regenerative operation of the motor, and so that the generated
current does not exceed the current limit set in par. 4-18. See
ramp-up time in par. 3-41.

exceed the setting in par. 4-11
Only par. 4-11 or 4-12 will be displayed depending on other pa-
rameters set in the Main Menu, and depending on default set-
tings specific to global geographical locations.
NOTE
The output frequency value of the adjustable frequency drive must not exceed a
value higher than 1/10 of the switching frequency.
Function:
The AMA function optimizes dynamic motor performance by au-
tomatically optimizing the advanced motor parameters (par.
1-30 to par. 1-35) while the motor is stationary.
