Bit 12 = 0 means that there is no temporary overtem-
perature on the inverter.
Bit 12 = 1 means that the inverter has stopped because of
overtemperature, but that the unit has not tripped and will
resume operation once the overtemperature stops.
Bit 13, Voltage OK/limit exceeded:
Bit 13 = 0 means that there are no voltage warnings.
Bit 13 = 1 means that the DC voltage in the frequency
converter's DC link is too low or too high.
Bit 14, Torque OK/limit exceeded:
Bit 14 = 0 means that the motor current is lower than the
torque limit selected in parameter 4-18 Current Limit.
Bit 14 = 1 means that the torque limit in
parameter 4-18 Current Limit has been exceeded.
Bit 15, Timer OK/limit exceeded:
Bit 15 = 0 means that the timers for motor thermal
protection and frequency converter thermal protection,
respectively, have not exceeded 100%.
Bit 15 = 1 means that 1 of the timers has exceeded 100%.
