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.

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.

Function:
[Application Enter the upper feedback
dependant] 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).
Function:
Disabled No alarm is displayed if a
missing motor phase
occurs.
Trip 100 ms Trips after 100 ms. Select
100ms for fast detection of
missing motor phase.
Trip 1000 ms Trips after 1000ms. Select
1000ms for slow detection
of missing motor phase.
