6 How to control the Frequency Converter
6.2.4 Explanation of the Status Bits
Bit 00, Control not ready / ready:
Bit 00 set to [0] means that the frequency converter has tripped.
Bit 00 set to [1] means that the frequency converter controls are ready,
but that the power component is not necessarily receiving any power
supply (in the event of external 24 V supply to controls).
Bit 01, Drive ready:
Bit 01 set to [1] means that the frequency converter is ready for opera-
tion, but it is receiving an active coasting command via the digital inputs
or via serial communication.
Bit 02, Coasting stop:
Bit 02 set to [0] means that the frequency converter has released the
motor.
Bit 02 set to [1] means that the frequency converter can start the motor
6
when a start command is given.
Bit 03, No error / trip:
Bit 03 set to [0] means that the frequency converter is not in fault mode.
Bit 03set to [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 set to [0] means that the frequency converter is not in fault mode.
Bit 04 set to [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 / trip lock:
Bit 06 set to [0] means that the frequency converter is not in fault mode.
Bit 06 set to [1] means that the frequency converter is tripped and locked.
Bit 07, No warning / warning:
Bit 07 set to [0] means that there are no warnings.
Bit 07 set to [1] means that a warning has occurred.
Bit 08, Speed # reference / speed = reference:
Bit 08 set to [0] means that the motor is running, but that the present
speed is different from the preset speed reference. For example, this
might occur while the speed is being ramped up/down during start/stop.
Bit 08 set to [1] means that the present motor speed matches the preset
speed reference.
Bit 09, Local operation / bus control:
Bit 09 set to [0] means that [STOP/RESET] is activated on the control unit
or that Local [2] control in par. 3-13
possible to control the frequency converter via serial communication.
Bit 09 set to [1] means that it is possible to control the frequency con-
verter via the fieldbus / serial communication interface.
Bit 10, Out of frequency limit:
Bit 10 set to [0] enables the output frequency to reach the value in
par. 4-11 Motor Speed Low Limit [RPM]
Limit [RPM]
.
Bit 10 set to [1] means that the output frequency is within the defined
limits.
Bit 11, No operation / in operation:
Bit 11 set to [0] means that the motor is not running.

Reference Site
is selected. It is not
or par. 4-13 Motor Speed High
MG.11.E2.02 - VLT
Bit 11 set to [1] means that the frequency converter has received a start
signal or that the output frequency is greater than 0 Hz.
Bit 12, Brake OK / Brake warning or failure:
Bit 12 = [0] means that there is no brake warning or failure present.
Bit 12 = [1] means that the drive has stopped because of a brake warning
or failure.
Bit 13, Voltage OK / limit exceeded:
Bit 13 set to [0] means that there are no voltage warnings.
Bit 13 set to [1] means that the DC voltage in the frequency converter's
intermediate circuit is too low or too high.
Bit 14, Torque OK / limit exceeded:
Bit 14 set to [0] means that the motor current is lower than the torque
limit selected in par. 4-18 Current Limit
Bit 14 set to [1] means that the torque limit in par. 4-18
has been exceeded.
Bit 15, Timer OK / limit exceeded:
Bit 15 = [0] means that the timers for motor thermal protection and VLT
thermal protection, respectively, have not exceeded 100%.
Bit 15 = [1] means that one of the timers has exceeded 100%.
