Parameter Descriptions

6.5 Parameters: 4-** Limits/Warnings

6.5.1 4-1* Motor Limits
Define torque, current and speed limits for the motor, and
the reaction of the frequency converter when the limits are
exceeded.
A limit may generate a message on the display. A warning
will always generate a message on the display or on the
fieldbus. A monitoring function may initiate a warning or a
trip, upon which the frequency converter will stop and
generate an alarm message.
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.

4-21 Speed Limit Factor SourceOption
Option: Function:
Select an analog input for scaling
the settings in 4-19 Max Output
Frequency from 0% to 100% (or vice
versa). 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 Torque

6.5.2 4-5* Adjustable Warnings
Use these parameters to adjust warning limits for current,
speed, reference and feedback. Warnings that are shown
on the display can be programmed as an output or sent
via serial bus.
