med to produce a status signal on terminal 27 or
29 and on relay output 01 or 02. Refer to the
drawing in this section.
4-52 Warning Speed Low
Value:
0 - par. 4-13
Function:
Enter the n value. When the motor speed ex-
LOW
ceeds this limit (n ), the display reads SPEED
LOW
LOW. 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).
4-53 Warning Speed High
Value:
Par. 4-52 - par. 4-13
Function:
Enter the n value. When the motor speed ex-
HIGH

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
normal working range of the frequency converter.
Refer to the drawing in this section.
4-54 Warning Reference Low
Value:
-999999.999 - par. 4-55
Function:
Enter the lower reference limit. When the actual
reference falls below this limit, the display indi-
cates Ref Low. The signal outputs can be pro-
grammed to produce a status signal on terminal
27 or 29 and on relay output 01 or 02.
4-55 Warning Reference High
Value:
Par. 4-54 - 999999.999
Function:
Enter the upper reference limit. When the actual
reference exceeds this limit, the display reads Ref
High. The signal outputs can be programmed to

4-56 Warning Feedback Low
Value:
-999999.999 - par. 4-57
Function:
Enter the lower feedback limit. When the feedback
falls 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
Value:
Par. 4-56 - 999999.999
Function:
Enter the upper feedback limit. When the feed-
back 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
Value:
Off
On
Function:
Select On, to display an alarm in the event of a
missing motor phase. Select Off, for no alarm in
the event of a missing motor phase. However, if
the motor runs on only two phases, it can be dam-
aged by overheating. Retaining the On setting is
therefore strongly recommended.
This parameter cannot be adjusted while the mo-
tor is running.
4-6* Speed Bypass
Define the Speed Bypass areas for the ramps.
Some systems call for avoiding certain output fre-
quencies or speeds, due to resonance problems in
the system. A maximum of four frequency or
speed ranges can be avoided.
