No operation
All digital and relay outputs are by
default set to
No Operation
.
[1]
Control Ready
The control card is ready, for example:
Feedback from a frequency converter
where the control is supplied by an
external 24 V supply (VLT
®
24 V DC
Supply MCB 107) and the main power
to frequency converter is not detected.
[2]
Drive ready
The frequency converter is ready to
operate. Mains and control supplies are
OK.
[3]
Drive rdy/rem ctrl The frequency converter is ready for
operation and is in
auto-on
mode.
[4]
Enable / no
warning
Ready for operation. No start or stop
commands have been applied (start/
disable). No warnings are active.
[5]
Running
The motor is running, and shaft torque
is present.
[6]
Running / no
warning
Output speed is higher than the speed
set in
parameter 1-81 Min Speed for
Function at Stop [RPM]
. The motor runs
and there are no warnings.
[7]
Run in range/no
warn
The motor runs within the
programmed current and the speed
ranges set in
parameter 4-50 Warning
Current Low
and
parameter 4-53 Warning Speed High
. No
warnings.
[8]
Run on ref/no
warn
The motor runs at reference speed. No
warnings.
[9]
Alarm
An alarm activates the output. No
warnings.
[10]
Alarm or warning
An alarm or a warning activates the
output.
[11]
At torque limit
The torque limit set in
parameter 4-16 Torque Limit Motor
Mode
or
parameter 4-17 Torque Limit
Generator Mode
has been exceeded.
[12]
Out of current
range
The motor current is outside the range
set in
parameter 4-18 Current Limit
.
[13]
Below current,
low
The motor current is lower than set in
parameter 4-50 Warning Current Low
.

Above current,
high
The motor current is higher than set in
parameter 4-51 Warning Current High
.
[15]
Out of speed
range
Output speed/frequency is outside the
frequency range set in
parameter 4-52 Warning Speed Low
and
parameter 4-53 Warning Speed High
.
[16]
Below speed, low
Output speed is lower than the setting
in
parameter 4-52 Warning Speed Low
.
[17]
Above speed,
high
Output speed is higher than the
setting in
parameter 4-53 Warning
Speed High
.
[18]
Out of feedb.
range
Feedback is outside the range set in
parameter 4-56 Warning Feedback Low
and
parameter 4-57 Warning Feedback
High
.
[19]
Below feedback,
low
Feedback is below the limit set in
parameter 4-56 Warning Feedback Low
.
[20]
Above feedback,
high
Feedback is above the limit set in
parameter 4-57 Warning Feedback High
.
[21]
Thermal warning
Thermal warning turns on when the
temperature exceeds the limit either in
motor, frequency converter, brake
resistor, or connected thermistor.
[22]
Ready,no thermal
W
The frequency converter is ready for
operation and there is no overtem-
perature warning.
[23]
Remote,ready,no
TW
The frequency converter is ready for
operation and is in
auto-on
mode.
There is no overtemperature warning.
[24]
Ready, Voltage OK The frequency converter is ready for
operation and the mains voltage is
within the specified voltage range (see
the
General Specifications
section in the
design guide
).
[25]
Reverse
The motor runs (or is ready to run)
clockwise when logic = 0 and counter-
clockwise when logic = 1. The output
changes as soon as the reversing
signal is applied.
[26]
Bus OK
Active communication (no timeout) via
the serial communication port.
[27]
Torque limit &
stop
Use for performing a coasted stop in a
torque limit condition. If the frequency
converter has received a stop signal
and is in torque limit, the signal is
logic 0.
[28]
Brake, no brake
war
Brake is active and there are no
warnings.
