4-52 Warning Speed Low
Range: Function:
0 RPM* [ 0 -
par. 4-53
RPM]
Enter the n
LOW
value. When the motor speed
drops below this limit (n
LOW
), the display
reads Speed Low. The signal outputs can be
programmed 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 frequency converter.
Refer to Illustration 3.27.

RPM]
NOTICE
Any changes in parameter 4-13 Motor
Speed High Limit [RPM] reset the value
in parameter 4-53 Warning Speed High
to the same value as set in
parameter 4-13 Motor Speed High Limit
[RPM].
If a dierent value is needed in
parameter 4-53 Warning Speed High, it
must be set after programming of
parameter 4-13 Motor Speed High Limit
[RPM].
Enter the n
HIGH
value. When the motor speed
exceeds this limit (n
HIGH
), the display reads
Speed high. The signal outputs can be
programmed to produce a status signal on
terminal 27 or 29, and on relay output 01 or
02. Program the upper signal limit of the
motor speed, n
HIGH
, within the normal
working range of the frequency converter.
Refer to Illustration 3.27.
4-54 Warning Reference Low
Range: Function:
-999999.999* [ -999999.999 -
par. 4-55 ]
Enter the lower reference limit.
When the actual reference drops
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* [ 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

[ -999999.999 -
par. 4-57
ReferenceFeed-
backUnit]
Enter the lower feedback
limit. When the feedback
drops 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
ReferenceFeed-
backUnit*
[ par. 4-56 -
999999.999
ReferenceFeed-

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:

while the motor is running.
Shows an alarm if a motor phase is missing.
[0] * Disabled No alarm is shown if a missing motor phase
occurs.
[1] Trip 100 ms An alarm is shown if a missing motor phase
occurs.
