Recommendations for use
of the motor/speed controller combination
Operation at constant
This type of operation is possible providing the motor winding torque is adjusted, and the
torque in overspeed
voltage / frequency ratio adapted The various possibilities are specified below
Example : ATV-452--- (380/415 V)
motor 240 ( A)/415 V (A)
Motor connected in k (coupling 1)
Motor connected at A (coupling 2)
Operation at constant torque
Operation at constant torque
up to 50 (60) Hz
up to 87 (104) Hz
Ensure that the motor is suitable for overspeed operation
In the event of operation with low voltage connection (connection 2), the rated current to be
used for speed controller selection is that taken by the motor when connected in this
configuration
Example operation of a 4 kW 1500 rpm 415 V 50 Hz motor at 87 Hz, the power at 2610
rpm is 7 kW Rated current at 240 V 16,5 A Speed controller selected ATV-452U75 (7,5 kW
- 17,5 A)

Installation of the motor
Mount and couple the motor carefully, so as to eliminate any possible problems with
vibrations and resonance
