AKD 5000
Programming
For 87 Hz operation with 230/400 V motors, set
the nameplate data for 230 V. Adapt parameter
202
Output frequency high limit
and parameter 205
Maximum reference
to the 87 Hz application.
NB!:
If a delta connection is used, the rated
motor frequency for the delta connected
must be selected.
NB!:
If the setting in parameter 102-109 is changed,
the parameters 110-118 will return to factory
setting. If using special motor characteristics a
change in parameter 102-109 affects parameter 422.
105 Motor current (MOTOR CURRENT)
Value:
0.01 - I
AKD,MAX
[0.01 - XXX.X]
Depends on the choice of motor.
Function:
The rated motor current I
M,N
forms part of the
frequency converter calculations i.a. of torque
and motor thermal protection.
Description of choice:
Select a value that equals the nameplate
data on the motor.
Enter the value in Ampere.
NB!:
It is important to enter the correct value, since
this forms part of the VVC
plus
control feature.
NB!:
If the setting in parameter 102-109 is changed,
the parameters 110-118 will return to factory
setting. If using special motor characteristics a
change in parameter 102-109 affects parameter 422.
106 Rated motor speed
(MOTOR NOM. SPEED)
Value:
100 - 60000 rpm (RPM)
[100 - 60000]
Depends on the choice of motor.
Function:
This is where the value is selected that corresponds
to the rated motor speed n
M,N
, which can be
seen from the nameplate data.
Description of choice:
The rated motor speed n
M,N
is used i.a. for calculating
the optimal slip compensation.
NB!:
It is important to enter the correct value,
since this forms part of the VVC
plus
control
feature. The max. value equals f
M,N
x
60. Set f
M,N
in parameter 104.
NB!:
If the setting in parameter 102-109 is changed,
the parameters 110-118 will return to factory
setting. If using special motor characteristics a
change in parameter 102-109 affects parameter 422.
107 Automatic motor adaptation, AMA
(AUTO MOTOR ADAPT)
Value:
✭
Adaptation off (OFF)
[0]
Adaptation on, R
S
and X
S
( ENABLE (RS,XS))
[1]
Adaptation on, R
S
(ENABLE (RS))
[2]
Function:
If this function is used, the frequency converter
automatically sets the necessary control parameters
(parameters 108/109) with the motor stationary.
Automatic motor adaptation ensures optimum
use of the motor.
For the best possible adaptation of the frequency
converter, it is recommended to run AMA
on a cold motor.
The AMA function is activated by pressing the
[START] key after selecting [1] or [2].
See also section
Automatic motor adaptation
.
The section
Automatic motor adaption, AMA, via
AKD software dialog
shows how automatic motor
adaptation can be activated by means of AKD Software
Dialog. After a normal sequence, the display will read
"ALARM 21". Press the [STOP/RESET] key. The
frequency converter is now ready for operation.
Description of choice:
Select
Enable, R
S
and X
S
[1] if the frequency
converter is to be able to carry out automatic
motor adaptation of both the stator resistance
R
S
and the stator reactance X
S
.
Select
Optimisation on, R
S
[2] if a reduced test
is to be carried out, in which only the ohmic
resistance in the system is determined.
