Danfoss VLT 5000 FLUX Operating Instructions Manual page 97

Runs on reference, no warning, speed
according to reference.
Fault, output is activated by alarm.
Fault or warning, the output is activated by
alarm or warning.
Torque limit, the torque limit in parameter
221 has been exceeded.
Out of current range, the motor current is outside the
range programmed in parameters 223 and 224.
Over I low, the motor current is higher than
set in parameter 223.
Under I high, the motor current is lower than
set in parameter 224.
Out of range speed, the output speed is outside the
speed range programmed in parameters 225 and 226.
Over n low, the output speed is higher than the
value set in parameter 225.
Under n high, the output speed is lower than
the value set in parameter 226.
Thermal warning, above the temperature limit
in either the motor, the frequency converter, the
brake resistor or the thermistor.
Ready - no thermal warning, the frequency converter
is ready for use, the control board receives supply
voltage and there are no control signals on the
inputs. No over-temperature.
Ready - remote control - no thermal warning , the
frequency converter is ready for use and set at
remote control, the control board receives supply
voltage. No over-temperature.
Ready - mains voltage within range, the frequency
converter is ready for use, the control board receives
supply voltage and there are no control signals on
the inputs. The mains voltage is within the permitted
voltage range (see section Technical Data).
Reversing. Logic '1' = relay activated, 24 V DC on
the output when CW rotation of the motor. Logic
'0' = relay not activated, no signal on the output,
when the CCW rotation of the motor.
Bus-ok, active communication (no time-out) via
the serial communication port.
Torque limit and stop is used in connection with
coasting stop (terminal 27), also in torque limit condition.
= factory setting. () = display text [] = value for use in communication via serial communication port

The signal is logic '0' when frequency converter has
received a stop signal and is at the torque limit.
Brake, no brake warning, the brake is active
and there are no warnings.
Brake ready, no fault, the brake is ready for
operation and there are no faults.
Brake fault, the output is a logical "1" when the brake
IGBT has short-circuited. This function is used to
protect the frequency converter if there is a fault on the
brake modules. The output/relay can be used to cut
out the main voltage from the frequency converter.
Relay 123, if Fieldbus profile [0] has been selected in
parameter 512, the relay is activated. If either OFF1,
OFF2 or OFF3 (bit in the control word) is logic '1'.
Mechanical brake control, enables control of an
external mechanical brake, see description in the
section Control of Mechanical Brake.
Control word bits 11/12, relay controlled via bits 11/12
in serial control word. Bit 11 relates to relay 01 and
bit 12 to relay 04. If parameter 514 Bus time interval
function is active, relays 01 and 04 will be open state.
See section on Serial communication in the
Design Guide.
