NOTICE
Any changes in
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
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. Programme the upper signal limit of the
motor speed, n
HIGH
, within the normal
working range of the frequency converter.
