Hello All
I have problem with my Okuma Vac drive II D8 , getting alarm 110 alarm A SDU1, i can't fix this drive by my self , so i have chance to get another vac drive but is D11, i compare this drive witch D8 and top board is the same , all connections are the same , but D11drive looks is much bigger than D8, ,bottom part is longer , both drives is for 11/7.5kw motor , D11 is from Okuma LB9 ,My is LB15 ,so i wonder if is possibly to use D11 drive instead D8
Did any one from this forum had similar problem ,
Many thanks for help
