Max. limit (XXX.X)
[XXXX]
I
RATED
= rated motor current
Min. limit = magnetising current in% of I
RATED
Max. limit = unit dependent limit in% of I
RATED
Function:
This function is relevant for all application configurations;
speed and process regulation. This is where to set the
current limit for motor operation.

Illustration 3.20
Description of choice:
Set the desired % of current.
229
Frequency bypass, bandwidth
Value:
0 (OFF)-100%
[0-100]
0 (OFF)%
[0]
Function:
Some Systems call for some output frequencies to be
avoided because of resonance problems in the System.
In parameters 230-231 these output frequencies can be
programmed for bypassing (Frequency bypass). In this
parameter (229), a bandwidth can be defined on either
side of the frequency bypasses.
Description of choice:
The bypass band is the bypass fre/- half the set
bandwidth.
A percentage of the setting in parameters 230-231 is
selected.

Frequency bypass 1
231
Frequency bypass 2
Value:
0.0-132 Hz (parameter 200)
[0 -]
0.0 Hz
[0]
Function:
Some Systems call for some output frequencies to be
avoided because of resonance problems in the System.
Description of choice:
Enter the frequencies to be avoided.

% of the reference range/external reference
0.00%
[0]
Function:
Seven different reference presets can be programmed in
parameters 241 - 247
reference prese
t. The reference preset
is stated as a percentage of the value Ref
MAX
or as a
percentage of the other external references, depending on
the choice made in parameter 214. If a Ref
MIN
≠ 0 has been
programmed, the reference preset as a percentage will be
calculated on the basis of the difference between Ref
MAX
and Ref
MIN
following the value is added to Ref
MIN
.
The choice between reference presets can be made via the
digital inputs or via serial communication.
Description of choice:
Set the fixed reference(s) that is/are to be the option.
See P332, P333, P334 and P335 Description of choice,
where the description of the digital input set up is given.
3.4.1 Parameter Group 3-** Input/Output
317
Time out
Value:
1-99 s
[1-99]
10 s
[10]
Function:
If the value of the reference signal connected to the input,
terminal 1, falls below 50% of the setting in parameter 336
