Description
Defines supervision of a user adjustable load curve (motor
torque as a function of frequency). The curve is defined by
five points. See section
Defines supervision mode for the user adjustable load
curve.

Supervision not active
Supervision for the torque dropping below the underload
curve
Supervision for the torque exceeding the overload curve
Supervision for the torque dropping below the underload
curve or exceeding the overload curve
Defines the action wanted during load supervision
A fault is generated when the condition defined by
USER LOAD C MODE has been valid longer than the time
set by USER LOAD C MODE.
3703
An alarm is generated when the condition defined by
USER LOAD C MODE has been valid longer than half of the
time set by USER LOAD C MODE.
3703
Defines the time limit for generating a fault. Half of this time
is used as the limit for generating an alarm.
Time

Defines the torque value of the first underload curve
definition point. Must be smaller than
HIGH 1.
