Danfoss VLT Midi Drive FC-280P4K0 [35/136] Notice

Danfoss VLT Midi Drive FC-280PK37 [35/136] Notice
1-26 Motor Cont. Rated Torque
Range: Function:
parameter is valid for PM, non-salient SPM
and salient IPM motors only.
1-29 Automatic Motor Adaption (AMA)
Option: Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
NOTICE
Terminal 27 digital input
(parameter 5-12 Terminal 27 Digital Input)
has coast inverse as the default setting.
This setting means that AMA cannot be
performed if terminal 27 is switched o.
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters
(parameter 1-30 Stator Resistance (Rs) to
parameter 1-35 Main Reactance (Xh)) while the
motor is stationary.

O No function.
[1] Enable
Complete
AMA
Depending on the option selected in
parameter 1-10 Motor Construction, the AMA is
performed on dierent parameters.
If [0] Asynchron is selected, the AMA is
performed on:
- Parameter 1-30 Stator
Resistance (Rs).
- Parameter 1-31 Rotor Resistance
(Rr).
- Parameter 1-33 Stator Leakage
Reactance (X1).
- Parameter 1-35 Main Reactance
(Xh).
If [1] PM, non-salient SPM, non Sat is
selected, the AMA is performed on:
- Parameter 1-30 Stator
Resistance (Rs).
- Parameter 1-37 d-axis
Inductance (Ld).
If [2] PM, salient IPM, non Sat is selected,
the AMA is performed on:
1-29 Automatic Motor Adaption (AMA)
Option: Function:
- Parameter 1-30 Stator
Resistance (Rs).
- Parameter 1-37 d-axis
Inductance (Ld).
- Parameter 1-38 q-axis
Inductance (Lq).
If [3] PM, salient IPM, Sat is selected, the
AMA is performed on:
- Parameter 1-30 Stator
Resistance (Rs).
- Parameter 1-37 d-axis
Inductance (Ld).
- Parameter 1-38 q-axis
Inductance (Lq).
- Parameter 1-44 d-axis
Inductance Sat. (LdSat).
- Parameter 1-45 q-axis
Inductance Sat. (LqSat).
[2] Enable
Reduced
AMA
Performs a reduced AMA of the stator resistance
R
s
(parameter 1-30 Stator Resistance (Rs)) in the
system only. If an LC lter is used between the
frequency converter and the motor, select this
option.
When parameter 1-10 Motor Construction is set to options
that enable permanent motor mode, the only option
available is [1] Enable Complete AMA.
Activate the AMA function by pressing [Hand On] after
selecting [1] Enable Complete AMA or [2] Enable Reduced
AMA. After a normal sequence, the display reads: Press [OK]
to nish AMA. After pressing [OK], the frequency converter
is ready for operation.
