Danfoss VLT FCD 311 Design Guide

VLT

FCD Series
Pulse Max 33/29 corresponds to parameter 205
Maximum reference Ref
MAX
.
Encoder feedback is selected if the feedback signal
used is a pulse train (frequency). In parameter 327/
328 Pulse Max 33/29 the maximum pulse feedback
frequency is set.
Encoder input is selected if a specific number of
pulses must lead to a Precise stop, see parameter
343 Precise stop and parameter 344 Counter value.
308
308 Terminal 53, analogue input voltage
(AI [V]53FUNCT.)
Value:
No function (NO OPERATION)
[0]
✭Reference (REFERENCE)
[1]
Feedback (FEEDBACK)
[2]
Function:
In this parameter it is possible to select the function
required to be connected 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 selected, the refer-
ence 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 connected, select
Feedback [2] on terminal 53.
309
309 Terminal 53 Min. scaling
(AI 53 SCALE LOW)
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 ref-
erence, Ref
MIN
/ 414 Minimum feedback, FB
MIN
Description of choice:
Set the required voltage value. For reasons of accu-
racy, compensation should be made for voltage
losses 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
310 Terminal 53 Max. scaling
(AI 53 SCALE HIGH)
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 ref-
erence, Ref
MAX
/ 414 Maximum feedback, FB
MAX
.
Description of choice:
Set the required voltage value. For reasons of accu-
racy, compensation should be made for voltage
losses in long signal cables.
314
314 Terminal 60, analogue input current
(AI [MA] 60 FUNCT)
Value:
✭No function (NO OPERATION)
[0]
Reference (REFERENCE)
[1]
Feedback (FEEDBACK)
[2]
Function:
This parameter allows a choice between the different
functions available for the input, terminal 60. Scaling
of the input signal is effected in parameter 315 Ter-
minal 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 selected, the refer-
ence 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.
