How to Program
normal working range of the frequency converter.
Refer to the drawing in this section.
4-54 Warning Reference Low
Range:
-999999.999 - 999999.999
*
-999999.999
Function:
Enter the lower reference limit. When the actual
reference falls below this limit, the display indicates
Ref Low. The signal outputs can be programmed
to produce a status signal on terminal 27 or
29 and on relay output 01 or 02.
4-55 Warning Reference High
Range:
-999999.999 - 999999.999
*
999999.999
Function:
Enter the upper reference limit. When the actual
reference exceeds this limit, the disp lay reads
Ref High. The signal outputs can be programmed
to produce a status signal on terminal 27 or
29 and on relay output 01 or 02.
4-56 Warning Feedback Low
Range:
-999999.999 - 999999.999
*
-999999.999
Function:
Enter the lower feedbac k limit. When the feedback
falls b elow this limit, the display reads Feedb
Low. The signal outputs can be programmed
to produce a status signal on terminal 27 or
29 and on relay output 01 or 02.
4-57 Warning Feedback High
Range:
-999999.999 - 999999.999
*
999999.999
Function:
Enter the upper feedback limit. When the feedback
exceeds this lim it, the display reads Feedb
High. The signal outputs can be programmed
to produce a status signal on terminal 27 or
29 and on relay output 01 or 02.
4-58 Missing Mo tor Phase Function
Option:
Off [0]
*
On [1]
Function:
Select On, to display an alarm in the event of a
missing motor phase. Select Off, for no alarm in
the event of a missing motor phase. However,
if the motor runs on only two phases , it can be
damaged by overheating. Retaining the On setting
is therefore strongly recommended.
This parameter cannot be adjusted while
the motor is running.
" 4-6* Speed Bypass
Define the Speed Bypass area s for the ramps.
Some systems call for avoiding certain output
frequencies or speeds, due to resonance prob lems
in the system. A maximum of four frequency
or speed ranges can be avoided.
4-60 Bypass Speed From [RPM]
Array [4]
Range:
0-par. 4-13RPM
*
0RPM
Function:
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.
4-61 Bypass Speed From [Hz]
Array [4]
Range:
0-par. 4-14Hz
*
0Hz
Function:
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.
4-62 Bypass Speed to [RPM]
Array [4]
Range:
0-par. 4-13RPM
*
0RPM
*
