NOTE!
This parameter cannot be adjusted while the motor is
running.
NOTE!
Max. output frequency cannot exceed 10% of the inverter
switching frequency (
14-01 Switching Frequency
).
4-20 Torque Limit Factor Source
Option:
Function:
Select an analog input for scaling the
settings in
4-16 Torque Limit Motor
Mode
and
4-17 Torque Limit Generator
Mode
from 0% to 100% (or inverse).
The signal levels corresponding to
0% and 100% are defined in the
analog input scaling, e.g., parameter
group 6-1*. This parameter is only
active when
1-00 Configuration Mode
is in
Speed Open-loop
or
Speed
Closed-loop

3.6.2 4-3* Motor Feedback Monitoring
The parameter group includes monitoring and handling of
motor feedback devices such as encoders, resolvers, etc.
4-30 Motor Feedback Loss Function
Option:
Function:
Select which reaction the Adjustable
frequency drive should take if a
feedback fault is detected. The
selected action is to take place when
the feedback signal differs from the
output speed where its range is
specified in
