Description
Selects how the drive reacts to a motor stall condition. The
protection wakes up if the drive has operated in a stall
region (see the figure below) longer than the time set by
parameter 3012 STALL
In vector control the user defined limit =
TORQUE 1 / 2018 MAX TORQUE 2
and negative torques).
In scalar control the user defined limit =
CURRENT.
The control mode is selected by parameter
CTRL MODE.

0.95 User defined limit
Protection is inactive.
The drive trips on fault
motor coasts to stop.
The drive generates alarm
Defines the frequency limit for the stall function. See
parameter 3010 STALL
Frequency
Defines the time for the stall function. See parameter
STALL FUNCTION.
Time
Selects how the drive reacts to underload. The protection
wakes up if:
• the motor torque falls below the curve selected by
parameter 3015 UNDERLOAD
• output frequency is higher than 10% of the nominal motor
frequency and
• the above conditions have been valid longer than the time
set by parameter 3014 UNDERLOAD
Protection is inactive.
