FC 300 Operating Instructions
How to Programme
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
R
S
, the rotor resistance R
r
, the stator leakage
reactance x
1
, the rotor leakage reactance X
2
and
the main reactance X
h
.
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.
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
*
0.000 Unit
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.
Speed control, closed loop: RPM Torque control,
speed feedback: Nm
3-03 Maximum Reference
Range:
Par. 3-02 - 100000.000
*
1500.000 Unit
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.
Speed control, closed loop: RPM
Torque control, speed feedback: Nm.
3-41 Ramp 1 Ramp-up Time
Range:
0.01 - 3600.00 s
*
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
*
s
Function:
The ramp-down time is the deceleration time from
the rated motor speed n
M,N
(par. 1-23) to 0 RPM,
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.
