Analog Tacho 100RPM = 60V. I have done field current optimization and armature current optimization without an error with load.And check the motor running properly upto 400 RPM. we are unable to do Speed Otimization and Field weakning we are getting some faults. F60052 ( Impermissible parameter setting for this optimization ), F60031 (Excessive setpoint /Actual value deviation), and F60300 (Commutative failed). 1. Please help for field weakning and speed optimization. 2 Tell the proper procedure for optimization. 3 Also suggest the parameters should set for field weakning optimization. Thanks in Advance

Did you enable field-weakening in P50081? fault value 103. yes i have enable field-weakning also, select analog tacho..... but continiously fault occurs. I dont know the proper method to do field weakning i read manual and done optimization.

Look at the description of fault F60052 and also notes about value 103: Note for fault value = 103: - r50047[1]: 1 = Sequence control optimization run, 2 = Field optimization run, 3 = EMF optimization run - If r50047[1] = 1, r50047[2...3] are not relevant - r50047[2]: Parameter number - r50047[3]: Parameter value Check the values of r50047.

sparten Posts: 205 Rating: (11)	Hello amsd, Please check feedback of your connected f/b device (encoder or /techo).. whether your are getting proper f/b or not? if you are getting proper f/b then first performe speed controller optimization(P50051=26) then run drive upto base speed measured Armature voltage...if your getting motor rated armature voltage .. then enable fieldweakning and performed Fieldweakning tunning(P50051=27)...

nguyenlong89hui Posts: 28 Rating: (0)	hello KSN thanks for reply i convert to DC master to Sinamis DCM so i need to optimization Driver all mode or need to one option? this is file of parameter old driver Attachment MASTER_tmpchane.zip (605 Downloads)

If you make an upgrade from 6RA70 to 6RA80, then you need to run the same optimization runs, that were made in 6RA70. Basically optimizations for armature/field current controller and speed controller arenecessarily.

nguyenlong89hui Posts: 28 Rating: (0)	thank sir i see on old driver its set some of mode in optimization(mode 25,26,27).one of them is field weakening mode but i can't see any encoder or tacho in motor DC.so i can't optimization in mode 27 .have you give me some idea?
