We have 10 DC motors are controlling from Siemens-DC Drives -6RA24. There is only one drive & these all motors are Armature controlled and connected on same DC bus controlled by DC Drives. . Fields of all 10 DC motors are seperately excited. 2 nos of Tacho connected for feedback on 2 Motors out of these 10.. One tacho is selected at a time and used for feedback to the drives..
Now the problem is that when we changeover the tacho from tacho-1 to tacho-2 all 10 motors armature fuse blown out. But when we changeover the tacho from tacho-2 to tacho-1 Drives working fine and none of the fuse blown out. Also Drives working fine on either tacho selection, problem comes only during tacho changeover.. Note: Both tacho feedback voltages are almost same. Can somebody help me . Thanks in advance. |
