12.1.17 Acoustic noise
The heatsink fan generates the majority of the acoustic noise produced by
the drive. The heatsink fan on size 0 to 2 is a dual speed fan and on size 3
to 6 it is a variable speed fan. The drive controls the speed at which the
fan runs based on the temperature of the heatsink and the drive's thermal
model system. On size 4 to 6 the minimum speed of the heatsink fan is 0
rpm. The size 3 to 6 is also installed with a variable speed fan to ventilate
the capacitor bank.
Table 12-10 gives the acoustic noise produced by the drive for the
heatsink fan running at the maximum and minimum speeds.

12.1.20 Input current, fuse and cable size ratings
The input current is affected by the supply voltage and impedance.
Typical input current
The values of typical input current are given to aid calculations for power
flow and power loss.
The values of typical input current are stated for a balanced supply.
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 the worst case
condition with the unusual combination of stiff supply with bad balance.
The value stated for the maximum continuous input current would only
be seen in one of the input phases. The current in the other two phases
would be significantly lower.
The values of maximum input current are stated for a supply with a 2%

negative phase-sequence imbalance and rated at the maximum supply
