5.3 AC output chokes
The ADL500
inverter can be used with standard motors or motors designed specifically for use with inverters.
The latter usually have a higher isolation rating to better withstand PWM voltage Examples of reference regulations
are provided below: motors designed for use with inverters do not require any specific filtering of output from the
inverter. For standard motors, especially with long cable runs (typically over 100 m) an output choke may be necessary
to maintain the voltage waveform with the specified limits.
The range of recommended chokes are listed in the following table. The rated current of the chokes should be approx.
20% higher than that of the inverter in order to take into account additional losses due to modulation of the output
waveform.

Note !
With the inverter operated at the rated current and a frequency of 50 Hz, the output chokes cause a voltage drop of approx. 2% of the output voltage.

Braking resistors may be subject to unexpected overloads due to faults.
Resistors MUST be protected using thermal cutouts. These devices must not interrupt the circuit in which the resistor is
inserted but their auxiliary contact must cut off the power supply to the power section of the drive. If the resistor requires a
protection contact, this must be used together with that of the thermal cutout.
A la suite de pannes, les résistances de freinage peuvent être sujettes à des surcharges imprévues. La protection des
résistances au moyen de dispositifs de protection thermique est absolument capitale. Ces dispositifs ne doivent pas inter-
rompre le circuit qui abrite la résistance, mais leur contact auxiliaire doit couper l’alimentation du côté puissance du drive.
