VLT
®
5000 Series
Function:
This output can act both as a digital and an ana-
logue output. If used as a digital output (data value
[0]-[65]), a 24 V DC signal is transmitted; if used as
an analogue output either a 0-20 mA signal, a 4-20
mA signal or a pulse output is transmitted.
Description of choice:
Control ready , the VLT frequency converter is ready
for use; the control card receives supply voltage.
Ready signal , the VLT frequency converter control
card is receiving a supply signal and the frequency
converter is ready for operation.
Ready, remote control , the VLT frequency converter
control card is receiving a supply signal and parame-
ter 002 has been set to remote control.
Enable, no warning , the VLT frequency converter is
ready for use; no start or stop command has been
given (start/disable). No warning.
Running , a start command has been given.
Running, no warning , the output frequency is higher
than the frequency set in parameter 123. A start
command has been given. No warning.
Runs in range, no warning , runs within the
programmed current/frequency ranges set in param-
eters 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 out-
side 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 out-
side 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 ei-
ther the motor, the VLT frequency converter, the
brake resistor or the thermistor.
Ready - no thermal warning , the VLT 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
VLT frequency converter is ready for use and set at
remote control, the control card receives supply volt-
age. No over-temperature.
Ready - mains voltage within range , the VLT fre-
quency converter is ready for use, the control card
receives supply voltage and there are no control sig-
nals 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 sig-
nal 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 VLT frequency converter is at
the torque limit. The signal is inverted, i.e. a logic ‘0’
when the VLT 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 opera-
tion 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 VLT frequency converter if there is a
