FCM 300 Series
MG.03.B6.2G - VLT is a registered Danfoss trademark
229 Frequency bypass, bandwidth
(FREQ BYPASS B.W.)
Settings:
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 fre/- half
the set bandwidth.
A percentage of the setting in parameters 230-231
is selected.
230 Frequency bypass 1 (FREQ. BYPASS 1)
231 Frequency bypass 2 (FREQ. BYPASS 2)
Settings:
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.

NOTE!
For motors with 2 poles (0.55 + 1.1 kW), the setting
is limited to 120% which corresponds to 160%
torque, setting 73% corresponds to 100% torque.
