Range:
Function:
0 RPM
*
[Application
dependant]
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:
Application
dependent
*
[Application
dependant]
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).
Program the upper signal limit of
the motor speed, n
HIGH
, within the
normal working range of the
adjustable frequency drive. Refer to
the drawing in this section.
4-54 Warning Reference Low
Range:
Function:
-999999.999
*
[Application
dependant]
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
*
[Application
dependant]
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
ReferenceFeed-

*
[Application
dependant]
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
ReferenceFeed-

*
[Application
dependant]
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 (alarm 30,
31 or 32). Select disabled for no missing motor phase alarm. It is
strongly recommended to make an active setting to avoid motor
damage.
Option:
Function:
[0]
Disabled
No alarm is displayed if a
missing motor phase occurs.
[1]
Trip 100 ms
Trips after 100 ms. Select 100
ms for fast detection of
missing motor phase.
[2]
Trip 1000 ms
Trips after 1000 ms. Select
1000 ms for slow detection of
missing motor phase.
[3]
