12 Technical data
12.1 Drive technical data
12.1.1 Power and current ratings
The power ratings for the 480V, 575V and 690V configurations are
shown in Table 12-1, Table 12-2 and Table 12-3.
The continuous current ratings given are for a maximum ambient
temperature of 40°C and an altitude of 1000m. For operation at higher
temperatures and altitudes derating is required.
The maximum continuous output current rating of the drive should be
‘derated’ for operation at altitudes above 1000m. The derating is to be
1% derating of rated output current per 100m above 1000m to a
maximum derating of 20% at 3000m.

Maximum continuous input current
The values of maximum continuous input current are given to aid the
selection of cables and fuses. These values are stated for worst-case
conditions.
For current ratings above 1850A then parallel connection of the drives is
required. However, this function is not implemented on firmware
versions V01.05.00 and earlier.
12.1.2 Typical short-term overload limits
The maximum percentage overload limit changes depending on the
selected motor
Variations in motor rated current will result in changes in the maximum
possible overload as detailed in the
Mentor MP
Advanced User Guide
.
Figure 12-1 can be used to determine the maximum overload duration
available for overloads between 100% and 150%. For example the
maximum overload available for a period of 60 seconds is 124%.
Figure 12-1 Maximum overload duration available
Overload of 150% for 30s is available up to a maximum of 10 repetitions
per hour.
