VLT® 7000 Booster
Programming
Function:
This output can act both as a digital or an analogue
output. If used as a digital output (data value [0]-[59]), a
0/24 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 sequence of 0-32000 pulses is transmitted.
Description of choice:
No function. Selected if the frequency converter
is not to react to signals.
Drive ready. The frequency converter control
card receives a supply voltage and the frequency
con-verter is ready for operation.
Stand by. The frequency converter 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 frequency converter 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 I
LIM
.
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 anti-clockwise. When the motor
rotates clockwise, the value is 0 V DC.
Thermal warning. The temperature limit in either
the motor, the frequency converter or a thermistor
connected to an analogue input has been exceeded.
Hand mode active. The output is active when the
frequency converter is in Hand mode.
Auto mode active. The output is active when the
frequency converter is in Auto mode.
Sleep mode . Active when the frequency
conver-ter is in Sleep mode.

Relay 123 . This function is only used when a
profibus option card is installed.
Mains imbalance . This output is activated at
too high mains imbalance or when a phase is
missing in the mains supply. Check the mains
voltage to the frequency converter.
