4000 VT
Programming
Function:
This output can act both as a digital or an analog
output. If used as a digital output (data value [0]-[59]), a
0/24 V DC signal is transmitted; if used as an ana-loge
output, either a 0-20 mA signal, a 4-20 mA sig-nal or a
pulse sequence of 0-32000 pulses is transmitted.
Description of choice:
No function.
Selected if the VLT AFD is
not to react to signals.
Drive ready.
The VLT AFD control card receives a
supply voltage and the AFD is ready for operation.
Stand by.
The VLT AFD is ready for operation, but no
start command has been given. No warning.
Running.
A start command has been given.
Running at ref. value.
Speed according to reference.
Running, no warning.
A start command has
been given. No warning.
Local reference active.
The output is active
when the motor is controlled by means of the
local reference via the control unit.
Remote references active.
The output is
active when the VLT AFD is controlled by means
of the remote references.
Alarm.
The output is activated by an alarm.
Alarm or warning.
The output is activated
by an alarm or a warning.
No alarm.
The output is active when there is no alarm.
Current limit.
The output current is greater than the
value programmed in parameter 215 Current limit ILIM.
Safety interlock.
The output is active when
terminal 27 is a logic ‘1
’
and Safety interlock
has been selected on the input.
Start command active.
Is active when there is a start
command or the output frequency is above 0.1 Hz.
Reversing.
There is 24 V DC on the output when the
motor rotates counter-clockwise. When the mo-tor
rotates clockwise, the value is 0 V DC.
Thermal warning.
The temperature limit in either
the motor, the VLT AFD or a thermistor connected
to an analogue input has been exceeded.
Hand mode active.
The output is active when
the VLT AFD is in Hand mode.
Auto mode active.
The output is active when
the VLT AFD is in Auto mode.
Sleep mode.
Active when the VLT AFD
is in Sleep mode.
