Parameters
3.5.3 4-5* Adj. Warnings
Define adjustable warning limits for current. Warnings are
shown on the display, programmed output, or fieldbus.
4-50 Warning Current Low
Range: Function:
0 A [ 0 - 194.0 Enter the I
LOW
A] 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 [ 0.0 - Enter the I
related 194.0 A] 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 - Enter the lower reference limit. When the
*
4999 ] actual reference drops below this limit, the
display indicates Ref
in parameter 16-94 Ext. Status Word. The
output relay or the digital output can be
configured to indicate this warning. The LCP
warning indicator light does not light when
this parameter set limit is reached.
4-55 Warning Reference High
Range: Function:
4999 [-4999 - Use this parameter to set a higher limit for the
*
4999 ] reference range.
When the actual reference exceeds this limit,
the display reads Reference High. Warning bit
19 is set in parameter 16-94 Ext. Status Word.
The output relay or the 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.
4-56 Warning Feedback Low

Function:
Use this parameter to set a
lower limit for the feedback
range.
When the feedback drops
below this limit, the display
reads Feedback Low. Warning

4-58 Missing Motor Phase Function
Option: Function:
[0] Off No alarm is shown if a missing motor phase occurs.
[1] On An alarm is shown if a missing motor phase occurs.

3.5.4 4-6* Speed Bypass
Define the speed bypass areas for the ramps. 3 frequency
ranges can be avoided.
4-61 Bypass Speed From [Hz]
Array[3]
Range: Function:
0 Hz [ 0 - 500 Hz] 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.
4-63 Bypass Speed To [Hz]
Array[3]
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.
Function:
configured to indicate this
warning. The LCP warning
indicator light does not light
up when this parameter set
limit is reached.
Function:
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 does not light
up when this parameter set
limit is reached.
