FC 300 Instruction Manual
How to Program
1-24 Motor Current
Range:
Motor type dependent.
Function:
The value should equal the nameplate data on
the connected motor. Data is used for calculating
torque, motor protection, etc.
NOTE
Changing the value in this parameter
affects the setting of other parameters.
Par. 1-24 cannot be changed while
the motor is running.
1-25 Motor Nominal Speed
Range:
100. - 60000 . RPM
*
ExpressionLimitRPM
Function:
The value should equal the name plate data
on the connected motor. The data is used for
calculating motor compensations.
1-29 Automatic Motor Adaptation (AMA)
Option:
*
OFF [0]
Enable complete AMA [1]
Enable reduced AMA [2]
Function:
If the AMA function is used, the adjustable frequency
drive automatically sets the n e cessary motor
parameters (par. 1-30 to par. 1-35) with the
motor stationary. AMA ensures optimum use of t he
motor. For the best adaptation of the adjustable
frequency d rive, run AMA on a cold motor.
Select Enable complete AMA, if the adjustable
frequency d rive is to carry out A MA of the stator
resistance R

.
Select Reduced AMA if a reduced test is to be
carried out, in which only the stator resistance
R
s
in the system is determined.
AMA cannot be carried out while the motor is running.
AMA cannot be c arried out on permanent
magnet motors.
Activate the A MA function by pressing [Ha n d 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 adjustable frequency
drive is now ready for operation.
NOTE
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 1 0 min, depending on
the power rating of the motor.
NOTE
Avoid externally generating torque
during AMA.
NOTE
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
Option:
-100000.000 - MaxReference (par. 3-03)
*
0.000
Function:
The Minim u m 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.
Speed control, closed loop: RPM Torque control
Speed feed back: Nm
3-03 Maximum Reference
Option:
MinReference (par. 3-02) - 100000.000
*
1500.000
Function:
The Maximum reference is the h ighest value
obtained by the sum of all references. The unit
follows the choice of configuration in par. 1-00.
Speed control, closed loop: RPM
Torque control, speed fee dback: Nm
