4-58 Missing Motor Phase Function
Option: Function:
NOTICE
This parameter cannot be adjusted while the
motor is running. Missing Motor Phase
Function is always disabled with PM.
Select On, to display an alarm in the event of a
missing motor phase. Select Off, for no missing motor
phase alarm. However the On setting is strongly
recommended to avoid motor damage.
[0] Off No alarm is displayed if a missing motor phase occurs.
[1] On An alarm is displayed if a missing motor phase occurs.

3.5.4 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. 3
frequency ranges can be avoided.
4-61 Bypass Speed From [Hz]
Array [3]
Range: Function:
0 Hz [0 - 400 Some systems call for avoiding certain output
*
Hz] speeds due to resonance problems in the
system. Enter the lower limits of the speeds to
be avoided.
4-63 Bypass Speed To [Hz]
Array [3]
Range: Function:
0 Hz [0 - 400 Some systems call for avoiding certain output
*
Hz] speeds due to resonance problems in the
system. Enter the upper limits of the speeds
to be avoided.
3.5.5 Semi-Automatic Bypass Speed Set-up
The Semi-Automatic Bypass Speed Set-up can be used to
facilitate the programming of the frequencies to be
skipped due to resonances in the system.
The following process is to be carried out:
1. Stop the motor.
