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 Special Conditions
3.5.1 Purpose of Derating
Take derating into account when using the frequency
converter at low air pressure (high altitudes), at low
speeds, with long motor cables, cables with a large cross
section or at high ambient temperature. This section
describes the actions required.
3.5.2 Derating for Ambient Temperature
and Switching Frequency
Refer to section
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 internal temperature, load current, high voltage on the
intermediate circuit and low motor speeds. 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.
•
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 100m
altitude above 1000m, or
-
Reduce the max. ambient temperature
by 1
°
C per 200m altitude.
•
Above 2000 m altitude, contact Danfoss
regarding PELV.
An alternative is to lower the ambient temperature at high
altitudes and thereby ensure 100% output current at high
altitudes. Example: At an altitude of 2000m and a
temperature of 45
°
C (T
AMB, MAX
- 3.3K), 91% of the rated
output current is available. At a temperature of 41.7
°
C,
100% of the rated output current is available.
