Danfoss VLT Midi Drive FC 280 Programming Guide

4-50 Warning Current Low
Range: Function:
0 A* [ 0 - 194.0
A]
Enter the I
LOW
value. When the motor current
drops below this limit, a bit in the status word
is set. This value can also be programmed to
produce a signal on the digital output or the
relay output.
4-51 Warning Current High
Range: Function:
Size
related*
[ 0.0 -
194.0 A]
Enter the I
HIGH
value. When the motor
current exceeds this limit, a bit in the
status word is set. This value can also be
programmed to produce a signal on the
digital output or the relay output.
4-54 Warning Reference Low
Range: Function:
-4999* [-4999 -
4999 ]
Enter the low reference limit. When the actual
reference drops below this limit, the display
shows Ref
LOW
. Bit 20 is set in
parameter 16-94 Ext. Status Word. The output
relay or the digital output can be congured
to indicate this warning. The LCP warning
light is not turned on when this parameter set
limit is reached.
4-55 Warning Reference High
Range: Function:
4999* [-4999 -
4999 ]
Use this parameter to set a high limit for the
reference range. When the actual reference
exceeds this limit, the display shows Ref
HIGH
. Bit
19 is set in parameter 16-94 Ext. Status Word.
The output relay or the digital output can be
congured to indicate this warning. The LCP
warning light is not turned on when this
parameter set limit is reached.
4-56 Warning Feedback Low
Range: Function:
-4999
ProcessCtrlUnit*
[-4999 - 4999
ProcessCtrlUnit]
Use this parameter to set a
low limit for the feedback
range. When the feedback
drops below this limit, the
display shows Feedb Low. Bit
6 is set in
parameter 16-94 Ext. Status
Word. The output relay or the
digital output can be
congured to indicate this
warning. The LCP warning
light is not turned on when
this parameter set limit is
reached.
4-57 Warning Feedback High
Range: Function:
4999
ProcessCtrlUnit*
[-4999 - 4999
ProcessCtrlUnit]
Use this parameter to set a
high limit for the feedback
range. When the feedback
exceeds this limit, the display
reads Feedb High. Bit 5 is set
in parameter 16-94 Ext. Status
Word. The output relay or the
digital output can be
congured to indicate this
warning. The LCP warning
light is not turned on when
this parameter set limit is
reached.
4-58 Missing Motor Phase Function
Option: Function:
[0] O No alarm is shown if a missing motor phase occurs.
[1] * On An alarm is shown if a missing motor phase occurs.
4-61 Bypass Speed From [Hz]
Range: Function:
0 Hz* [ 0 - 500
Hz]
Some systems call for avoiding certain
output speeds due to resonance problems
in the system. Enter the lower limits of the
speeds to be avoided.
4-63 Bypass Speed To [Hz]
Range: Function:
0 Hz* [ 0 - 500
Hz]
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.
4-64 Semi-Auto Bypass Set-up
Option: Function:
[0] * O
[1] Enable
