Function:
Enter the n value. When the motor speed
LOW
drops below this limit (n
LOW
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 , within the normal
LOW
working range of the frequency converter.
Refer to Illustration 3.27.

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 different 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 value. When the motor speed
HIGH
exceeds this limit (n ), the display reads
