B track connected to terminal 33.
308
Terminal 53, analogue input voltage
Value:
No function (NO OPERATION)
[0]
Reference (reference)
[1]
Feedback (feedback)
[2]
Wobble (WOBB.DELTA FREQ [%])
[10]
Function:
In this parameter it is possible to select the function required to be con-
nected to terminal 53. Scaling of the input signal is made in parameter
309
Terminal 53, min. scaling
and parameter 310
Terminal 53, max.
scaling
.
Description of choice:
No function
[0]. Is selected if the frequency converter is not to react to
signals connected to the terminal.
Reference
[1]. If this function is se-
lected, the reference can be changed by means of an analogue reference
signal. If reference signals are connected to more than one input, these
reference signals must be added up.If a voltage feedback signal is con-
nected, select
Feedback
[2] on terminal 53.
Wobble
[10]
The delta frequency can be controlled by the analog input. If
WOBB.DEL-
TA FREQ
is selected as analog input (par. 308 or par. 314) the value
selected in par. 702 equals 100 % analog input.
Example: Analog input = 4-20 mA, Delta freq. par. 702 = 5 Hz
→
4 mA
= 0 Hz and 20 mA = 5 Hz. If this function is chosen, see Wobble Instruc-
tion MI28JXYY for further information.
309
Terminal 53 Min. scaling
Value:
0.0 - 10.0 Volt
0.0 Volt
Function:
This parameter is used for setting the signal value that is to correspond
to the minimum reference or the minimum feedback, parameter 204
Minimum reference, Ref
MIN
/ 414
Minimum feedback, FB
MIN
.
Description of choice:
Set the required voltage value. For reasons of accuracy, compensation
should be made for voltage loss in long signal cables. If the Time out
function is to be used (parameter 317
Time out
and 318
Function after
time out
), the value set must be higher than 1 Volt.
310
Terminal 53 Max. scaling
Value:
0 - 10.0 Volt
10.0 Volt
Function:
This parameter is used for setting the signal value that is to correspond
to the maximum reference value or maximum feedback, parameter 205
Maximum reference, Ref
MAX
/ 414
Maximum feedback, FB
MAX
.
Description of choice:
Set the required voltage value. For reasons of accuracy, compensation
should be made for voltage losses in long signal cables.
314
Terminal 60, analogue input current
Value:
No function (no operation)
[0]
Reference (reference)
[1]
Feedback (feedback)
[2]
Wobble (WOBB.DELTA FREQ [%])
[10]
Function:
This parameter allows a choice between the different functions available
for the input, terminal 60. Scaling of the input signal is effected in pa-
rameter 315
Terminal 60, min. scaling
and parameter 316
Terminal 60,
max. scaling
.
Description of choice:
No function
[0]. Is selected if the frequency converter is not to react to
signals connected to the terminal.
Reference
[1]. If this function is se-
lected, the reference can be changed by means of an analogue reference
signal. If reference signals are connected to more than one input, these
reference signals must be added up.
If one current feedback signal is connected, select
Feedback
[2] on ter-
minal 60.
Wobble
[10]
The delta frequency can be controlled by the analog input. If
WOBB.DEL-
TA FREQ
is selected as analog input (par. 308 or par. 314) the value
selected in par. 702 equals 100 % analog input.
Example: Analog input = 4-20 mA, Delta freq. par. 702 = 5 Hz
→
4 mA
= 0 Hz and 20 mA = 5 Hz. If this function is chosen, see Wobble Instruc-
tion MI28JXYY for further information.
315
Terminal 60 Min. scaling
Value:
0.0 - 20.0 mA
4.0 mA
Function:
In this parameter you can set the signal value that will correspond to the
minimum reference or minimum feedback, parameter 204
Minimum ref-
erence, Ref
MIN
/ 414
Minimum feedback, FB
MIN
.
Description of choice:
Set the required current value. If the Time out function is to be used
(parameter 317
Time out
and 318
Function after time out
) the value set
must be higher than 2 mA.
316
Terminal 60 Max. scaling
Value:
0.0 - 20.0 mA
20.0 mA
Function:
This parameter is used for setting the signal value that is to correspond
to the maximum reference value, parameter 205
Maximum reference
value, Ref
MAX
.
Description of choice:
Set the required current value.
317
Time out
Value:
1 - 99 sec.
10 sec.
Function:
If the signal value of the reference or feedback signal connected to one
of the input terminals 53 or 60 falls below 50 % of the minimum scaling
for a period longer than the time set, the function selected in parameter
318
Function after time out
will be activated. This function is only active
if in parameter 309
Terminal 53, min. scaling
a value higher than 1 Volt
has been selected, or if in parameter 315
Terminal 60, min. scaling
a
value higher than 2 mA has been selected.
