Programming Guide
Table 122: Range:
Min: -4999.000
4-57 Warning Feedback High
Default value: 4999.000
Conversion index: -3
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:
Min: -4999.000
4-58 Missing Motor Phase Function
Default value: [1] Trip 10 s
Conversion index: -
Table 124: Option:
[0] Off No alarm is shown if a missing motor phase occurs.
[1] Trip 10 s 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]
Default value: 0 Hz
Conversion index: -1
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:
Min: 0 Hz
4-63 Bypass Speed To [Hz]
Default value: 0 Hz
Conversion index: -1
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.
