Danfoss VLT 5000 Series, Instruction Manual, Page: 122 / 240

Runs on reference, no warning , speed according to ref-
erence. No warning.
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 pa-
rameter 223.
Under I high , the motor current is lower than set in pa-
rameter 224.
Out of frequency range
, the output frequency is outside
the frequency range programmed in parameters 225
and 226.
Over f low , the output frequency is higher than the val-
ue set in parameter 225.
Under f high , the output frequency is lower than the
value set in parameter 226.
Out of feedback range
, the feedback signal is outside
the range programmed in parameters 227 and 228.
Over feedback low , the feedback signal is higher than
the value set in parameter 227.
Under feedback high , the feedback signal is lower that
the value set in parameter 228.
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 card receives supply voltage
and there are no control signals on the inputs. No over-
temperature.
Ready - remote control - no thermal warning , the fre-
quency converter is ready for use and set at remote
control, the control card receives supply voltage. No
over-temperature.
Ready - mains voltage within range , the frequency con-
verter is ready for use, the control card receives supply
voltage and there are no control signals on the inputs.
The mains voltage is within the permitted voltage
range (see chapter 8).
Reversing. Logic '1' = relay activated, 24 V DC on the
output when the direction of rotation of the motor is
clockwise. Logic '0' = relay not activated, no signal on
the output, when the direction of rotation of the motor
is anti-clockwise.
Bus-ok , active communication (no time-out) via the se-
rial communication port.
Torque limit and stop is used in connection with coast-
ing stop (terminal 27), where it is possible to give a stop
even if the frequency converter is at the torque limit.
The signal is inverted, i.e. a logic `0' when the frequen-
cy 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 pro-
tect the frequency converter if there is a fault on the
brake modules. To avoid a potential fire in the brake
resistor, the output/relay can be used to cut out the
supply 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 exter-
nal mechanical brake, see also section Mechanical
brake control .
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 func-
tion is active, relays 01 and 04 will be voltage-free.
See section on Serial communication in the Design
Guide.
Extended mechanical brake control , enables control of
an external mechanical brake, see also section Me-
chanical brake control
.
Safety interlock The output is active when Safety inter-
lock has been selected on an input and the input is a
logic “1”.
