1.5 - Radio-frequency interference

1.5.1 - General
Variable speed drives use high-speed switches (transistors,
semi-conductors) which switch high voltages (around
550VDC for 3-phase drives) at high frequencies (several
kHz). This provides better efficiency and a low level of motor
noise.
As a result, they generate radio-frequency signals which may
disturb operation of other equipment or distort measurements
taken by sensors:
- due to high-frequency leakage currents which escape to
earth via the stray capacity of the drive/motor cable and that
of the motor via the metal structures which support the motor

GENERAL INFORMATION
IP 65
- 40 °C to + 70 °C Conforming to standard IEC 68-2-1.
- 40 °C to + 70 °C
- 20 °C to + 50 °C (with power derated by 1% per °C, above 40 °C)
< 1000 m without derating.
The maximum authorised altitude is 4000 m, but above 1000 m, the continuous output current
should be derated by 1% per additional 100 m over 1000 m (eg: for an altitude of 3000 m,
derate by 20%).

- by conduction or feedback of R.F. signals on the power
supply cable: conducted emissions
- by direct radiation near to the mains supply power cable or
the drive/motor cable: radiated emissions
These phenomena are of direct interest to the user.
The frequency range concerned (radio frequency) does not
affect the energy distribution company.
Conformity of the drive is only assured when the
mechanical and electrical installation instructions
described in this manual are adhered to.
