* Cable lengths in excess of the specified values may be used only
when special techniques are adopted; refer to the supplier of the
drive.
** The default switching frequency for all versions of Unidrive is 3kHz,
except Unidrive LFT, which is 9kHz.
See section 4.5.1 Cable types and lengths on page 41 for further
limitations on motor cable length.

11.1.17 Braking resistor values
11.1.18 Acoustic noise
The fan generates the majority of the acoustic noise produced by the
drive. The Unidrive LFT has a slower speed fan than the Unidrive or
Unidrive VTC and hence generates less noise. Unidrive LFT sizes 1 and
2 are fitted with temperature controlled variable speed fans that run at
the minimum speed until the temperature reaches 30
o
C (86
o
F) and
increase in speed until the temperature reaches 45
o
C (113
o
F), where
they will be running at the maximum speed.
Values quoted are at a distance of 1m from the drive.
