1.4 Jumper Terminal 12 and 27
A jumper wire may be required between terminal 12 and
terminal 27 for the frequency converter to operate when
using factory default programming values.
•
Digital input terminal 27 is designed to receive an
24 V DC external interlock command. In many
applications, the user wires an external interlock
device to terminal 27
•
When no interlock device is used, wire a jumper
between control terminal 12 to terminal 27. This
provides in internal 24 V signal on terminal 27
•
No signal present prevents the unit from
operating
1.5 Automatic Motor Adaptation (AMA)
Automatic motor adaptation (AMA)
It is highly recommended to run AMA because it is a test
procedure that measures the electrical characteristics of
the motor to optimize compatibility between the
frequency converter and the motor under VVC
plus
mode.
•
The frequency converter builds a mathematical
model of the motor for regulating output motor
current thus enhancing motor performance.
•
Some motors may be unable to run the complete
version of the test. In that case, select
Enable
reduced AMA
•
If warnings or alarms occur, see
6 Warnings and
Alarms
•
Run this procedure on a cold motor for best
results
NOTE
AMA does not cause the motor to run and it does not
harm the motor.
To run AMA using the numeric LCP (NLCP)
1.
Enter the main menu.
2.
Go to parameter group
1-** Load and Motor
.
3.
Press [OK].
4.
Set motor parameters using name plate data for
parameter
group 1-2* Motor Data
.
5.
Set motor cable length in
1-42 Motor Cable Length
6.
Go to
1-29 Automatic Motor Adaptation (AMA)
.
7.
Press [OK].
8.
Select
[1] Enable complete AMA
.
9.
Press [OK].
10.
The test will run automatically and indicate when
it is complete.
NOTE
By default parameter setting, connect terminal 12 and 27
before running AMA.
