Alarms are reset at every start. To avoid this reset, either:
•
Leave the brown wire unconnected, or
•
Set parameter 5-12 Terminal 27 Digital Input to [0]
No operation.
At power-up, the unit is always in stop mode. The set
reference is stored during power-down.
To set permanent start mode, disable the stop function on
the LOP as follows:
•
Connect terminal 12 to terminal 18.
•
Do not connect purple/grey wire to terminal 18.

3.5.1 Purpose of Derating

Consider derating when using the frequency converter:
•
•
•
operation
•
Gray
•
This section describes the actions required.
3.5.2 Derating for Ambient Temperature
and Switching Frequency
Refer to chapter 6.10 Derating According to Ambient
Temperature and Switching Frequency in this manual.
3.5.3 Automatic Adaptations to Ensure
Performance
The frequency converter constantly checks for critical levels
of:
•
•
•
•
Start reversing
As a response to a critical level, the frequency converter
can adjust the switching frequency and/or change the
switching pattern to ensure the performance of the
frequency converter. The capability for automatic output
current reduction extends the acceptable operating
conditions even further.

3.5.4 Derating for Low Air Pressure

The cooling capability of air is decreased at lower air
pressure.
•
•
•
At low air pressure (high altitudes).
At low speeds.
With long motor cables.
Cables with a large cross-section.
At high ambient temperature.
Internal temperature.
Load current.
High voltage on the DC link.
Low motor speeds.
Below 1000 m altitude no derating is necessary.
Above 1000 m altitude, reduce the ambient
temperature or the maximum output current.
- Reduce the output by 1% per 100 m
altitude above 1000 m, or
- Reduce the maximum ambient
temperature by 1 °C per 200 m altitude.
Above 2000 m altitude, contact Danfoss regarding
PELV.
