engrosa Posts: 7 Rating: (0)	Dear Friends ihave two semovert drive model 6SE7035-1TJ61 (250kw) one master and other slave both fixed to gear box my problem speed difference between both ... master speed is ok but slave not ok with encoder slave not move ...encoder many time changed & cable check ok with shiled ... many time made autotune p115=2-3-4-5 no new with p115= 7 test for encoder in p540 showing no result signal from master coming correct to slave but slave not move without encoder slave runing but more speed than master ..autotune p115=2-3-4-5 no new final i changed slave drive with new drive still same problem ..with encoder no speed and without encoder more speed in attachment cfc chart when i changed parameter 1 16#4 to 16#2 speed coming same and no sound in gearbox but torque for master showing -1% and slave take more load +77% after time temperature fault f023because load and slave trip and sound came to gear box big sound i want to run with encoder and feedback missing please help Attachment 12.jpg (355 Downloads)

engrosa Posts: 7 Rating: (0)	Dear Sir thank you for your reply master motor runing very good reference came from HMI to master then going to slave same but problem slave motor not move with encoder p100=4 if you change p100=3 without encoder motor move but with speed more if S.P as example 15 m/min master showing 15m/min & slave showing 52 m/min if increase s.p difference between master and slave minimum 35m/min difference between master and slave if autotune doing p115 = 2-3-4-5 same different

jkp Posts: 27 Rating: (1)	Is the reference going to slave from master through SCB? if so please check SCB of master & slave both.If reference going to slave through CUVC analog O/P then try to adjust the value of P643. Is the encoder feedback to the slave trough SBP or DTI?

engrosa Posts: 7 Rating: (0)	i dont have DTI card .. i have CUVC card with encoder HTL and i changed also but same now i changed drive parameter in CFC from 16#4 to 16#2 these mean droop compensation and speed came same but problem now 2 motor take more load at speed 300 going to 85 % and canot increase speed .i made p115=2/3/4/5 same... download parameter same i need any parameters to decrease load
