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 100ms. Select 100 ms for fast detection of missing motor phase.
[2] Trip 1000 ms Trips after 1000 ms. Select 1000 ms for slow detection of missing motor phase.
[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.
