Danfoss VLT FC 100 Operating Instructions

6. Press [Hand on]. A progress bar indicates if the
AMA is in progress.
Stop the AMA during operation
1. Press [Off] - the frequency converter enters into
alarm mode and the display shows that the AMA
was terminated by the user.
Successful AMA
1. The display shows “Press [OK] to finish AMA”.
2. Press [OK] to exit the AMA state.
Unsuccessful AMA
1. The frequency converter enters into alarm mode.
A description of the alarm can be found in the
Warnings and Alarms chapter.
2. "Report Value” in the [Alarm Log] shows the last
measuring sequence carried out by the AMA,
before the frequency converter entered alarm
mode. This number along with the description of
the alarm will assist you in troubleshooting. If
contacting Danfoss for service, make sure to
mention number and alarm description.
NOTE
Unsuccessful AMA is often caused by incorrectly registered
motor name plate data or a too big difference between
the motor power size and the frequency converter power
size.

Additional Connections
3.7.1 Mechanical Brake Control
In hoisting/lowering applications, it is necessary to be able
to control an electro-mechanical brake:
•
Control the brake using any relay output or
digital output (terminal 27 or 29).
•
Keep the output closed (voltage-free) as long as
the frequency converter is unable to ‘support’ the
motor, for example due to the load being too
heavy.
•
Select [32] Mechanical brake control in parameter
group 5-4* for applications with an electro-
mechanical brake.
•
The brake is released when the motor current
exceeds the preset value in 2-20 Release Brake
Current.
•
The brake is engaged when the output frequency
is less than the frequency set in 2-21 Activate
Brake Speed [RPM] or 2-22 Activate Brake Speed
[Hz], and only if the frequency converter carries
out a stop command.
If the frequency converter is in alarm mode or in an over-
voltage situation, the mechanical brake immediately cuts
in.
