3.6.4 4-6* Speed Bypass
Some systems call for avoiding certain output frequencies
or speeds, due to resonance problems in the system. A
maximum of 4 frequency or speed ranges can be avoided.

Function:
[ par. 4-56 - Enter the upper feedback
999999.999 limit. When the feedback
ReferenceFeed- exceeds this limit, the
backUnit] display reads Feedb High.
The signal outputs can
be programmed to
produce a status signal
on terminal 27 or 29 (FC
302 only) and on relay
output 01 or 02 (FC 302
only).
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Displays alarm 30, 31 or 32 in the event of a
missing motor phase. It is strongly
recommended to enable to avoid motor
damage.
The frequency converter does not issue a
missing motor phase alarm. Not recommended
due to risk of motor damage.
For a quick detection time and alarm in the
event of a missing motor phase.
For a slow detection time and alarm in the
event of a missing motor phase.
The frequency converter detects automatically
when the motor is disconnected and resumes
operation once the motor is connected again.
Function:
[ 0 - par. Some systems call for avoiding certain
output speeds due to resonance
problems in the system. Enter the
lower limits of the speeds to be
avoided.
