ABB ACS850 - Mot Therm Prot

Parameters 145
Alarm The drive generates alarm SAFE TORQUE OFF. 2
No No action taken. 3
30.08 Cross connection Selects how the drive reacts to incorrect input power and
motor cable connection (i.e. input power cable is connected
to drive motor connection).
No No action taken. 0
Fault The drive trips on fault CABLE CROSS CON. 1
30.09 Stall function Selects how the drive reacts to a motor stall condition. The
protection wakes up if
• the drive is at stall current limit (defined by parameter
30.10 Stall curr lim) or 06.05 Limit word1 differs from 0
• the output frequency is below the level set by parameter
30.11 Stall freq hi, and
• the conditions above have been valid longer than the time
set by parameter 30.12 Stall time.
See section Stall protection (parameters 30.09…30.12) on
page 43.
30.10 Stall curr lim Stall current limit in percent of the nominal current of the
motor. See parameter 30.09 Stall function.
0.0 … 1600.0% Stall current limit. 10 = 1%
30.11 Stall freq hi Stall frequency limit. See parameter 30.09 Stall function.
0.5 … 1000.0 Hz Stall frequency limit. 10 = 1 Hz
30.12 Stall time Stall time. See parameter 30.09 Stall function.
0 … 3600 s Stall time. 1 = 1 s
31
31 Mot therm prot
Motor temperature measurement and thermal protection
settings.
31.01 Mot temp1 prot Selects how the drive reacts when motor overtemperature is
detected by motor thermal protection 1.
No Motor thermal protection 1 inactive. 0
Alarm The drive generates alarm MOTOR TEMPERATURE when
the temperature exceeds the alarm level defined by
parameter 31.03 Mot temp1 almLim.
1
Fault The drive generates alarm MOTOR TEMPERATURE or trips
on fault MOTOR OVERTEMP when the temperature exceeds
the alarm/fault level defined by parameter 31.02 Mot temp1
almLim / 31.03 Mot temp1 almLim (whichever is lower).
