Selection of Setup, lsb
and
Selection of Setup,
msb
gives the possibility to select one of the
four setups. It is, however, a condition that
parameter 004 is set to
Multisetup
.
Reset and start
can be used as a start function. If 24
V are connected to the digital input, this will cause
the variable frequency drive to reset and the motor
will ramp up to the preset reference.
Encoder reference
is selected if the reference
signal applied is a pulse train (frequency). 0 Hz
corresponds to parameter 204
Minimum reference,

MIN
. The frequency set in parameter 327/328
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

All encoder settings are used in connection with dual
track encoders with direction recognition.
A track connected to terminal 29.
B track connected to terminal 33.

Description of choice:
No function
[0]. Is selected if the variable frequency
drive is not to react to signals connected to the terminal.
Reference
[1]. If this function is selected, the reference
can be changed by means of an analog 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

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
