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. Refer to .
NOTE
Any changes in
4-13 Motor Speed High Limit [RPM]
will reset
the value in
to the same value as
set in
4-13 Motor Speed High Limit [RPM]
If a different value is needed in

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 and on relay
output 01 or 02.
