How to Program
4-50 Warning Current Low
Range:
0.00 - par. 4-51 A
*
0.00A
Function:
When the motor current is b elow this limit,
I
LOW
, the display reads C UR RENT LOW. It is
possible to program the signal outputs to produce
a status signal on terminal 27 or 29 as well
as on relay output 01 or 0 2.
4-51 Warning Current High
Range:
Par. 4-50 - par. 16-37 A
*
par. 16-3 7 A
Function:
If the motor current exceeds this limit (I
HIGH
), the
display reads CURRENT HIGH. It is possible to
program the signal outputs to produce a status signal
on term inal 27 or 29 and on relay output 01 or 02.
4-52 Warning Speed Low
Range:
0-par. 4-53RPM
*
0RPM
Function:
When the m otor speed is below the lim it, n
LOW
the display reads SP EED LOW. It is possible to
program the signal outputs to produce a status
signal on terminal 27 or 29 and on relay
output 01
or 02.Program the lower signal limit of the motor
speed, n
LOW
, within the normal working range of
the adjustable frequency drive.
See drawing.
4-53 Warnin g Speed High
Range:
Par. 4-52 - par. 4-13 RPM
*
par. 4-13 RPM
Function:
When the motor speed is above the limit, n
HIGH
,
the display reads SPEED HIGH. It is possible to
program the signal outputs to produce a status
signal on terminal 27 or 29 a nd on relay output
01 or 02. Program the upper signal limit of the
motor speed, n
HIGH
, within the normal working
range of the adjustable frequency drive.
4-54 Warning Reference Low
Range:
-999999.999 - 999999.999
*
-999999.9 99
Function:
If the actua l reference is below this limit, the
display indicates Ref Low. The signal outputs can
be programmed to produce a status signal on the
digital outputs and the relay outputs.
4-55 Warn in g Reference High
Range:
-999999.999 - 999999.999
*
999999.9 99
Function:
If the actual refe rence exceeds this limit, the
display indicates Ref High. The signal outputs can
be programmed to produce a status signal on the
digital outputs and the relay outputs.
4-56 Warnin g Feedback Low
Range:
-999999.999 - 999999.999
*
-999999.9 99
Function:
If the feedback is below this limit, the display
indicates Feedb Low. The signal outputs can be
programmed to produce a status signal on the
digital outputs and the relay outputs.
4-57 Warning Feedback High
Range:
-999999.999 - 999999.999
*
999999.9 99
*
