3.5.3 4-5* Adj. Warnings
Dene adjustable warning limits for current. Warnings are
shown on the display, programmed output, or
eldbus.
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 lower reference limit. When the
actual reference drops below this limit, the
display indicates Ref
Low
. Warning 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 indicator light does not light when
this parameter set limit is reached.
4-55 Warning Reference High
Range: Function:
4999 * [-4999 -
4999 ]
Use this parameter to set a higher limit for the
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
congured 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
Range: Function:
-4999
ProcessCtrlUnit
*
[-4999 - 4999
ProcessCtrlUnit]
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
bit 6 is set in
parameter 16-94 Ext. Status
Word. The output relay or
digital output can be
4-56 Warning Feedback Low
Range: Function:
congured to indicate this
warning. The LCP warning
indicator light does not light
up 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
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
congured to indicate this
warning. The LCP warning
indicator light does not light
up 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.
3.5.4 4-6* Speed Bypass
Dene 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.
