Function:
Enter the n value. When the motor
HIGH
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). Programme the upper signal limit
of the motor speed, n
normal working range of the frequency
converter. Refer to the drawing in this
section.
Function:
[Application Enter the lower reference limit. When
dependant] the actual reference falls below this
limit, the display indicates Ref Low.
The signal outputs can be program-
med to produce a status signal on
terminal 27 or 29 (FC 302 only) and
on relay output 01 or 02 (FC 302
only).
Function:
[Application Enter the upper reference limit. When
the actual reference exceeds this limit,
