For 87 Hz operation with 230/400 V motors, set
the nameplate data for 230 V. Adapt parameter

Maximum reference to the 87 Hz application.
NB!:
If a delta connection is used, the rated
motor frequency for the delta connected
must be selected.
NB!:
If the setting in parameter 102-109 is changed,
the parameters 110-118 will return to factory
setting. If using special motor characteristics a
change in parameter 102-109 affects parameter 422.

Function:
If this function is used, the frequency converter
automatically sets the necessary control parameters
(parameters 108/109) with the motor stationary.
Automatic motor adaptation ensures optimum
use of the motor.
For the best possible adaptation of the frequency
converter, it is recommended to run AMA
on a cold motor.
The AMA function is activated by pressing the
[START] key after selecting [1] or [2].
See also section Automatic motor adaptation.
The section Automatic motor adaption, AMA, via
AKD software dialog shows how automatic motor
adaptation can be activated by means of AKD Software
Dialog. After a normal sequence, the display will read
"ALARM 21". Press the [STOP/RESET] key. The
frequency converter is now ready for operation.
