Recommendations for use
of the motor/speed controller combination
Additional motor connected downstream of the speed controller
- Comply with the sequence shown t1 = 20 ms,
t2 = 1,5 s (demagnetization of the motor)
- If the power of the motor to be connected is low in comparison with the rating of the speed
controller, and it produces an acceptable overload (maximum current < controller transient
current), connection on the run is possible
Direct coupling of the motor to the mains "BY-PASS"
- Comply with the sequence shown : t1 = 20 ms,
t2 = 1,5 s (demagnetization of the motor)
Use of a brake motor
- Electric brake
Make sure that the brake winding is brought out to terminals, without a common point to the
stator The brake should be supplied separately at its rated voltage and switched on
simultaneously with the motor.
- Tapered rotor motor
The brake is released by the magnetic field of the motor
Experience shows that this kind of motor can be used with a frequency inverter, but
requires special adjustments. Refer to part 2 of this document "Special Applications" (p 81)
Use of a synchronized asynchronous motor
Operation is possible provided the slip compensation has been overridden (p 45)
