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:
[0] Disabled
[1] Trip 100 ms
[2] Trip 1000 ms
[3] Trip 100 ms lim 3 phase detec.
NB!
This parameter cannot be adjusted while the motor is running.
3.6.5 4-6* Speed Bypass
Define the Speed Bypass areas for the ramps.
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:
No alarm is displayed if a missing motor phase occurs.
Trips after 100ms. Select 100 ms for fast detection of missing motor phase.
Trips after 1000 ms. Select 1000 ms for slow detection of missing motor phase.
