= rated motor current
RATED
Min. limit = magnetising current in% of I
Max. limit = unit dependent limit in% of I

Function:
This function is relevant for all application configurations;
speed and process regulation. This is where to set the
current limit for motor operation.

Description of choice:
Set the desired % of current.
229
Frequency bypass, bandwidth
Value:
0 (OFF)-100%
0 (OFF)%
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.

The bypass band is the bypass frequency +/- half the set
bandwidth.

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%
Function:
Seven different reference presets can be programmed in
parameters 241 - 247 reference preset. The reference preset
is stated as a percentage of the value Ref
percentage of the other external references, depending on
the choice made in parameter 214. If a Ref
programmed, the reference preset as a percentage will be
calculated on the basis of the difference between Ref
and Ref
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.
