Group 37: User Load Curve
This new group defines supervision of user adjustable load curves (motor torque as a function of frequency). The
curve is defined by five points. - The function replaces deleted underload parameters 3013…3015

Code Description

S
3701 USER LOAD C MODE
0 . . .3
1
0
Supervision mode for the user adjustable load curves . This functionality replaces the former underload
supervision in Group 30: FAULT FUNCTIONS .
0 = NOT SEL – Supervision is not active .
1 = UNDERLOAD – Supervision for the torque dropping below the underload curve .
2 = OVERLOAD – Supervision for the torque exceeding the overload curve .
3 = BOTH – Supervision for the torque dropping below the underload curve or exceeding the overload curve .
3702 USER LOAD C FUNC
1, 2
1
1
Action wanted during load supervision .
1 = FAULT – A fault is generated when the condition defined by 3701 USER LOAD C MODE has been valid longer than the time set by
3703 USER LOAD C TIME .
2 = ALARM – An alarm is generated when the condition defined by 3701 USER LOAD C MODE has been valid longer than half of the time
defined by 3703 USER LOAD C TIME.
3703 USER LOAD C TIME
20 s
Defines the time limit for generating a fault. Half of this time is used as the limit for generating an alarm.
3704 LOAD FREQ 1
5 Hz
Defines the frequency value of the first curve definition point. Must be smaller than 3707 LOAD FREQ 2.
3705 LOAD TORQ LOW 1
10%
Defines the torque value of the first underload curve definition point. Must be smaller than 3706 LOAD TORQ HIGH 1.
3706 LOAD TORQ HIGH 1
300%
Defines the torque value of the first overload curve definition point.
3707 LOAD FREQ 2
25%
Defines the frequency value of the second curve definition point. Must be smaller than 3710 LOAD FREQ 3.
3708 LOAD TORQ LOW 2
15%
Defines the torque value of the second underload curve definition point. Must be smaller than 3709 LOAD TORQ HIGH 2.
3709 LOAD TORQ HIGH 2
300%
Defines the torque value of the second overload curve definition point.
3710 LOAD FREQ 3
43 Hz
Defines the frequency value of the third load curve definition point.
3711 LOAD TORQ LOW 3
25%
Defines the torque value of the third underload curve definition point. Must be smaller than 3712 LOAD TORQ HIGH 3.
3712 LOAD TORQ HIGH 3
300%
Defines the torque value of the third overload curve definition point.
3713 LOAD FREQ 4
50 Hz
Defines the frequency value of the fourth load curve definition point.
3714 LOAD TORQ LOW 4
30%
Defines the torque value of the fourth underload curve definition point. Must be smaller than 3715 LOAD TORQ HIGH 4.
3715 LOAD TORQ HIGH 4
300%
Defines the torque overvalue of the fourth load curve definition point.
3716 LOAD FREQ 5
500 Hz
Defines the frequency value of fifth load curve definition point.
3717 LOAD TORQ LOW 5
30%
Defines the torque value of the fifth underload curve definition point. Must be smaller than 3718 LOAD TORQ HIGH 5.
3718 LOAD TORQ HIGH 5
300%
Defines the torque value of the fifth overload curve definition point.
