Hello, I guess you are trouble shooting the problem which you faced as mentioned in this Whats wrong in this circuit? topic. Please set the parameters as explained in manual for appropriate application, i.e. for direction reversal or for braking. BTW you need to use 2pole DC contactor at output & should control its operation via drive. Since you have not mentioned DC motor field current, I presume it would not be more than 32 A. (Drive rated field current capacity is 40 Amp) You can select CONTACTOR, SIZE 2, 2-POLE coil voltage is 230 V AC 50 Hz for your application. Hope this helps. |
