3010 STALL
FUNCTION
Selects how the drive reacts to a motor stall condition.
The protection is active if the drive has operated in a
stall region (see the figure below) longer than the time
set by parameter 3012 STALL TIME.
In vector control the user defined limit = 2017 MAX
TORQUE 1 / 2018 MAX TORQUE 2 (applies for
positive and negative torques). See ACS355 User’s
manual (3AUA0000066143 [English]).
In scalar control the user defined limit = 2003 MAX
CURRENT. See ACS355 User’s manual
(3AUA0000066143 [English]).
The control mode is selected by parameter 9904
