Otis ht131 gearless machine. Car runs fine with no load. I put 2000 pounds this morning and nothing..... Drive faults out. I did notice that parameter 625(torque mode) is set to 0 while the other running car is set to 1. Where 0= zero torque command and 1= velocity reg. Output. I cant change it and im not sure if its adjustable. I also bypassed the choke as someone recommended from engineering with no positive results. Im waiting for the motor man to check the armature and fields out. Fingers crossed !
