Table 122: Range:
4-57 Warning Feedback High
Change during operation: True
Use this parameter to set a higher limit for the feedback range. When the feedback exceeds this limit, the display reads Feedback
High. Warning bit 5 is set in parameter 16-94 Ext. Status Word. The output relay or digital output can be configured to indicate this
warning. The LCP warning indicator light is not turned on when this parameter set limit is reached.
Table 123: Range:
4-58 Missing Motor Phase Function
Default value: [1] Trip 10 s
Change during operation: False
Table 124: Option:
No alarm is shown if a missing motor phase occurs.
The drive performs a scans for 10 s to detect a missing motor phase. When a missing motor phase is detected,
the drive trips.
4.6.4 4-6* Speed Bypass
Define the speed bypass areas for the ramps. 3 frequency ranges can be avoided.
4-61 Bypass Speed From [Hz]
Change during operation: True
Enter the lower limits of the speeds to be avoided. Some systems call for avoiding certain output speeds due to resonance problems
in the system.
Table 125: Range:
4-63 Bypass Speed To [Hz]
Change during operation: True
Some systems call for avoiding certain output speeds due to resonance problems in the system. Enter the upper limits of the speeds
to be avoided.
Table 126: Range:
4-64 Semi-Auto Bypass Set-up
Change during operation: True
