[Application
dependant]
Enter the upper feedback
limit. When the feedback
exceeds this limit, the 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).
4-58 Missing Motor Phase Function
Displays an alarm in the event of a missing motor phase (alarm
30, 31 or 32). Select disabled for no missing motor phase alarm.
It is strongly recommended to make an active setting to avoid
motor damage.
Option: Function:
[0] * Disabled No alarm is displayed if a
missing motor phase
occurs.
[1] Trip 100 ms Trips after 100 ms. Select
100ms for fast detection of
missing motor phase.
[2] Trip 1000 ms Trips after 1000ms. Select
1000ms for slow detection
of missing motor phase.
[3] Trip 100ms 3ph
detec.
NOTE!
This parameter cannot be adjusted while the motor is
running.
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 four frequency or speed ranges can be
avoided.
