the decelerationtime can’t be shortened.L3-04 cannot be set to 2

Stall prevention
selection during running
When setting 1 or 2 (enabled) is selected, deceleration is
started if the current of the stall preventionlevel during
operation continues for more than 100 ms. The motor is
accelerated back to the referencefrequency again when
the current falls below this level.

Sets the number of auto restart attempts.Automatically

The fault restart function automatically restarts the Inverter
even when an internal fault occurs duringInverter operation.
Use this function only when continuing operation is more
important than possiblydamaging the Inverter.The fault
restart function is effective with the following faults.With
other faults, the protective operationswill engage immediately
without attempting to restart operation.
