1.3.6 Load Sharing/Brake

Use 6.3 mm insulated Faston plugs designed for high
voltage for DC (load sharing and brake).
Contact Danfoss or see Load sharing instruction VLT
for load sharing and VLT
Brake for brake.
Load sharing
Connect terminals -UDC and +UDC/+BR.
Brake
Connect terminals -BR and +UDC/+BR (not applicable for
enclosure size M1).
NOTICE
Voltage levels of up to 850 V DC may occur between
terminals +UDC/+BR and -UDC. Not short circuit
protected.

1.4 Programming

1.4.1 Programming on Automatic Motor
Adaptation (AMA)
For detailed information on programming, see VLT
Drive FC 51 Programming Guide.
NOTICE
The frequency converter can also be programmed from a
PC via RS485 com-port by installing the MCT 10 Set-up
Software.
This software can either be ordered using code number
130B1000 or downloaded from the Danfoss web site:

Main Menu
For access to all parameters.
Navigation keys
[Back]: For moving to the previous step or layer in the
navigation structure.
▲ ▼
[ ] [ ]: For manoeuvring between parameter groups,
parameters and within parameters.
[OK]: For selecting a parameter and for accepting changes
to parameter settings.
Pressing [OK] for more than 1 s enters Adjust mode. In
Adjust mode, it is possible to make fast adjustment by
▲ ▼
pressing [ ] [ ] combined with [OK].

Press [ ] [ ] to change value. Press [OK] to shift between
digits quickly.
To exit Adjust mode, press [OK] more than 1 s again with
changes saving or press [Back] without changes saving.
Operation keys
A yellow indicator light above the operation keys indicates
the active key.
[Hand On]: Starts the motor and enables control of the
frequency converter via the LCP.
[Off/Reset]: The motor stops. If in alarm mode, the motor
resets.
[Auto On]: The frequency converter is controlled either via
control terminals or serial communication.
[Potentiometer] (LCP12): The potentiometer works in 2
ways depending on the mode in which the frequency
converter is running.
In Auto On mode, the potentiometer acts as an extra
programmable analog input.
In Hand On mode, the potentiometer controls local
reference.
1.4.2 Programming on Automatic Motor
Tuning (AMT)
Run AMT to optimise compatibility between the frequency
converter and the motor in VVC
•
The frequency converter builds a mathematical
model of the motor for regulating output motor
current thus enhancing motor performance.
•
Run this procedure on a cold motor for best
results. To run AMT, use the numeric LCP (NLCP).
There are 2 AMT modes for frequency converters.
