Danfoss VLT 2822 General Information

Alarm or warning: the output is activated by an alarm
or warning.
Current limit: the output current is higher than the value
programmed in parameter 221 Current limit I
LIM
.
Alarm: the output is activated by an alarm.
Output frequency higher than f
LOW
: the output frequen-
cy is higher than the value set in parameter 225
Warning: Low frequency, f
LOW
.
Output frequency lower than f
HIGH
: the output frequen-
cy is lower than the value set in parameter 226 Warn-
ing: High frequency, f
HIGH
.
Output current higher than I
LOW
: the output current is
higher than the value set in parameter 223 Warning:
Low current, I

.
Output current lower than I
HIGH
: the output current is
lower than the value set in parameter 224 Warning:
High current, I
HIGH
.
Feedback higher than FB
LOW
: the feedback value is
higher than the value set in parameter 227 Warning:
Low feedback, FB
LOW
.
Feedback lower than FB
HIGH
: the feedback value is
lower than the value set in parameter 228 Warning:
High current, I
HIGH
.
Relay 123 is only used in connection with Profidrive.
Reversing: the relay output is activated when the di-
rection of motor rotation is counter-clockwise. When
the direction of motor rotation is clockwise, the value
is 0 V DC.
Thermal warning: above the temperature limit in either
the motor or the adjustable frequency drive, or from a
thermistor connected to a digital input.
Local operation: the output is active when in parameter
002 Local/remote operation, Local operation [1] has
been selected.
Out of the frequency range: the output frequency is out
of the programmed frequency range in parameters
225 and 226.
Out of the current range: the motor current is out of the
programmed range in parameters 223 and 224.
Out of the feedback range: the feedback signal is out
of the programmed range in parameters 227 and 228.
Mechanical brake control: enables you to control an
external mechanical brake (see section about control
of mechanical brake in the VLT 2800 Design Guide).

.
Description of choice:
Set the required pulse reference or pulse feedback to
be connected to terminal 33.
328 Maximum Pulse 29
(MAX PULSE 29)
Value:
150 - 67600 Hz
5000 Hz
Function:
This parameter is used for setting the signal value that
corresponds to the maximum value set in parameter
205 Maximum reference, Ref
MAX
or to the maximum
feedback value set in parameter 415 Maximum feed-
back, FB
MAX
.
