Control word bit 11
(CTRL W. BIT 11)
[26]
Function:
The relay output can be used for giving the present
status or warning. The output is activated (1–2
make) when a given condition is fulfilled.
Description of choice:
No function
. Is selected if the frequency converter
is not to react to signals.
Unit ready
, there is a supply voltage on the control
card of the frequency converter, and the frequency
converter is ready for operation.
Enable, no warning
, the frequency converter
is ready for operation, but no start command
has been given. No warning.
Running
, a start command has been given.
Running in reference, no warning
speed
according to reference.
Running, no warning
, a start command has
been given. No warning.
Ready - mains voltage within range
, the frequency
converter is ready for use; the control card is
receiving a supply voltage; and there are no
active control signals on the inputs. The mains
voltage lies within the voltage limits.
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
frequency is higher than the value set in parameter
225
Warning: Low frequency, f
LOW
.
Output frequency lower than f
HIGH
,
the output
frequency is lower than the value set in parameter
226
Warning: 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
LOW
.
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 direction of motor rotation is anti-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 frequency converter, 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 Design Guide).
Control word bit 11,
bit 11of the control word, the
relay output will be set/reset according to bit 11.
