7-5 Zero Phase Reactors 
You can also suppress interference by installing a zero phase reactor at the main input or the motor 
output of the drive, depending on the location of the interference. Delta provides two types of zero phase 
reactors to solve interference problems. 
A. Casing with mechanical fixed part 
This solution is for the main input/motor output side and can withstand higher loading, and be used at 
higher frequencies. You can get higher impedance by increasing the number of turns.

B. Casing without mechanical fixed part 
This  solution  has  higher  performance:  high  initial  magnetic  permeability,  high  saturation  induction 
density, low iron loss and perfect temperature characteristic. If the zero phase reactor does not need to be 
fixed mechanically, use this solution.
