VLT
®
5000 Series
Runs in range, no warning, runs within the programmed
current/frequency ranges set in parameters 223-226.
Runs on reference, no warning, speed according
to reference. 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 parameter 223.
Under I high, the motor current is lower than
set in parameter 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 value 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
frequency 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
converter 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 serial communication port.
Torque limit and stop is used in connection with
coasting 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 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. 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 external 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
function 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 Mechanical brake control.
Safety interlock TheoutputisactivewhenSafety
interlock has been selected on an input and
the input is a logic "1".
