4-51 Warning Current High
Range:
Function:
par. 16-37 A
*
[Par. 4-50 - par.
16-37]
Enter the I
HIGH
value. When the motor current exceeds this limit, the display reads
Current High
. The signal
outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output
01 or 02 (FC 302 only). Refer to the drawing in this section.
4-52 Warning Speed Low
Range:
Function:
0 RPM
*
[0 - par. 4-13]
Enter the n
LOW
value. When the motor speed exceeds this limit, the display reads
Speed Low
. The signal outputs
can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output 01 or 02
(FC 302 only).
4-53 Warning Speed High
Range:
Function:
par. 4-13 RPM
*
[Par. 4-52 - par.
4-13]
Enter the n
HIGH
value. When the motor speed exceeds this limit, the display reads
Speed High
. The signal outputs
can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output 01 or 02
(FC 302 only). Programme the upper signal limit of the motor speed, n
HIGH
, within the normal working range of
the frequency converter. Refer to the drawing in this section.
4-54 Warning Reference Low
Range:
Function:
-999999.999
*
[-999999.999 - par.
4-55]
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 (FC 302 only) and on
relay output 01 or 02 (FC 302 only).
4-55 Warning Reference High
Range:
Function:
999999.999
*
[Par. 4-54 -
999999.999]
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 (FC 302 only) and on relay
output 01 or 02 (FC 302 only).
4-56 Warning Feedback Low
Range:
Function:
-999999.999
*
[-999999.999 - par.
4-57]
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 (FC 302 only) and on relay output
01 or 02 (FC 302 only).
4-57 Warning Feedback High
Range:
Function:
999999.999
*
[Par. 4-56 -
999999.999]
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 (FC 302 only) and on relay output
01 or 02 (FC 302 only).
4-58 Missing Motor Phase Function
Displays an alarm in the event of a missing motor phase.
[0]
Off
Select [Off] for no missing motor phase alarm. However the [On] setting is strongly recommended to avoid
motor damage.
[1]
*
On
Select [On] to display an alarm in the event of a missing motor phase.
This parameter cannot be adjusted while the motor is running.
2.7.5. 4-6* Speed Bypass
Define the Speed Bypass areas for the ramps.
