Programmable, see 31.24 Stall function

elected motor, the motor is operating in the stall region
because of excessive load or insufficient motor power. See also
A780.

The motor torque exceeded 31.25 Stall torque level for a time
longer than 31.28 Stall time while the speed feedback was
below 31.26 Stall speed level.

Check:

The motor load/mechanics (e.g. brake).

The drive ratings.

For correct field current.

The settings of 31.24 Stall function, 31.25 Stall torque level,
31.26 Stall speed level and 31.28 Stall time.

The settings for current and torque limits in group 30 Control limits.
