4-54 Warning Reference Low
Range:
Function:
-999999.99
9 N/A*
[-999999.999 - par. 4-55 N/A]
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:
Function:
999999.999
N/A*
[par. 4-54 - 999999.999 N/A]
Enter the upper reference limit. When the actual reference exceeds this limit, the display 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:
Function:
-999999.99
9 Proc-
essCtrlU-
nit*
[-999999.999 - par. 4-57 Proc-
essCtrlUnit]
Enter the lower feedback limit. When the feedback falls below 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:
Function:
999999.999
ProcessCtr-
lUnit*
[par. 4-56 - 999999.999 ProcessCtr-
lUnit]
Enter the upper feedback limit. When the feedback exceeds this limit, 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 Motor Phase Function
Option:
Function:
Displays an alarm in the event of a missing motor phase.
Select 100 ms to have a short detection time and alarm in the event of a missing motor phase. 100
ms is recommended for hoisting applications.
[0]
Disabled
No alarm is displayed if a missing motor phase occurs.
[2] *
Trip 1000 ms
NB!
This parameter cannot be adjusted while the motor is running.
2.6.4 4-6* Speed Bypass
Define the Speed Bypass areas for the ramps.
Some systems call for avoiding certain output frequencies or speeds, due to resonance problems in the system. A maximum of four frequency or speed
ranges can be avoided.
4-60 Bypass Speed From [RPM]
Array [4]
Range:
Function:
0 RPM*
[0 - par. 4-13 RPM]
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.
