Pulse Max 33/29
corresponds to parameter 205
Maximum reference Ref

.
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

308
308 Terminal 53, analogue input voltage
(AI [V]53FUNCT.)
Value:
No function (NO OPERA TION)
[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.

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.

Function:
This parameter is used for setting the signal value

Description of choice:
Set the required voltage value. For reasons of accu-

Value:
✭
No function (NO OPERA TION)
[0]
Reference (REFERENCE)

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.
