4-50 Warning Current Low
Range: Function:
on the digital output or the relay
output.
4-51 Warning Current High
Range: Function:
Size
related*
[ 0 - 500.00
A]
Enter the I
HIGH
value. When the
compressor 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:
0* [0 - 6010 ] Enter the lower reference limit.
When the actual reference drops
below this limit, the display
indicates Ref
Low
. Terminal 27 and 29
could not be set to output. Only
AO42/45 could be set to DO mode.
4-55 Warning Reference High
Use this parameter to set a higher limit for the reference range.
Range: Function:
6010* [0 - 6010 ] When the actual reference exceeds
this limit, the display reads
Reference High. Warning bit 19 is
set in parameter 16-94 Ext. Status
Word. Output relay can be
congured to indicate this warning.
The LCP warning light does not
light when this parameter set limit
is reached.
4-56 Warning Feedback Low
Use this parameter to set a lower limit for the feedback range.
Range: Function:
0
ProcessCtrl
Unit*
[0 - 6010
ProcessCtrlUnit
]
When the feedback drops below
this limit, the display reads
Feedback Low. Warning bit 6 is set
in parameter 16-94 Ext. Status Word.
Output relay can be congured to
indicate this warning. The LCP
warning light does not light when
this parameter set limit is reached.
4-57 Warning Feedback High
Use this parameter to set a higher limit for the feedback range.
Range: Function:
6010
ProcessCtrl
Unit*
[0 - 6010
ProcessCtrlUnit
]
When the feedback exceeds this
limit, the display reads Feedback
High. Warning bit 5 is set in
4-57 Warning Feedback High
Use this parameter to set a higher limit for the feedback range.
Range: Function:
parameter 16-94 Ext. Status Word.
Output relay can be congured to
indicate this warning. The LCP
warning light does not light 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]
Some systems call for avoiding certain output speeds due to
resonance problems in the system.
Range: Function:
0 Hz [ 0 - 500 Hz] Enter the lower limits of the speeds
to be avoided.
4-63 Bypass Speed To [Hz]
Some systems call for avoiding certain output speeds due to
resonance problems in the system.
Range: Function:
0 Hz* [ 0 - 500 Hz] Enter the upper limits of the speeds
to be avoided.
3.6 Main Menu - Digital In/Out - Group 5
3.6.1 5-0* Digital I/O Mode
Parameters for conguring the input and output using
NPN and PNP.
NOTICE
These parameters cannot be adjusted while the
compressor is running.
5-00 Digital Input Mode
Set NPN or PNP mode for digital inputs 18, 19, 27 and 29. Digital
input mode.
Option: Function:
[0] * PNP Action on positive directional pulses
(0). PNP systems are pulled down to
GND.
