Parameters 197
30.09 Stall function Selects how the drive reacts to a motor stall condition.
A stall condition is defined as follows:
• The drive is at stall current limit (
30.10 Stall curr lim ) , and
• 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 80 .
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 .
Note: Setting the limit below 10 Hz is not recommended.
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 Motor 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
(0x4310) if the temperature exceeds the alarm level defined
by parameter 31.03 Mot temp1 almLim .
1
Fault The drive generates alarm MOTOR TEMPERATURE
(0x4310) or trips on fault MOTOR OVERTEMP (0x4310) if
the temperature exceeds the alarm/fault level defined by
parameter
31.02 Mot temp1 almLim / 31.03 Mot temp1
almLim (whichever is lower).
