FC 301: The Complete AMA does not include X
measurement, but the X
the motor database. Par. 1-35 may be adjusted
to obtain optimal start performance.
Select Reduced AMA if a reduced test is to be
carried out, in which only the stator resistance
R in the system is determined.
s
AMA cannot be carried out while the motor is running.
AMA cannot be carried out on permanent
magnet motors.
Activate the AMA function by pressing [Hand
on] after selecting [1] or [2]. See also section
Automatic Motor Adaptation. After a normal
sequence, the display will read, "Press [OK] to finish
AMA". After pressing the [OK] key the frequency
converter is now ready for operation.
NB!:
It is important to set motor par. 1-2*
correctly, since these form part of the
AMA algorithm. For optimum dynamic
motor performance, an AMA must be carried
out. It may take up to 10 min, depending on
the power rating of the motor.
NB!:
Avoid externally generating torque
during AMA.
NB!:
If one of the settings in par. 1-2*
is changed, par. 1-30 to 1-39 will
return to default setting.
3-02 Minimum Reference
Range:
-100000.000 - par. 3-03
Function:
The Minimum reference is the minimum
value obtained by the sum of all references.
Minimum reference is only active if Min -
Max [0] is set in par. 3-00.

3-03 Maximum Reference
Range:
Par. 3-02 - 100000.000
Function:
The Maximum reference is the highest value
obtained by the sum of all references. The unit
follows the choice of configuration in par. 1-00.

3-41 Ramp 1 Ramp up Time
Range:
0.01 - 3600.00 s
Function:
The ramp-up time is the acceleration time from 0
RPM to the rated motor speed nM,N (par. 1-25),
provided that the output current does not reach
the torque limit (set in par. 4-16). The value 0.00
corresponds to 0.01 s in speed mode.
3-42 Ramp 1 Ramp Down Time
Range:
0.01 - 3600.00 s
Function:
The ramp-down time is the deceleration time from
the rated motor speed n
M,N
provided that there is no over-voltage in the inverter
due to regenerative operation of the motor, or if the
generated current reaches the torque limit (set in
par. 4-17). The value 0.00 corresponds to 0.01 s in
speed mode. See ramp-up time in par. 3-41.
