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
3630
ALTERNATING
TIMER
0.0…1000.0 h 1 0.0 h
Defines the time interval for the timer to switch between On (1) and Off (0) states
(starting from the On state), based on the selections ALTERNATING or
ALT+BOOSTER in the timer source parameters
3626 ... 3629 .
• ALTERNATING – Alternating time period is enabled. The time periods P1, P2,
P1+P2 and P3 are ignore for the specific timed function.
• ALT+BOOSTER – Alternating time period and booster times are enabled
simultaneously.
Group 37: User load curve
Code Description Range Resolution Default 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.
