We have some dc drives of model : 1P 6RA7018-6DS22-0 issue A3/V3.2. and we have also some spare drives with same model no and type. Recently We tried to replace one of the drive with the spare one. While parameter download via Drive monitor the new drive rejected parameter P078. After check we found previous drive P078=440V but the new drive P078 max range is 400V. We found R071=400 in the new drive but in old running drive P071=440V though both drive model no. is same and both drive's built in PCB cards(C98043-A7001-L2, C98043-A7002-L1-12, C98043-A7010-L2-5) model no. are also same. What might be the reason behind this? and What to do to use these new DC drive.? Need Expert suggestion.

Hello. It looks like your new drive (with r071=400V) has earlier SW version than old drive. Look at parameters r061 and r065.01. Your new drive has SW V3.22 of CUD1 and old drive SW V3.26 of CUD1. Try to update SW from V3.22 to V3.26, you can download V3.26 here. |

I have updated the software version from 3.22 to 3.26. Now parameter changed to r060.1=3.2 and r065.1=6. But still no change in r071 . still max range in P078 is 400V . What to do now? I have uploaded the parameter comparison file of before and after software update. Waiting for expert suggestion. Attachmentcompare after update.pdf (221 Downloads) |

Hello. Did you try to reset to factory settings (P051=21) after updating SW? If this will not help make a Support request. |
