Motor chokes
The motor reactor is in the output of the frequency inverter. Its
rated operational current must always be greater than/equal to the
rated operational current of frequency inverter.

(maximum power supply: 750 V ±0%, maximum permitted frequency: 200 Hz)

When multiple motors are connected in parallel in the
motor reactor, the rated operational current of the motor
reactor must be greater than the total current of all
motors.

1) The rated operational currents of the allocated motor outputs apply for normal four-pole, internally and externally ventilated three-phase
asynchronous motors with 1500 min
-1
(at 50 Hz) and 1800 min
-1
(at 60 Hz).
2) Guide value (calculated), no standard rating.
