FC 300 Operating Instructions
AMA ensures optimum use of the motor. For the
best possible adaptation of the frequency converter,
run AMA on a cold motor.
Select Enable complete AMA, if the frequency
converter is to carry out AMA of the stator resistance

Select Reduced AMA if a reduced test is to be
carried out, in which only the stator resistance R
the system is determined.
AMA cannot be carried out while the motor is
running.
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 adaptation, 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.

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:
in
s
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. 1-23),
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
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.
