Programming
Description of choice:
Set the desired % of current.
NB!:
The setting is limited to 160%, but for motors
with2poles(0.55+1.1kW),thesettingis
limited to 120% which corresponds to 160%
torque, setting 73% corresponds to 100% torque.
229 Frequency bypass, bandwidth
(FREQ BYPASS B.W.)
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 these frequency bypasses.
Description of choice:
The bypass band is the bypass frequency +/-
half the set bandwidth.
A percentage of the setting in parameters
230-231 is selected.
230 Frequency bypass 1

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.

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
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
