Operating instructions

4-51 Warning Current High
Range: Function:
Application
dependent
*
[Application
dependant]
Enter the I
HIGH
value. When the motor
current exceeds this limit (I
HIGH
), the
display reads CURRENT HIGH. The
signal outputs can be programmed 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
Range: Function:
0 RPM
*
[Application dependant]
4-53 Warning Speed High
Range: Function:
Application
depend-
ent
*
[Applica-
tion
dependant]
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 the drawing in this section.
NOTE
Any changes in par. 4-13 Motor Speed High Limit [RPM]
will reset the value in par. 4-53 Warning Speed High to
the same value as set in par. 4-13 Motor Speed High Limit
[RPM].
If a different value is needed in par. 4-53 Warning Speed
High, it must be set after programming of
par. 4-13 Motor Speed High Limit [RPM]
4-54 Warning Reference Low
Range: Function:
-999999.999
*
[Application
dependant]
Enter the lower reference limit. When
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 and on relay output
01 or 02.
4-55 Warning Reference High
Range: Function:
999999.999
*
[Application
dependant]
Enter the upper reference limit. When
the actual reference exceeds this limit,
the display reads Ref High. The signal
outputs can be programmed to
produce a status signal on terminal 27
or 29 and on relay output 01 or 02.
4-56 Warning Feedback Low
Range: Function:
-999999.999
ProcessCtrlU-
nit
*
[Application
dependant]
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
Range: Function:
999999.999
ProcessCtrlU-
nit
*
[Application
dependant]
Enter the upper feedback limit.
When the feedback 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
Option: Function:
Displays an alarm in the event of a missing
motor phase.
[0] Disabled No alarm is displayed if a missing motor phase
occurs.
[2]
*
Trip 1000 ms
NOTE
This parameter cannot be adjusted while the motor is
running.
3.6.3 4-6* Speed Bypass
Define the Speed Bypass areas for the ramps.
Some systems call for avoiding certain output frequencies or
speeds, due to resonance problems in the system. A maximum
of four frequency or speed ranges can be avoided.
4-60 Bypass Speed From [RPM]
Array [4]
Range: Function:
Application
dependent
*
[Application
dependant]
Some systems call for avoiding
certain output speeds due to
resonance problems in the
system. Enter the lower limits of
the speeds to be avoided.
