FC 300 Design Guide
Function:
Select an analog input for scaling the settings in
par. 4-19 from 0% to 100% (or inverse). The sig-
nal levels corresponding to 0% and 100% are de-
fined in the analog input scaling, e.g. par. group
6-1*. This parameter is only active when par.
1-00 Configuration Mode is in Torque Mode.
4-3* Motor Feedback Monitoring
The parameter group includes monitoring and
handling of motor feedback devices as encoders,
resolvers etc.
4-30 Motor Feedback Loss Function
Value:
Disabled
Warning
Trip
Function:
Select which reaction the frequency converter
should take in the case a feedback fault is detec-
ted. The selected action will take place if the feed-
back signal differs from the output speed with
more than specified in par. 4-31 during the time
set in par. 4-32.
4-31 Motor Feedback Speed Error
Value:
1-600 RPM
Function:
Select the max allowed tracking error in speed
from the calculated and the actual mechanical
shaft output speed.

4-32 Motor Feedback Loss Timeout
Value:
0.00 - 60.00 sec
Function:
Set the timeout value allowing the speed error set
in par. 4-31 to be exceeded.
4-5* Adjustable Warnings
Define adjustable warning limits for current,
speed, reference and feedback. Warnings are
shown on the display, programmed output or se-
rial bus.
Warnings are shown on display, programmed out-
put or serial bus.
4-50 Warning Current Low
Value:
0.00 - par. 4-51
Function:
Enter the I value. When the motor current falls
LOW
below this limit (I ), the display reads CURRENT
LOW
LOW. 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.
4-51 Warning Current High
Value:
Par. 4-50 - par. 16-37
Function:
Enter the I value. When the motor current ex-
HIGH
ceeds this limit (I ), the display reads CUR-
HIGH
RENT HIGH. The signal outputs can be program-
