Jumper Terminal 12 And; Automatic Motor Adaptation (Ama) - Danfoss VLT AutomationDrive FC 360 Quick Manual

Quick Start

1.4 Jumper Terminal 12 and 27

When using factory default programming values, jumper
wire may be required between terminal 12 and terminal 27
for the frequency converter to operate.
•
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 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 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
To run AMA using the numeric LCP (NLCP)
1. By default parameter setting, connect terminal 12
and 27 before running AMA.
2. Enter the main menu.
3. Go to parameter group 1-** Load and Motor.
4. Press [OK].
5. Set motor parameters using name plate data for
parameter group J1-1-2* Motor Data.
6. Set motor cable length in 1-42 Motor Cable Length
7. Go to 1-29 Automatic Motor Adaptation (AMA).
8. Press [OK].
9. Select [1] Enable complete AMA.
10. Press [OK].
11. The test will run automatically and indicate when
it is complete.
